Charlie Russel is saying the same thing.
-> ISA Server -> Configuration -> General -> Define Connection Limits -> Connection Limit -> Limit the number of connection -> Connection limit per client (TCP and non-TCP)
Do me a favor and check what value is there?
If 40...try 160 for grins.

Ok, in my strive to find out why I am having problems with just one URL, I was attempting to make a transaction on this URL, and my firewall client reported it was unable to connect to the ISA server.
The Firewall Client is for ISA 2004. I have manually select the ISA server selected, with the server name. Just like I had with ISA 2000. The one thing I find funny is that instead of having the firewall client manager in the control panel, it's now in Programs (off the start menu). Is everyone elses like that? Is there a way in ISA 2004 to find why I am getting disconnected?

Hello Clevere,
Thank you for posting to the SBS Newsgroup.
From your post, I think your issue is your firewall clients cannot connect to the ISA server. If I have misunderstood your issue, please let me know.
Before we go any further, I need to confirm with you for some information:
1. I am not quite clear your meaning "attempting to make a transaction on this URL", please explain it in detailed.
2. I assume that your firewall clients are using ISA 2004, what is your ISA server version, 2000 or 2004?
3. Does this issue happen to all the firewall clients or some of them?
4. Can you manually or automatically connect the firewall client to connect to the ISA server? To do so,
a) On of the problematic client workstation, in the taskbar, double click the Firewall Client icon, and Firewall Client Options comes out.
b) Check the box Automatically/Manually detect ISA server.
c) Click OK, and test whether it connects or not.
5. Also in the Firewall Client icon, make sure that you have typed the right ISA Server address to connect. You can fill in the blank with the ISA server FQDN or IP address, and test whether it is connected.
6. Make sure your ISA service is Started.
Thanks for your time. I am looking forward to hearing from you soon.
Best regards,
Brandy Nee

Brandy- Here are you answers:
From your post, I think your issue is your firewall clients cannot connect to the ISA server. If I have misunderstood your issue, please let me know. Before we go any further, I need to confirm with you for some information: 1. I am not quite clear your meaning "attempting to make a transaction on this URL", please explain it in detailed
.
I am attempting to connect to my online banking system. It's a CGI based application that lets you access your bank information. I can email you the URL, but I can't post it online. The first time I attempt to access the feature of this site, (getting my account info), the page will not load, the page can't be displayed. IE reports Cannot find server or DNS Error Internet Explorer If I click back, and then click continue (on the webpage to access my account information) everything works. If I attempt to access anything internet related when the page won't load, my Firewall client software loses it's connection with the ISA server.
2. I assume that your firewall clients are using ISA 2004, what is your ISA server version, 2000 or 2004
?
ISA 2004 Firewall Client, ISA 2004 Server
3. Does this issue happen to all the firewall clients or some of them
? I'm only testing this on one workstation at this time, but the URL access problem happens across all the machines on the network. This was not a problem with ISA 2000.
4. Can you manually or automatically connect the firewall client to connect to the ISA server? To do so
,
I have it setup manually.
a) On of the problematic client workstation, in the taskbar, double click the Firewall Client icon, and Firewall Client Options comes out. b) Check the box Automatically/Manually detect ISA server. c) Click OK, and test whether it connects or not. 5. Also in the Firewall Client icon, make sure that you have typed the right ISA Server address to connect. You can fill in the blank with the ISA server FQDN or IP address, and test whether it is connected
.
I've done this, works everytime. Except when the firewall client loses connection to the ISA server. It then takes about 15 seconds before it can find the ISA server
6. Make sure your ISA service is Started. It's running on the SBS2K3 box .. quite happily...
Thanks for your time. I am looking forward to hearing from you soon
.
This is what my ISA 2004 log says when I attempt to connect to the web site in question:

Hmm .. I made an interesting discovery. If I change the server name in the firewall client to the server IP address, I get the slow page load, but I can connect to that site without problem.
The firewall client is not able to find the ISA server every time I can't access this web site. What does that indicate?

I may have spoken too soon on the finding the ISA server via the IP address...
But the firewall client is losing connection or dropping it with the ISA server.

