Hello,

I have two Compaq Laptop USB 2.0 computers, both running
XP pro. connected via an ethernet crossover cable. I
have attached two USB 2.0 external disk drives (FAT32)
attached to the server. I cannot access data on the two
external drives from the client computer. I can see the
shared drives and folders but I cannot open the folders
or expand the drive views. Both computer's have NTFS
formatted enternal drives which are not a problem and
work OK between the two computers.

Do you get any error message?
If so, what's the exact text of the error message?

Does it mention "not enough server storage to process the command"?
 
Hi Ron

That is the message I receive when I attempt to open a folder or expand the view of the drive

"not enough server storage to process the command

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)

The problem has been fixed. I did as you recomended and it was the IRPStackSize. I increased it from 11 and now all is working. I dohave Norton AV installed so that could have caused the problem

Thank you ever so much for you help.
