Hi,
I have a 120 Gig Western digital external USB HD attached to my system. I
can access the drive fine from the computer it is attached to (sharing is
enabled). The problem starts when I try to access the drive from the
network. I can see the drive but when I try to access I get the typical
message "you may not have permission to ..." but I also get at the end of
the error message, "not enough server storage space ... ".

Thanks for any thoughts.

This error indicates that you are falling foul of the IRPStackSize bug.

The problem is on the machine you are attempting to connect to,
not the machine where you see the error message.

On the computer you are attempting to connect to,
Check the event viewer for an event ID 2011.

Usual fix :
You need to fix a parameter called IRPStackSize

On the computer you are attempting to connect to,
Set the IRPStackSize back to the default (15 ).
Perform the following steps:

1. Start the registry editor (e.g., regedit.exe).
2. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\lanmanserver\parameters.
3. Double-click IRPStackSize
(or if this registry setting doesn't exist,create it of
type DWORD and ensure the case is correct).
4. Change the base to decimal, set the value to 15, and click OK.
5. Reboot the computer.

Norton AV is usual suspect for breaking it.

There's a KB article about this, too.
You may have missed it, because it's applicability has not been updated to
include XP:
