Hi,

I used to connect to SQL Server 2005 with SQL Management Studio 2005 locally and through VPN no problems under win XP pro. Since fresh install of vista business x64, I can connect locally no problems, but over the vpn I get the following error message.

TITLE: Connect to Server
------------------------------

Cannot connect to 192.168.0.100\ENERNET.

------------------------------
ADDITIONAL INFORMATION:

A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1)

I tried multiple ways to connect, (FQDN, NetBios ect...) I won't connect. Perhaps my apps using SQL Server run no problems  over the VPN.

Any one has a clue?

No firewall on Server, ports 1433 & 1434 open on router, (connected through vpn on PPTP)

It was the firewall of my client machine (vista) that caused the issue
