I'm trying to get a network with ISA 2004 to allow us to use our remote supports tools, namely GoToAssist and uVNC.
I have use the ISA mmc to monitor the server I am using for testing and I can see the request attempt to connect over port 80 and then 443, both are being denied a connection by the Web Access rule. We didn't configure ISA on this site, it is something we inherited. I've looked at the Web Access rule and I can't see anything in there that would block access apart from it relying on a group of users for access. The account I'm logged in as is in that group.
The log files for the Firewall and Web Proxy don't give any further details.
I'm guessing the issue is that the remote support tools don't have an option to use a proxy, but I thought they would just use the default connection details of the server.
Any help much appreciated.
