Error 3846: The Control Point Name is Invalid

ID: Q137577

The information in this article applies to:
  • Microsoft SNA Server, version 2.11
    on the following platforms: NT

SYMPTOMS

After you install Microsoft SNA Server version 2.11 on a Microsoft Windows NT server, the following error message appears when you run SNA Admin:

Error 3846:
The Control Point Name is invalid.
The name can be from one through eight alphanumeric characters long.
This problem occurs when the Windows NT server name begins with a digit.


CAUSE

There is an IBM SNA standard that an APPC control point name cannot begin with a digit. If the Local Control Point Name is not already configured on the SNA Server, the Microsoft SNA Server 2.11 Admin program automatically sets the Local Control Point Name (in the server properties dialog) to the Windows NT computername. If the Windows NT computername starts with a digit, the SNA Admin program sets the local control point name to an invalid value.


WORKAROUND

To work around this problem, open the COM.CFG file with the command line command:

SNAADMIN C:\SNA\SYSTEM\CONFIG\COM.CFG
This opens the SNA Server configuration file off-line and allows you to make changes the configuration.

If the "Servers and Connections" window in SNA Server Admin lists the SNA Server Name, double-click on the SNA Server Name and enter a valid Control Point Name.

If the Servers and Connections window has only "No Assigned Services" listed, use the following process to add a SNA Server with a valid Control Point Name:
  1. Select Services from the SNA Server Admin Menu Bar.


  2. Select New Server from the Services drop down menu.


  3. Enter the NT Computer Name in the Server Name field on the Server Properties dialog.


  4. Enter a valid Control Point Name in the Control Point Name field. If you enter a Control Point, you must also enter a Network Name.
