I have problems connecting computers running Windows 7 to a database SQL Server 2014 Express intermittently.
It happens that, intermittently, I can not connect to the database that is on a Windows 2008 R2 server.
If I restart the computer, works again, but only for a few minutes, sometimes hours.
The Firewall of my computer is turned off. Windows Firewall is turned off.
- The server is Windows Server 2008 R2 Foundation
- Firewall Ports TCP / IP and UDP 1434 1433 allowed
SQL Server Express:
- Unlimited Connections
- Allows remote connections
- Timeout remotely query: 600 seconds
Machines with Windows XP have no problem with this issue.
