Shadow copies causes server to hang ...

As stated at the subject of the post I have a windows 2003 SBS SP2 server
which has the behabiour stated. When shadow copies are created the whole
system freezes, mouse keyboard not responding and users get disconnected from
file shares and exchange mailboxes. I reprodused the error by manually
creating a shadow copy so this is the case. I have to add that this server
had its disks replaced lately and from a total size of 150 GB it now has a
total of 900 GB disk space as its only partition. System was moved with the
use of an imaging software to the same hardware ( only the disks on the raid
controller changed ) so it basically had no problem with the change except
this. Still its used space is atm 145 GB. Its an older system ( P4 with a
server board, 4GB of ram ) but it doesnt have any applications installed
except a well know antivirus suite so this shouldn't a performance problem.
Any ideas ??

Thanks in advance

Re: Shadow copies causes server to hang ...

First of all thanks for your response. I read the articles you suggested but
still, none of them is the case. I have no problem with the creation of
shadow copies, this part is working fine. its just that the system is
non-responsive at that minute ..... For the moment I have changed the
schedule so the copies are created after hours so it doesn't affect the users
but still an open issue....

I've been experiencing this problem for months now. I have no answer
as of yet. Part of the problem is the size of our shadow copy -
500GB. We scheduled it to run twice a day, but once in a while, it
hangs up on us. I've isolated that it hangs especially badly when
people are copying large amounts of data to the server at the time it
runs. People get knocked off the network/mapped share. It causes
Outlook to freeze. Have you heard any other solutions?

One other thing - when someone is performing a search, and selecting
the large drive/folder, the system hangs as well. We've seen similar
behavior with Google Desktop. It might be a controller or I/O
problem, I'm not sure...
