This one has baffled me, I have just upgraded Symantec Corporate AV from 8.6 to v9.0 on our Windows 2000 Server SBS + Exchange 2000.
After sorting out several faults with the SAV 9 installation, I find I can no longer download from FTP sites, although HTML & MAIL work OK.
In event log I find I now have a Web Proxy Error ID 14120 – Conflict between the Routing Table & the LAT, but I can’t see one.
Another article says that I will get this error if I only have one network card in the server and ISA is installed in integrated mode.
Well this is all true, we do only have one nic in the server and ISA does seem to be in Integrated mode, trouble is I have never set up ISA, it should not be active, could SAV 9.0 have set it going some how ? Symantec say it is nothing to do with their software, but it?s funny how it was working perfectly before I upgraded the SAV !
Another error in event log says that the DNS that the server was forwarding to, did not support recursion or something similar and I had to turn off DNS forwarding to resolve that.
I am well out of my depth here, but I feel the fault does lie with the DNS addresses more than with ISA, possibly, maybe ?
I really could do with some help here.