Hello Clevere,
Thank you for posting back.
From your reply, I think this maybe is a very complicated issue. Please understand that we may take time to do more further research, and we also need your assistance to collect more error information.
1. Unlike ISA Server 2000, it is by design that the Firewall Client of ISA 2004 is listed in the Programs as you mentioned, so please do not worry about it.
2. When the connection is rejected by the ISA, the Firewall Client will temporarily display "not connected" for about 15 seconds.
3. Please configure ISA's internal NIC as the proxy in the IE | Internet Options | Connections tab | LAN Settings button, and then test whether it works now. To do so, type the IP address of the ISA internal NIC into the proxy server name, and then type the Port of internal NIC that the ISA is monitoring into the port box.
4. Have you installed the SBS 2K3 SP1 Premium Edition? Does the ISA 2K4 come from the SBS 2K3 SP1 Premium Edition or from the retail version of the ISA Server 2004?
Thanks for your time. I am looking forward to your reply.

Hi Brandy- Thanks for replying, I'd really like to know why ISA 2004 is killing my connection :)
Here are you answers:
From your reply, I think this maybe is a very complicated issue. Please understand that we may take time to do more further research, and we also need your assistance to collect more error information. 1. Unlike ISA Server 2000, it is by design that the Firewall Client of ISA 2004 is listed in the Programs as you mentioned, so please do not worry about it
.
Ok, no worries there then.
2. When the connection is rejected by the ISA, the Firewall Client will temporarily display "not connected" for about 15 seconds
.
That explains something, that ISA is rejecting the connection from my workstation, but why?
3. Please configure ISA's internal NIC as the proxy in the IE | Internet Options | Connections tab | LAN Settings button, and then test whether it works now. To do so, type the IP address of the ISA internal NIC into the proxy server name, and then type the Port of internal NIC that the ISA is monitoring into the port box
.
Did that, didn't change a thing. As soon as I try to access information on www.customwaNOSPAM.com The firewall client loses connection with the server, and poof, there goes my internet connection.
4. Have you installed the SBS 2K3 SP1 Premium Edition? Does the ISA 2K4 come from the SBS 2K3 SP1 Premium Edition or from the retail version of the ISA Server 2004
?
Yes, I installed SBS 2k3 SP1 Premium Edition. The ISA 2004 comes from the SBS2K3 SP1 Premium CD set you order over the internet. I upgraded as follows:
Downloaded SBS2K3 SP1 (per the Microsoft instructions) from the internet, installed it, and was up and running with little trouble. Ordered my CD's, got My CD's, and install ISA 2004... that's when the problem started to happen. I don't know if you saw this in my last post, but this is what ISA is saying when I attempt to access that web site:
192.168.16.11 PINE-FOREST\chris Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322) Y 2005-05-28 19:58:29 w3proxy VOLE - www.customwa.com 66.224.153.131 443 - 596 364 SSL-tunnel TCP - www.customwa.com:443 - Inet 995 - SBS Internet Access Rule - Internal External 0x8a Failed 192.168.16.11 anonymous Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322) N 2005-05-28 19:58:29 w3proxy VOLE - www.customwa.com 192.168.16.2 443 - - 569 SSL-tunnel TCP - www.customwa.com:443 - Inet 407 - SBS Internet Access Rule - Internal External 0x800 Allowed 192.168.16.11 anonymous Mozilla/4.0 (compatible; MSIE 6.0

I am using IE, with the latest Service Pack install on Windows XP SP2.
Just out of curiousity, and from a recommendation from another SBS member, I deleted all the ISA rules, and re-ran the Connect to the Internet Wizard. It recreated all the appropriate ISA rules, but my problem still exists.

Hello Clevere,
Thank you for posting back.
As I have stated in my last reply, this is a very complcated issue. To perform more further research, please take your time and help us to gather the following information:
[Note]: This information is very important for us to isolate and resolve this issue.
1. IPCONFIG /ALL results on the SBS.
2. The network diagram that includes the IP addresses range for each network.
3. ISA Info:
1) Download the file from the following URL:
http://www.isatools.org/isainfo/ISAInfo.zip
2) Extract all files to a folder on ISA server.
3) Double click Isainfo.js. This will generate 2 files ISAInfo2004-<computer-name>.log and ISAInfo2004-<computer-name>.xml in the current folder.
4) Attach the files and send it to v-bra...@xxxxxxxxxxxxx
4. Gather the ISA logs:
1) Schedule a down time.
2) Open ISA 2004 management console.
3) Expand the server node and highlight 'Monitoring'.
4) In the right pane, switch to the 'Logging' tab, make sure the 'Task Pane' is showed there.
5) In the 'Task Pane', click 'Configure Firewall Logging' under 'Logging Tasks', and then switch the 'log storage format' from 'MSDE database' (default) to 'File'.
6) Switch to the 'Fields' tab, click 'Select All', and then click OK.
7) In the 'Task Pane', click 'Configure Web Proxy Logging' under 'Logging Tasks', and then switch the 'log storage format' from 'MSDE database' (default) to 'File'.
8) Switch to the 'Fields' tab, click 'Select All', and then click OK.
9) Click 'Apply' to save changes and update the configuration.
10) Temporarily disable the Firewall service. To do that, please click Monitoring | Services tab, and then right click 'Microsoft Firewall' to choose 'Stop'.
11) Clear the current existing W3C logs. To do that, go to the log saving directory and clean any existing .W3C logs. By default, the logs will be saved to 'C:\Program Files\Microsoft ISA Server\ISALogs'. (Some MDF may not be able to deleted, that's normal.) You may backup them first and then delete them.
12) Go back to the ISA 2004 management console, and then Start the stopped 'Microsoft Firewall' service.
13) Reproduce the problem, stop the service, and then attach the resulting W3C files to the newsgroup.
14) Please also let me know the IP address of the testing clients so that I can filter the data.

Hello Clevere,
Thank you for posting back.
As I have stated in my last reply, this is a very complcated issue. To perform more further research, please take your time and help us to gather the following information:
[Note]: This information is very important for us to isolate and resolve this issue.
1. IPCONFIG /ALL results on the SBS.
2. The network diagram that includes the IP addresses range for each network.
3. ISA Info:
1) Download the file from the following URL:
http://www.isatools.org/isainfo/ISAInfo.zip
2) Extract all files to a folder on ISA server.
3) Double click Isainfo.js. This will generate 2 files ISAInfo2004-<computer-name>.log and ISAInfo2004-<computer-name>.xml in
the
current folder.
4) Attach the files and send it to v-bra...@xxxxxxxxxxxxx
4. Gather the ISA logs:
1) Schedule a down time.
2) Open ISA 2004 management console.
3) Expand the server node and highlight 'Monitoring'.
4) In the right pane, switch to the 'Logging' tab, make sure the 'Task Pane' is showed there.
5) In the 'Task Pane', click 'Configure Firewall Logging' under 'Logging Tasks', and then switch the 'log storage format' from 'MSDE database' (default) to 'File'.
6) Switch to the 'Fields' tab, click 'Select All', and then click OK.
7) In the 'Task Pane', click 'Configure Web Proxy Logging' under 'Logging Tasks', and then switch the 'log storage format' from 'MSDE database' (default) to 'File'.
8) Switch to the 'Fields' tab, click 'Select All', and then click OK.
9) Click 'Apply' to save changes and update the configuration.
10) Temporarily disable the Firewall service. To do that, please click Monitoring | Services tab, and then right click 'Microsoft Firewall' to choose 'Stop'.
11) Clear the current existing W3C logs. To do that, go to the log saving directory and clean any existing .W3C logs. By default, the logs will be saved to 'C:\Program Files\Microsoft ISA Server\ISALogs'. (Some MDF may not be able to deleted, that's normal.) You may backup them first and then delete them.
12) Go back to the ISA 2004 management console, and then Start the stopped 'Microsoft Firewall' service.
13) Reproduce the problem, stop the service, and then attach the resulting W3C files to the newsgroup.
14) Please also let me know the IP address of the testing clients so that I can filter the data.
Best regards,
Brandy Nee

While waiting for Brandy to reply to me, I discovered something interesting. If I disable ISA 2004's Web Proxy, everything works as you should expect (all be it a little slower).. Anyone got a take on that?

