Shad, Re: > The log files show the 10054 and 10053 errors > around the times that the service spikes. Are those errors triggered by any particular user, IP address, browser, request for a particular page, etc... (look a bit farther back in the logs). I would have to agree on the network issue as being the probable cause. Leave that to others who know more than I... hmmm... are all 7 on the same network and branch or share something else in common? Can you move one closer to the internet and see what that does? (just a few ideas...)
