IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, click the following article number to view the article in the Microsoft Knowledge Base:

256986 Description of the Microsoft Windows Registry



SYMPTOMS
If 3270 Printer LUs are assigned to a computer using the LocalLUs parameter, the printer LU names are improperly displayed as 3270 Display LUs when viewed in a 3270 Emulator.



CAUSE
The LocalLUs parameter was not designed to support printer LUs.



RESOLUTION
A new parameter called LocalPrinterLUs has been added to provide the capability of assigning printer LUs to a computer. If this parameter is present on a SNA Server client, the printer LUs in the User/Group record are replaced with the printer LUs specified in the LocalPrinterLUs parameter. The LocalPrinterLUs parameter supports a maximum of 10 printer LUs.

The LocalPrinterLUs parameter is specified as follows:

Win3x Clients
 Add the following entry to the [WNAP] Section of the WIN.INI file:

LocalPrinterLUs=  ...

where  are LU names separated by spaces.

Windows 95 Clients
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

  Run the Registry Editor (REGEDIT), and locate the following key:          HKEY_LOCAL_MACHINE SOFTWARE Microsoft SnaBase Parameters </li> Add the following string value to the Registry key:

String Value Name: LocalPrinterLUs

Data: <PrinterLUName1> <PrinterLUName2> ... <PrinterLUNameX>

where <PrinterLUNameX> are LU names separated by spaces.</li> Close the Registry Editor.</li></ul>

Windows NT Clients
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.   Run the Registry Editor (REGEDT32), and locate the following key: <pre class="fixed_text">     HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Services SnaBase Parameters </li> Add the following value to the Registry key:

Value Name: LocalPrinterLUs Data Type:  REG_SZ Data:      <PrinterLUName1> <PrinterLUName2> ...<PrinterLUNameX>

where <PrinterLUNameX> are LU names separated by spaces.</li> Close the Registry Editor.</li></ul>

The following files have been updated to add the support for the new LocalPrinterLUs parameter:

Win3x Clients: \System\Wdmod.dll

Windows 95 Clients: \System\Snadmod.dll

Windows NT Clients: \System\Snadmod.dll

<div class="status_section">

STATUS
Microsoft has confirmed this to be a problem in SNA Server versions 2.0, 2.1, 2.11, and 2.11.sp1. This problem was corrected in the latest Microsoft SNA Server 2.11 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

<div class="moreinformation_section">

MORE INFORMATION
The LocalLUs parameter is used to specify the LUs to be used on the system, regardless of which user is logged on. If this variable is not used, SNA Server assigns LUs based on the User/Group records defined in SNA Server Admin. Reference to Appendix C of the SNA Server "Reference Guide" for more details on the LocalLUs parameter.

For additional information on how SNA Server currently handles assigning LUs to a computer, please see the following article in the Microsoft Knowledge Base:
