Unable to begin a distributed transaction

Question

I\'m trying to run SQL against a linked server, but I get the errors below :

BEGIN DISTRIBUTED TRANSACTION
SELECT TOP 1 * FROM Sessions


OLE DB provider &quo         


        

Answer 1

Apart from the security settings, I had to open some ports on both servers for the transaction to run. I had to open port 59640 but according to the following suggestion, port 135 has to be open. http://support.microsoft.com/kb/839279
