This is my issue:
We have SBS 2003 R2 installed, ISA 2004. SBS box configured for OWA.
WHat happens is that we get intermittent connectivity to OWA. Trying to connect to OWA produces two to three errors:
Error code: 12206
Background: The page you requested could not be reached
Error Code: 500 Internal Server Error. The target principal name is incorrect. (-2146893022)
I refresh Internet explorer 4 to 5 times and then I connect to the OWA page and I am able to login no problem.
This is very strange and frustrating. We have tried several recommended changes:
Assigned a host header to match the https publishing rule is ISA, this did not help.
Put a host file on the sbs box itself to resolve the OWA path, this did not help.
this appears to be some sort of ISA loop issue but we cannot get it fixed. If anyone has had the same issue and knows the fix or can point us in the right direction it would be appreciated!!!
