ok, I was recently very naughty and due to un-favourable circumstances I installed exchange 2010 to a server that was already running SQL. Not ideal, but the 3 month plan will correct this situation so yeah.

The problem however is that since this time, I'm getting periods of network dis-connectivity, its almost like clockwork, at 2 mins past each hour I get a network dropout, pings going out from the server to the local network return first a high ping time then request timed out (See below)

The network card itself does not report a drop, the server is about 2 years old, it has 2 x on-board networking in a teamed configuration, I have tried disabling each in turn.

I have checked all the scheduled tasks I can see and cant find anything set per hour.

We don't believe we had this issue before exchange, but don't take this and conclusive.

Server: Dell PowerEdge R410
Network: Broadcom BCM5716C NetXtreme II GigE
Network Teaming: Broadcom Advanced Control Suite 4 (Version 15.0.30.0)
Windows: 2008 R2
Exchange: 2010 Standard


The problem most noticeably shows with our SQL enabled application.

Any help would be great

Thanks
