The information in this article applies to:
  • Microsoft Windows NT operating system version 3.1
  • Microsoft Windows NT Advanced Server version 3.1
  • Microsoft Windows NT Workstation versions 3.5, 3.51, and 4.0
  • Microsoft Windows NT Server versions 3.5, 3.51, and 4.0

When you access shares on a Windows NT server from a Windows NT client and the IRPstackSize parameter is set too low on the server, you may receive the following error message: 

   Not enough server storage is available to process this command.

MORE INFORMATION

The registry value IRPstackSize, which may be listed at HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services\ LanmanServer\ Parameters defaults to 0x4 if the value is not explicitly present. Valid values range from 0x1 to 0xC (1 to 12). Depending on the hardware configuration of a specific machine, the default value may not be large enough for the Srv service to properly administer shared directories on some of the physical drives. You may see one or both of the following event messages: 

   Event ID: 2011  Source: Srv
   The server's configuration parameter "irpstacksize" is too small for
   the server to use a local device.  Please increase the value of this
   parameter.


   Event ID: 0
   Source SRV
   Description:  Description for Event ID 0 could not be found.  It
   contains the insertion string \device\LanManServer
You may receive one of the above error message when a Windows NT client tries to access certain shared directories on such a server.

When a Windows for Workgroups client tries to access the same shared directories, the following message will be generated: 

   Path not found.
To increase the value of the parameter when it is not already present, go to the key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ LanmanServer\Parameters. The value of IRPStackSize defaults to 0x4 if it is not explicitly present. If the key is not present, choose Add Value in the Registry Editor. The Value Name should be IRPStackSize and the Data Type is REG_DWORD..

WARNING: Using Registry Editor incorrectly can cause 

         serious, system-wide problems that may require you to
         reinstall Windows NT to correct them. Microsoft cannot
         guarantee that any problems resulting from the use of
         Registry Editor can be solved. Use this tool at your own
         risk.
