- 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.
-
- SYMPTOMS
- ========
-
- The following error may occur when printing using the Hewlett-Packard
- (HP) print monitor over the DLC protocol:
-
- The server's configuration parameter irpstacksize is too small for
- the server to use a local device. Please increase the value of this
- parameter.
-
- Irpstacksize specifies the number of stack locations in I/O request
- packets (IRPs) used by the server. It may be necessary to increase
- this number for certain transports, MAC drivers, or local file system
- drivers.
-
- Another indication of this problem is that the status of the printer
- may be listed as "not available" in Print Manager.
-
- RESOLUTION
- ==========
-
- To correctly configure irpstacksize, use the Registry Editor
- (REGEDT32.EXE) to edit the following registry key:
-
- HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\
- Parameters
-
- 1. Create a new value called "irpstacksize." The value must be of type
- REG_DWORD.
-
- 2. The default value is 4. Increase the value by 1 until the error
- message stops. The range is 1 to 12. Each increment costs 36 bytes of
- memory per work item (number of work items multiplied by 36 bytes
- equals total memory cost).
