Message: SQL Server does not exist or access denied.

Receiving the following error:
Message: SQL Server does not exist or access denied.
Source: .Net SqlClient Data Provider
at System.Data.SqlClient.ConnectionPool.GetConnection
(Boolean& isInTransaction)
at
System.Data.SqlClient.SqlConnectionPoolManager.Get PooledCon
nection(SqlConnectionString options, Boolean&
isInTransaction)
any clues please?
Check the Datasource property of the connection string to make sure the
server name /instance name is correct - you can check by creating a new text
document, renaming it to test.udl, opeing and setting the connection
properties, then closing it and open in notepad.
Make sure you can ping the server.
Make sure the DBA's or network dudes haven't closed port 1433
