Err Msg: Not Enough Server Storage is Available... (106167)

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..

If you are encountering this error message, try gradually increasing the value of IrpStackSize in order to find the minimal value which resolves the problem. Using a value that is larger than necessary can result in an unnecessary waste of system resources. Other factors can also lead to this error message. If problems persist with all legal values for IrpStackSize, restore IrpStackSize to its original value and another explanation for the error must be sought.

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.
