SQL Server Connection Problems

Question

I have one server out of three which cannot connect to our sql server 2000 using the FQDN but can connect using the non FQDN. None of the other servers are having this problem.

This problem occurs under ADO connections to a SQL Server 2000 database.

The database has encryption turned on. I don't want to turn it off.

Does anyone have any ideas of what to look at?

Notes: You can ping or telnet to the sql server using both FQDN and non FQDN. The other two servers are working fine and all servers are on the same subnet. All the servers are running Windows 2000.

Answer 1

What error do you get?

Probably the certificate used to encrypt the connection (the server SSL cert, possible self signed) has the simple, non-qualified, name of the machine as subject. The client thus rejects the cert when it attempts to connect, breaking the connection.
