Last week we integrated to our new owner group.
We have created a new domain controller and a file/print server and DHCP and DNS all windows 2003 in VMWare. We also use a external Exchange 2003 server to host mailboxes.
With DHCP we have implemented a new ip range
All is working fine except it has become very very slow on the desktop pc's all running windows XP with all updates.
Example starting excel or word takes about 2:30 minutes or firefox browser (with proxy) starting takes about 3 minutes. Most of the time the pc freezes till the application is open again.
I have flushed the DNS and cleaned the prefeched folder with out result.
I have removed the pc from the domain and added it again no result.
Then i just disconnect the network cable and all was working fine and as soon as i connected the pc again same problem again.
The network guys from our new group analized the network performaces and this was normal nothing found the network was not used in that way that it could slow us down.
My idea is that this is something local on the pc, it work when you diconnect to lan. Maybe its keeping a cache or its try to connect to old stuff in the background.
I also have one machine new install from last week was connected to the old setup but not used much, this pc works fine in the new setup.
Programmas tested are:
Excel 2007, word 2007, firefox.
Does anyone know a solution to my problem?
Thanks in advance.
