This is my situation now..
I have a Standard server (STDSRV) and an ISA server (ISASRV). They are connected together thru a hub and the ISASRV is connected to the Internet Router. My client PCs are all connected to the STDSRV. The client PCs are able to access the internet. But recently, my ISASRV crashed and I'm forced to reformat it. No backup was done, so I need to reconfigure the entire ISASRV.
But after I've completed my configuration, my STDSRV can't ping to the ISASRV. After I disabled these four services namely: Microsoft Firewall, Microsoft Web Proxy, Microsoft Scheduled Cache Download and Microsoft ISA Server Control, my STDSRV is able to ping to the ISASRV.
Even if the two servers are able to ping each other now, my STDSRV still can't access the internet. When the 4 services are up, I tried pinging the STDSRV from ISASRV and Router from ISASRV. I got a "Destination Host Unreachable" msg.
Any suggestions would be greatly appreciated. Thanks!
