No authority could be contacted for authentication.

I have a developer that has a url that has been working fine.
Users access it via window authentication to validate users from other domains.

I have a trust built with this particular domain however when we test the login it fails with the error "No authority could be contacted for authentication"

Apparently it worked before but I have made no changes on the server and do not know why it no longer works.

If I log in with a different domain and username it works - just not this one particular domain. Any suggestions?

Sounds like a connection issue with that domain. Did you check the server logs for any clues?

I'm Certifiable, not cert-ified.
It just means my answers are from experience, not a book.

There are no more PDC's! There are DC's with FSMO roles!

It does sound like that however I am able to remote into servers at that domain.
We have VPN and Trust with that domain
I do not see anything in the event viewer that stands out and would be associated with this.

Have you tried running DCDIAG/NETDIAG to see if they come up with anything
