SBS2008, Companyweb gives 404 pages at all workstations intermittently, may last 15-40 minutes, then starts working again. Event logs shows error EventId 3355; Cannot connect to SQL Server. np:\\.\pipe\MSSQL$Microsoft##SSEE\sql\query not found. Additional error information from SQL Server is included below. These seem to be preceded by EventID 3760; SQL Database 'ShareWebDb' on SQL Server instance 'np:\\.\pipe\MSSQL$Microsoft##SSEE\sql\query' not found. Additional error information from SQL Server is included below. The errors coincide with the 404 page errors, and the 3355 error comes up every 5 minutes until it goes away on it's own.
