Unable to access network shares after changing name of host comput

Hi
I have installed a new computer on a peer to peer Windows XP network, used
simple file sharing, NTFS format on disks.
All sharing worked perfectly could access any share directory from other
machine on network.
I then changed the name of the computer in control panel.
You can see the computer and its shares but this immediatley stops access
from the network and you get the message "XXXXX\\Dir is not accessible. You
may not have permissions etc" and another line "Not enough Server storage to
process this command"
On the srver computer in the Event Viewer / System it creates an error
report Event 2011 with the details "The servers configuration parameter
"IRPStacksize" is to small for the server to use the local device. Please
increase the size to 15" I looked at the MS Help and support and they advise
how to increase it. however neither computer has the "irpstacksize" in the
registry at the location.
I have tried resharing the drives etc but nothing except reinstalling
Windows will fix it.
Any help would be appreciated as I am out of ideas.
Thanks
PhilipJack

The IRPStackSize problem is usually caused by a program like Norton
Antivirus. I haven't seen it happen from just changing a computer
name. Did you change anything else at the same time?

Is this the MS advice that you found on changing IRPStackSize?

Antivirus Software May Cause Event ID 2011
http://support.microsoft.com/?scid=kb;en-us;177078

That article says to look for the IRPStackSize value in this registry
key, and to create the IRPStackSize value there if it doesn't already
exist:

HLM\System\CurrentControlSet\Services\LanmanServer\Parameters

The server computer is the only one that needs the registry edit.
