Sever 2008R2 Network Issues

I have a server 2008r2 on a Dell 1U Piece of Hardware. For some reason RDP and VNC connections constantly drop and eventually will not let me connect again until I restart it.  When I do a constant ping to the server it seems normal with the occasional 6 to 8 MS latency but not very often. I see nothing in the logs to indicate why its doing this. Any feed back on a place to start looking would be helpful..

since the ping is ok then there is no network / connectivity issues. did you tried to turn off the firewall / antivirus / internet security on it till you test? maybe they are blocking it.
also. if you have hardware firewall, do you have access to the ports?

I haven't messed with the windows firewall and the RDPs are inside the network so not a external firewall issue. We use ESET for security and and I reviewed the logs and didnt see anything..

Hi OP

does "perfmon /rel" give any more in-site?
the client connecting to the server is it on the same LAN?
I would suggest if you are on site try setting up a Wireshark capture using mirror ports  and seeing if the loss in connection is down to TCP stack falling over or a windows feature.
also its worth noting down not all Dells will have up to date drivers and BIOS is some times forgotten especially if you bought it from resellers  and not direct.
