Strange network problem...
Ok so 8:30 this morning I get a call from school to say can I get in early because Ofsted are in (which means all the teachers are in panic mode) and the network is running really slowly...
So I arrive at school and the network is definitely on a go-slow... start-up of computers takes ages at the applying computer settings stage and then when users try to login this takes ages as well. Once logged in any apps that run from the network are taking stupid amounts of time to start...if they start at all.
Loading the intranet via IE is as slow as dial-up internet at it's worst.
I spend the morning trying to find a cause for this and discover that some machines are still ok and there are no errors logged on the server that would tell me what's wrong.
At about 11:30 I try logging in on a computer and find that all is well again...same thing on all the computers that were having trouble!
Now although I am very happy that the problem went away I would still like to know what happened.
The server is running Windows Server 2003 and all the clients are XP Pro. The main switches are Netgear 1Gb.
Does anybody have any ideas what could have gone wrong and are there any particular tools/methods that would help in diagnosis if the problem comes back?
