This issue has me completely stumped. About 3 weeks ago a number of our computers on our network have started experiencing slow application loads.
The problem we experience is applications will load very slowly on these computers and will actually hang for about 15 to 30 seconds. The application will always eventually work. It is like a process is hanging or busy. If you launch other applications while one application hangs, that new application launch also hangs. Example, launch Application A, then run a cmd. The command prompt window will not appear until application A starts responding.
I have disconnected one of the problem computers from the network and try to test. The problem still exists but the hang/pause times are much less.
At first I thought we had a bad switch so we replaced our switch with a new switch. No luck. I have isolated the network down to only one of the problem computers and the issue still exists.
We have spent a week thinking it is a virus issue and have done ton's of scans, malware searches etc. We cannot find anything that we can say we have a virus or some other type of infection. It is possible we have one bad computer causing network issues, but not all the computer have this issue. Half of the workstations all work fine.
Environment. This is a windows environment running windows 7 on all workstations. We have VMWare services running all on Ethernet cat 5. The new switch is a Netgear prosafe Gigabit smart switch model GS748T.
None of our servers exhibit the problem.
I would appreciate any thoughts on what direction to head in to help trouble shoot this issue.
