LocalLUs Parameter Displays Printer LUs as Display LUs

• Microsoft SNA Server for Windows NT, versions 2.0, 2.1, 2.11, and 2.11 Service Pack 1

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=<PrinterLUName1> <PrinterLUName2> ...<PrinterLUNameX>
  

  where <PrinterLUNameX> are LU names separated by spaces.

Windows 95 Clients

• Run the Registry Editor (REGEDIT), and locate the following key:

            HKEY_LOCAL_MACHINE
                SOFTWARE
                    Microsoft
                        SnaBase
                            Parameters
  
  

• 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.
  
  

• Close the Registry Editor.

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:

        HKEY_LOCAL_MACHINE
           SYSTEM
               CurrentControlSet
                  Services
                     SnaBase
                        Parameters
  
  

• 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.
  
  

• Close the Registry Editor.

        Win3x Clients: <winroot>\System\Wdmod.dll
   Windows 95 Clients: <winroot>\System\Snadmod.dll
   Windows NT Clients: <snaroot>\System\Snadmod.dll

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.

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:
