I'm just looking for some suggestions of possible causes for losing connection to our server periodically. We just brought our whole IT infrastructure in house about 6 months ago. From day one we've been losing connection to the server (ie. our offline files folder kicks in, lose connection to Exchange, can't access network folders) around the same time every day. Between 11am and 12pm. We have replaced the switches, assuming first they were the issue, and we were okay for about a week, but then started to experience the same problem. Next we analyzed what is happening between 11am and 12pm on the network, the only things are a few scheduled tasks for back ups. We've stopped the scheduled tasks for now, but still are being disconnected. I'd appreciate any thoughts as to possible culprits.
Software/Hardware used: HyperV, Server 2008, XP, Cisco, 3com
