As shown in other documentation, I map drive letters to use with Jcopy via the "net use" command. Recently, one of the computers on my network would no longer run the cmd file successfully. I got error messages like these after each "net use" command:

"System error 1130 has occurred.
Not enough server storage is available to process this command."

After Googling on both "not enough server storage" and "system error 1130", I found numerous references. Many suggested the error was caused by Norton's Anti-virus software, but it is not installed on the misbehaving computer.

I tried several solutions before I got one that worked - I had to edit the registry to change the value of IRPStackSize. Here is what I used, which I have copied from a post on the microsoft.public.windowsxp.general newsgroup


If you are referring to the value IRPStackSize, it needs to be 15. Here's my usual lecture on the topic:

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.


Just in case that does not solve the problem, another post by a Microsoft MVP suggests that you may have to keep increasing the value until you achieve success:

"The default is 15.  The instructions say to start at the current value (or the default if no current value), and increase by 3, until reaching a maximum (supposedly 50).  Don't give up at 18, or 21, or whatever.  There's no one solution, it's trial and error, unfortunately.  And each trial is different."


As a postscript, I reinstalled Windows XP early in November 2005. I also switched to using Acronis True Image and Acronis Disk Director.

When I tried to run Jcopy, I got the "server storage" message. I first increased the value of IRPStackSize to 15, but that was not enough. I had to increase it to 20 to successfully use my mapped network shares.

I recently got this "server storage" message while trying to map a drive to another PC on my network. Based on this post, the solution is to increase the IRPStackSize on the target machine (where the drive exists).