Ok, in my strive to find out why I am having problems with just one URL, I was attempting to make a transaction on this URL, and my firewall client reported it was unable to connect to the ISA server.
The Firewall Client is for ISA 2004. I have manually select the ISA server selected, with the server name. Just like I had with ISA 2000. The one thing I find funny is that instead of having the firewall client manager in the control panel, it's now in Programs (off the start menu). Is everyone elses like that? Is there a way in ISA 2004 to find why I am getting disconnected?

Hello Clevere,
Thank you for posting back.
I have received your email. After a long time research on your logs, I found there are some errors occur when the Firewall Clients pass the authentication to the ISA. Please try the following steps:
1. On the problematic client, temporarily disable the Firewall Client.
2. Close all IE windows.
3. Open Internet Options | Connections tab | LAN Settings button, configure the ISA's internal NIC as the proxy.
4. Launch IE to access that URL again to see if the problem still exists.
If this issue persists, please help to gather the following information:
1. You mentioned "disable ISA 2004's Web Proxy". Please fully give out the steps how you did that? Do you mean that you disabled HTTP Filter under Internet Security & Acceleration Server 2004\Yourserver\Configuration\Add-in?
2. Are there any error messages in the System event log and the Application event log? Please export the events into .evt files and then send to you.
I am greatly appreciated your time and cooperation. If anything unclear, please let me know.

Hi Brandy- Alright, this is odd.
I had to re-enable Web Proxy, for my network (I turned it off). I did they by Going to the ISA manager, clicking in Networks, right-clicking on the Internal network, and disabling Web Proxy.
With the web proxy enabled, I disabled the firewall client, and put in IE to use my server, at port 8080 for the proxy server.
I was unable to access the website in question. I turned on the Firewall Client, told IE to just "Auto matically detect connection settings" (so that it no longer used Proxy Server), and I could access the web site.
With the "Web Proxy" running, some sites seem to be having problems loading, but that could be because SBS is doing it's mid-week backup. This I can continue to test, I'll leave the Web Proxy turned on for now, and see how it performs during the day.
As far as IE goes, shouldn't I be able to tell it to use this proxy server, and be good to go? Do you need any logs?
There are no event ID's in the event viewer.

Hello Clever,
Thank you for posting back.
Please see my information below:
1. If you disabled the Web Proxy, whatever you enabled "Automatically detect connection settings", IE will not directly pass the request to the ISA. Instead, the Firewall Client will pass the IE requests to the ISA so it works.
2. To use "Automatically detect connection settings", we need to enable WPAD on the ISA. Please See:
309814 How To Configure Firewall and Web Proxy Client Autodiscovery in Windows 2000 http://support.microsoft.com/?id=309814
816320 How to configure firewall and Web proxy client Autodiscovery in Windows Server 2003 http://support.microsoft.com/?id=816320
Configuring DHCP and DNS for ISA automatic discovery http://www.isaserver.org/tutorials/Configuring-DHCP-DNS-automatic-dis.... html
We need to configure either on DHCP or on DNS for the WPAD record. For the DHCP way, we do not recommend do that since there are many known issues. For the DNS way, it needs to use the port 80 on the internal NIC. However, since the services on the SBS needs the port 80 on the internal NIC, we are unable to use DNS to configure WPAD.
As a conclusion, we are unable to enable "Automatically detect connection settings" in a SBS environment. If you really want to do that, you must use the DHCP way.
3. In your scenario, you should always manually set SBS' internal NIC as the proxy in Internet options instead of enabling "Automatically detect connection settings"
Hope the information helps. If anything is
unclear, please let me know.

Does that make more sense? I had to re-enable the Web Proxy for the internal network in ISA to do the testing you asked, Because I had turned it off. After I turned it OFF, I could no longer use "Use this Proxy Server" in IE, because the proxy server was turned off. So I had to reconfigure IE to just Automatically detect the settings, so it would work with the web Proxy turned off.
Does that make sense?
