Hi,
Thank you for posting in SBS newsgroup.
From the description, I understand the issue to be: you can not pingexternal IP from client computer and you will get error 404 if you check
"Use a Proxy Server for your LAN" on Internet Options when you access
internet. If I have misunderstood your concerns, please do not hesitate to
let me know.
We can try the following steps to see if it helps.
I. On the client computer, please make sure you have firewall client
software installed and set your SBSserver:8080 as the proxy in your IE.
II. Check the configuration on SBS and client computer:
On SBS server:
External NIC:
IP: assigned by your ISP or your hardware router
Gateway: your ISP or your Hardware router IP
DNS: SBS INTERNAL NIC IP as the only entry
Internal NIC:
IP: Fixed IP
Gateway: None
DNS: SBS INTERNAL NIC IP as the only entry
In the DNS console (dnsmgmt.msc), right click your ServerName and click
properties. In the Forwarders tab, your ISP DNS server IP should be
inputted there.
On workstation inside your SBS local subnet
IP: Assigned by DHCP on SBS
Gateway: SBS internal NIC IP
DNS: SBS INTERNAL NIC IP as the only entry
III. If the problem persists, please use administrator log on to this
workstation and please confirm if you could access internet correctly.
IV. If it does not help, please rerun CEICW so that it will help us to
configure ISA 2004.
1. Open Server Management, click To Do List, and then click Connect to the
Internet to launch CEICW.
2. On the Wizard, click Next until you see Firewall page.
3. Click to select Enable Firewall, and then click Next.
4. Select all options, and then click Next.
5. Click to select "Allow access to only the following web site services
from the Internet", and then select the websites that you need such as
Windows SharePoint Services intranet site, and then click Next.
6. Click Create a new Web server certificate and input your FQDN as the web
server certificate on Web server name column and then click Next.
7. Follow the instructions to finish the rest steps.
For detailed information, you may refer to the KB article below:

2003
http://support.microsoft.com/?id=825763
If the issue still occurs, please help me collect the following information:
1. Collect the 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) Please send these files to me at v-crinal@xxxxxxxxxxxxxx
2. Please also help to 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 (initiate an SQL access), stop the service, and
then gather the resulting W3C files to me for analysis.
If you have any questions or concerns related to this issue, please do let
me know.
I appreciate your time and look forward to hearing from you.
Best regards,
Crina Li (MSFT)

| Problems with SBS 2003 Premium SP1:
|
| 1. Cannot ping any IP address outside the SBS domain from a client
| computer. Ping to external IP addresses works fine from the SBS server.
Is
| this the intended SBS default? How do I change Group Policy and/or ISA
to
| allow client computers to ping outside the SBS network?
|
| 2. In order for any client computer to access the Internet, must bypass
| Proxy Server by unchecking "Use a Proxy Server for your LAN..." in
Internet
| Explorer Connection LAN Settings. If Proxy Server not bypassed, get
Error -
| 404. Any ideas?

| Gotta go. Another day, another dollar and always more Microsoft service
