Can't access one system

[cmar]

I have 4 systems on a Win XP LAN. But one system, #1, cannot be accessed by
the other three systems, although from #1 I can access (copy or see files)
the other three computers. When I try to access a shareable folder on system
#1, get this standard error message:

Not accessible. You might now have permission to use this network
resource. Not enough storage available to process this command.

For the "not accessible" error, check that you only have one firewall
running. Some antivirus programs come with "Internet Worm
Protection" (like Norton 2005/06) which acts as a firewall or their own
firewalls. In that case, you don't want to have the XPSP2 Windows
Firewall running, too. If you have third-party firewall software,
configure it to allow the Local Area Network traffic as trusted. I
usually do this with my firewalls with an IP range. Ex. would be
192.168.1.0-192.168.1.254. Obviously you would substitute your correct
subnet.

For the "Not enough server storage is available to process this command"
error, here is the answer from MVP Hans-Georg Michna:

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 regedit.
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 with 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:

Antivirus Software May Cause Event ID 2011 (Q177078)

Malke,
Thanks for the detailed reply. I will try all of these.

Hi Malke:
You did diagnose the problem but fixing it is not so easy. The Event
Viewer does show the an event ID 2011 when I try to access the shared folder
on the system from the LAN. So it is an IRPStackSize problem.

The value is hexadecimal "f". I can change it to Decimal "15" but it
immediately reverts back to hexadecimal "f". I even tried deleting the Key
and recreating it but no luck there.

On one of the other systems on the LAN, the value is Decimal "15"; on the
other 2 systems, IRPStackSize is missing.
Cheers, CMA

I'm sorry but I don't know why the value reverts. Do you have Norton
products on the machine? If so, see what happens when you uninstall
them.
