Just recently we have been experiencing some major performance issues with our computers and network. Here is what I got...
We have a 25+ Windows Server environment with 2003, and 2000 servers. We have a DHCP server, DNS, Domain Controller, Exchange 2003, file server, SAN, multiple Cisco switches and so on. All our computers run Windows XP Pro.
The issue we are having is this....
In the morning when we all go to work, our computers just lock up and freeze. It's not just one person, it's everyone. For instance on my computer; if I open op "My Computer" it will just sit there and do nothing for about 5 minutes. Or if I click Start > Run it will just sit there. Or if I hit the task manager, nothing.
This only seems to happen in the morning for about an hour or two.
We do have mapped drives on our computer. I checked the performance of all the server that the mapped drives point to, and everything seems to be okay. Also during this problem when I can get the task manager open, CPU usage is low, Networking usage is low, Memory usage is low.
We do not run any roaming profiles on the network.
I have checked the GC's event log, and could not find anything that stands out.
What should I check? I'm trying to think of the cause of this issue, but I'm not really sure where to start.
