RE: ISA Errors

Hello Manfred,

Thank you for your suggestions. Most of the issues were resolved by getting
close to the spec that I had before moving the SBS box. Somehow there where
some conflicts with the Wireless Connection which was the new element. By
going back to 2 NICs and following the article that Kevin suggested, most of
the critical issues were resolved.

I don't care so much about Wireless Connection so I won't bother trying to
solve this issues with it. It would seem as if the ISA 2004 Server does not
like 2 NIC + USB Wireless configuration.

Finally based on your suggestion I installed the latest version of ISABPA is
installed on the ISA box. It is very helpful.

Hello Reuben

Thanks for posting here and also thanks to Kevin for the input.

If the issue persists after trying the steps suggested by Kevin, I suggest
you strictly follow this KB article to rerun the CEICW to configure the
network settings:

825763 How to configure Internet access in Windows Small Business Server
2003
http://support.microsoft.com/?id=825763

In addition, please check the following settings:

1. Check the TCP/IP settings on the internal NIC and external NIC:

a. Leave the Default Gateway of the internal NIC blank on the SBS.
b. Configure both the internal NIC and the external NIC to use the internal
DNS Service as the DNS Server.
c. On the DNS Server, create the DNS Forwarder to forward the external DNS
resolution requests to the ISP's DNS server.

2. Check the binding order:

a. Please open Control Panel -> network connections.
b. Click Advanced -> Advanced settings
c. In the adapters and bindings tab, make sure that the internal adapter is
on the top.

3. Do you have any customized publishing rule in ISA Server?

4. When did the problem occur? Did you encounter any performance issue on
the SBS Server?

In addition, please help to gather the ISABPA report:

Make sure the latest version of ISABPA is installed on the ISA box.
http://www.microsoft.com/downloads/details.aspx?FamilyID=d22ec2b9-4cd3-4bb6-
91ec-0829e5f84063&DisplayLang=en

Start a command prompt, change directory into:
C:\Program Files\Microsoft IsaBPA>

Run "IsaBpaPack.exe +Repro" (without quotation mark)

It will then ask you to press space bar when you want to start capturing
network traffic.

Try reproducing the problem.

After that please press space bar again on ISA to stop capturing network
traffic. It will package everything into a CAB file on the desktop. If the
file is larger than 5 MB, please let me know and I will arrange for a file
upload URL and password.

I hope the above info helps. Please let me know if anything is unclear.

Have a nice day!

Best regards,

| Hello,
|
| I'm getting a couple of errors on my ISA 2004 logs.
| 1) Failed connection attempt
| Log type: Web Proxy (Reverse)
| Satus: 12206 The ISA Server detected a proxy chain loop. There is a
problem
| with the configuration of the ISA Server routing policy. Please contact
your
| server administrator.
| Destination port: 80
|
| 2) 1) Denied connection
| Log type: Firewall Service
| Satus: A Non-SYN packet was dropped because it does not have established
| connection with ISA computer.
| Destination port: 80
|
| Any ideas on how to fix these.
|
| The website often does not load 1st time and then loads after pressing
| refresh botton. Others have said that the site is not working at all. Can
| these reports be related to the above errors?
