Hi,
I keep getting the infamous generic error
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) (.Net SqlClient Data Provider)
when trying to connect (from my machine) to an SQL Server located at another machine within the private network.
I've already tried all the obvious and well-known solutions, with no success. From other computers using the same network I can connect without any problems, so it's probably something on my machine.
The weird thing is I work with that server for years and never had this problem, started a few weeks ago, without me changing any configuration. And even more weird is that I can ping the machine normally, the DNS is caching its name and after multiple sequential pings, it suddenly connects. Then, after some minutes of inactive, the error is thrown again.
Can anybody help me with that?
Thanks.
