I have just stumbled upon this same problem myself (same exact error). My application which uses these DSN's I have created some time ago, do work, because I have the connection timeout set with no limit. However if I go into the control panel and try to test them I get this error. This poses a problem for me because I can't add any new DSN's for the server.
Just seems like SQL is taking a looong time to respond.
Any other ideas to trouble-shoot this problem?
