Hi all, complaints of the new year!
We are running SBS 2011 as out office server. Got 12 PC/Laptops connected to it.
SBS is fully patched and well looked after.
Installed on the SBS box too is an SQL database.
Past two weeks we have on our users pc "lost" connectivity - Exchange gets disconnected and the SQL throws ODBC errors. Some instances the shared folders dissappear and we can only view the redirected folder.
A couple of seconds later - all back to normal.
RDP connection to the server throws out a protocal error and disconnects.
Replaced the switches.
Replaced the netgear firewall.
Replaced the network card
Turned off Power management on the NIC.
Ran Fix Your network. (Complains that it couldn't configure router - but the relevant ports are opening and working)
No errors in event logs other then the ongoing "safe to ignore" ones.
Other then that everything working 100% - just we loose connection. I done seem to loose connectivity more often the more we load it. Like playing movies from the server etc.
What am missing??
Or send me in the right direction on some network tools?
