The semaphore timeout period has expired

Hey @anilsharma80 you don't happen to remember if this was ever resolved and what the solution was do you?
I've got the same situation with a client. When I try to run SSMS from inside their network and connect to a datamart instance, I get the same semaphore timeout. I suspect they have restrictive firewall rules...
Thanks
Craig
make sure TDS protocol is open on your firewall. It helped in my case
Hi @anilsharma80 ,
Is the firewall turned on in the server that is installing SQL Server? If so, please check that if you have added the TCP port and UDP port (1434) in the inbound rule of the Windows Firewall, and you can verify TCP port in SQL Server Configuration Manager.
