Unable to share C: drive/files in Windows XP Pro

Hi,

At the office we have approx networked 10 computers running windows 98SE.
Lately, we have been upgrading several of the computers and installing
Windows XP Pro.

The first computer I upgraded worked fine. I was able to share the C: drive
and was able to access the computer's files from all the other computers on
the network.

Since then I have upgraded two other computers to Windows XP. For some
reason, I'm not able to access these computer's C: drives from other
computers on the network.

From a Windows XP Machine I get a message ....

"\\computer is not accessible. You might not have permission to use this
network resource. Contact the Administrator of this service to find out if
you have access permissions.

Not enough service storage is available to process the command."

From a Windows 98 Machine I get a message....

"\\computer is not accessible

Not enough memory is available.... Quit some programs"

As far as I can tell, the settings on the last two computers are the same as
the first XP machine. I shared the C: Drive and gave "Full Access" to share
and modify files.

I even turned off the firewall with no luck (The Firewall is turned "On"
with the XP computer that works.)

I think the problem is in the permissions but don't know how to resolve the
problem.

Any help would be greatly appreciated.

Thanks

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:

Antivirus Software May Cause Event ID 2011 (Q177078)
http://support.microsoft.com/default.aspx?scid=kb;EN-US;177078
 
Thanks.... That solved the problem.

You called it right when you said that Nortons AV likely caused the problem.
The two computers experiencing the problem had Nortons installed.. The one
that was fine didn't.

Doubt I would have ever figured it out.

Thanks again
