We started getting a proxy chain loop detected error today in ISA server 2004 sp2, nothing has changed, it just comes out suddently after a scheduled reboot.
we have 2 independent ISA server for different department, only one of it(Server A) having problem while the other one (Server B) is function normal after this schedule reboot.
I've check the routing table and network setting, both server is exactly the same.
One thing is very strange, server A originally can browse web page, and after I make it to use itself as the proxy to test for this issue, it can;t do a browsing even though I rollback to not using proxy, until I set it to use server B as the proxy.
I've also check the configuration-> networks, the setting is the same as server B.
What can I do to bring it back to normal?
Thanks!
