we have serverA (sql box),
server B (application server)
server C (IIS server, application servr)
Server D (application server)
getting error from Server C - ERROR: (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
no other server throw this msg...
when restart IIS @ server C issue solved.
i do't see any longrunning, blocking issue on sql server , & i configured Replication ( act as publication& distribution) do't see any replication command pileup in distribution.
-------
i thought , network may down between Server C to Server A
or any IIS issue happen on Server C ? how to check this?
