I'm running a Windows 2003 SBS Server with ISA 2000 Server as our firewall. I had a connectivity problem which turned out to actually be a loose cable, however, in the course of troubleshooting, I re-ran the Internet Connection Wizard as I suspected adding a modem to the box had accidentally changed something. I ran the Wizard without changing the firewall settings, however, apparently I broke something.
My client PCs can access the shares on the file server and client email is getting through to Outlook clients. However, whenever I try to access the web via a browser, or try to use an FTP client, I get a authentication popup window saying: 'Connecting to 192.168.232.1' and asking for a username and password. Nothing I enter gets me through.
Everything ran correctly before, but apparently the ICW changed something on the server and now the clients are running into Proxy Authentication errors.
Under a client PC's Internet Settings|Connections|LAN Settings, they have a checkbox checked to use a proxy server with the address 192.168.232.1 and Port 8080 and the bypass box for local addresses is checked. This worked before, but no longer does now that the ICW has changed something.
I'm stuck trying to troubleshoot this and am not sure where I should be looking. Can anyone offer me any assistance?
