Hi All, I have a few sql 2008 servers on windows 2008 and except to one of them I am unable to connect to these instances from my local machine(which is sql 2005 sp3 on winXP) . I also tried from my laptop which has sql 2008 installed on it but with no luck. Here is the message I get:
Since there is no trust between the two domains I am using sql logins to connect to the servers in question. And here is what I tried so far: I check 1433 port is open, I turned on sql browser, I checked the firewall is not blocking. BTW I am not also able to connect to these 2008 instances from 3rd party tools that I use to monitor my servers. Please let me know if you have any solutions. Thanks,

I asked the network and server team to turn off the firewall briefly so that I can try connecting and rule out if it is not the firewall. I was able to connect to the instances. That was strange because port 1433 was already open and mycoworkers are connecting to the instances and the problem happens only with my machine. Once I know for sure it has something to do with firewall I asked the server team to reconfigure their firewall. We created an exception and let SQL server instances listen to requests that comes from my IP and everything worked just fine.

What service account is running SQL Server?
For one instance SQL server is running as local system and other services including sql browser are running as NT AUTHORITYLOCAL SERVICE. The other instances in question are running under NT AUTHORITYLOCAL SERVICE.
Have you checked the SAC utility?? Make sure it is accepting connections for the engine and browser.
Yes I checked and it was configured correctly. Thanks!
