Timeout in connection to a SQL Server instance in LAN

  • 772

From one windows 7 machine I cannot connect anymore to any sql server instance that is in LAN and in same domain of this particular machine. I cannot connect from Management Studio, but also from any client server application.

I use sql serer autentication and this has always worked until a few days ago I installed some vpn software. Now I uninstalled it anyway the problem persisted.

I tried to do from the command prompt ipconfig /fulshdns (I did "Run as administrator") but it didn't help.

What can it be? Is there a place where I can manually check?

  1. Perhaps your TCP/IP stack got mangled. As an administrator, from the command line try:

        netsh int ip reset C:\log.log

  2. Is it possible that your VPN software is blocking port 1433 which is used by SQL Server?
