Hi i have a SBS 2003 SP2 server running ISA 2000 and IIS 6.
Everything has been running absolutely fine up until yesterday when all of a sudden, we get the 503 - Proxy Is Busy error when trying to access the default website.
I have checked in the following Logfiles for any kind of hint as to what may be happening
I have recently had to apply a fix to the server because ActiveSync had broken because a hotfix caused the server to grab the Exchange push port during boot up, this is now resolved. HOwever a day later this occurred and i can't help wondering if tehre is a butterfly effect here.
