I disabled the built in domain administrator account in Active directory and now users cannot connect to a very important the SQL server application. The application tries to establish a server connection on port 38113 and fails. When I run the application locally on the server it fails with the error:
"socket connection failed (error code 10061)"
If I re-enable the ID and reboot the server, it works again...If I then disable the ID after that reboot, it continues to work untill the server is rebooted again, then it stops working. I suspect a connection string needs to be modified somewhere but I don't know where and how to change it.
