Office communicator

We have enabled approx 440 users but this is the first with the problem, he receives below error, we have verified that we can see him in OC server and also there is a SIP address on this user as all others

"Cannot sign into Communicator because this sign-in address was not found"

Davorin, your suggestion is in regards to making some DNS changes or Firewall changes (would this be on Client or OC server)

Rancy, I have to try some of your options as i havent tried them as of yet

Domain should be listed on OC server, DNS records on DNS server hosting used domain.

BUT it looks I have misread your question. Now I see you have problems with a single user.

Have you tried to use another computer to sign on this user.
DNS settings are the same on this client?
