Does this stack exchange question help? https://dba.stackexchange.com/questions/57455/sql-server-connectivity-issues What is going on with the SQL Server when you try to attempt to connect? How are you attempting to connect? Through SSMS? An application?

It could be a limit on connection pooling. It also could be too many open connections. Be sure your apps are closing their connections when they're done. [Here's a good blog post][1] on MSDN for troubleshooting this error.
