Error establishing socket to host and port: XXXXXXXX:1433. Reason: Connection timed out: connect

I have recently move to a new 2003 WIN server running IIS 6.0. Last night the Coldfusion server crashed and when I was checking the c:\Coldfusion\runtime\logs I came across the following error.

10/11 18:32:01 Error [jrpp-9620] - Error Executing Database Query.Timed out trying to establish connection The specific sequence of files included or processed is: D:\website_directory\index.cfm, line: 838

Timed out trying to establish connection

Would increading the Maximum number of simultaneous Template requests from 10 to 20 resolve the issue? This is the first time I have seen this..
