USB HDs across LAN

[Rik Bean]

I'm running two machines and an HP Laserjet off the router. My notebook
is running XP Home SP1, my desktop XP Pro SP1. I can happily share
drives and folders from each machines internal HDs, and also their
external USB ZIP drives and 1GB flash drives.

What I can't get to work is sharing the external USB HDs attached to
the computers.

When I try to connect to them, having enabled sharing, I get an error
message:

"(drive) is not accessible. You might not have permission to use this
network resource. Contact the administrator of this server to find out
if you have access oermissions.

Not enough server storage is available to process this command."

As I'm logged in as an administrator, and the other drives are set up
the same way, I'm guessing that the last sentence is the critical one.
Has anyone got any thoughts on any tweaking I might do to get this to
work?

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:
