Everythings Just Stopped... XP Clients, W2k3 DC ridiculous logon times...
I think this is my first post here, but i have watched for a while.
Anyway, I'll cut to the chase.
Last week was the first day back for our kids at our primary school. During the holidays i had re-imaged Every machine in school, upgraded the Nics and memory etc...
Everything seemed fine untill the first day back. Despite having every machine up and installing software etc the day before (which was hunkey-dorey) everything just ground to a holt as soon at the teachers and kids hit.
FYI The users have redirected folders, no roaming profiles.
The XP clients were sat on "Preparing Network Connections" or "applying Computer Settings" for nearly 30 minutes before the logon dialogue appeared.
Then logon would take a good 20 minutes too.
When you were in there was problems with shares, they would just come and go.
The DC its self was a 40 minute wait to logon aswell. and once you were in is was dog slow. Yet memory usage was normal, network traffic and processors were next to nothing.
The Raid of this server was for some reason rebuilding its self. I sort of put it down to that, and next day everything seemed normal again.
But today the same thing.............
When i got the call it was a 20 minute logon to the DC, i rebooted it and could logon as normal, 5 seconds or so but after an hour it all went to pot again.
A friend thinks its a DNS problem as of late we have had a few cases of Machine names not resolving to the correct IP's
The Clients are XP SP3 and W7 SP1
2 DC's running DNS and one of those does the DHCP.
After looking around on here i have tried adding the domain name to section 15 In the DHCP settings
Deleted all the client entries from both DNS servers. Added the second DNS to the DHCP Settings
Changed DHCP to force DNS updates if the client doesnt request them.
Scavinaged Both DNS's for stale records.
I will add to the note that the DC has alot of DCOM errors in the Event viewer which i cant get to the bottom of. Error 10016. Could this be to blame?
Unfortunatly, i cant seem to wake any of the clients remotly for some reason so i dont know if any of this has helped.
