A1 Consider checking general network connectivity (ping the server from the workstations). If network connectivity is present consider verifying / checking the DSNs in use (verify protocol settings, etc., and test the connection) and / or use the MDAC compatibility checking tool to assess MDAC component status. See: http://www.microsoft.com/data/download.htm#CCinfo
http://download.microsoft.com/downl...XP/EN-US/cc.exe|||Ping the server OK
Already checked Client Network Utility and Server Network Utility. Both use TCP and NamePipe.
Run MDAC check already.

ODBC still don't work.
