Peer to peer problems

Hi I have just set up a peer to peer home network for a client.  He has a desktop connected via ethernet  to a netgear wireless adsl router, and he has two laptops connected wirelessly.  This is fine I have shared the printers and all the files he wants shared are available.  But he has a freecom usb 2.0 external harddrive connected to the desktop that he wants shared, but everytime I try to share it, it appears in the shared folder with a little red question mark next to it and when you double click on the drive it states that it is unavailable but you can access it from the desktop ok.  Any one have any suggesstions?   He is running Xp pro sp2 on all three machines

wich has helped me to solve this previously.


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.
