ISA Server Routing (Chaining) Failure - HELP!!!
Desperate help needed here please!!
We have ISA 2006 Standard. Up til now it has been running perfectly...
This morning I came in to find that internet access was down, with the following error in the Alerts/Monitoring page of ISA configuration every 10 mins or so:
"Routing (Chaining) Failure"
Whilst in the Application Log at the same time, the following error appears:
Event ID: 14130. The Web Proxy filter detected that the upstream proxy server x is not available.
During all this, access to the web is unavailable.
Now i know the upstream proxy (our county's firewall) is working, as I have a single machine that connects ok (not via the ISA server). Checked all cabling, and all seems fine.
Various searches on the web has not really turned anything useful up.
Rebooted server but to no avail.
Can anyone help please?!?!
