.Net 4.5 disables connection to remote database

 

After I installed .net v4.5 i ran into the following problem:

A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: SSL Provider, error: 0 - The wait operation timed out.)

The funny thing was that the error only occured when connecting to a remote SQL server. The bug is reported on  Microsoft Connect.

The work around for me was to remove non-IFS LSP installed Winsock Catalog Provider as described in the KB 2568167.

  1. Hello Lars,

    I have just installed Visual Studio 2012 and have the same problem as you have. I looked at the KB2568167, but I couldn't find Service Flag 0x20000 but only 0x20---.

    Do you have any suggestion to solve the problem?

    Thanks in advance

    Best regard,

  2. Michael,
    Could you please provide the dump from the command "netsh WinSock Show Catalog"?
