SQL Server (Microsoft SQL Server, Error: XXX) ★★★★★★★★★★★★★★★ SQL Server ConnectivityMay 16, 20077 0 0 0 This error message is the most frequent error message when connecting to SQL Server. You see this error message when you use SqlClient. In SNAC, the error message is slightly differently as follows: C:>osql -E -Syourserver[SQL Native Client]Named Pipes Provider: Could not open a connection to SQL Server [xxx].[SQL Native Client]Login timeout expired Basically, this error message just tell you that the client cannot make a connection to the server.
