I was having trouble getting D2R server running on my machine. Now, I know this worked in the past with no problems, but that was a few months ago. I think my version of MS SQL 2005 Express has been updated since then, but I wasn't sure.
Anyway, I couldn't get the thing to run. I kept getting the following error message:
The connection to the named instance has failed. Error: java.net.SocketTimeoutException: Receive timed out.
I was using the exact same configuration file as before so I was getting very frustrated.
map:database a d2rq:Database;
