SYMPTOMS

SNA Server Admin hangs on startup and the SnaBase service encounters the following error if Windows NT is installed with the Novell NetWare Requestor for Windows NT, version 1.01:

Event 567:
Creation of named pipe failed, rc = 10048

Event 624:
Creating dump file c:\sna\traces\SNADUMP.LOG for SNABASE.EXE

CAUSE

The SnaBase service attempts to open the same socket number on both IPX and SPX, although the Novell IPX/SPX driver for Windows NT does not allow this, returning socket error 10048 which means the address is already in use. Event 624 is logged to indicate that an unrecoverable error detected by SnaBase.

RESOLUTION

An update to SNA Server 2.11 corrects this problem by supporting the ability to configure the SPX port number used by the SnaBase service.

Microsoft has updated the following files to correct this problem:

   On the server and Windows NT clients:  <snaroot>\SYSTEM\SNANW.DLL
   Windows 95 clients:                    <win95root>\SYSTEM\SNACNW.DLL
   Windows 3.x clients:                   <winroot>\SYSTEM\NWCLI.DLL
                

To configure the SPX port number, install the new file and add the following registry value on the server under the HKEY_LOCAL_MACHINE subtree under the following subkey:

   /SYSTEM/CurrentControlSet/Services/SnaBase/  Parameters/SnaSpx

Value Name: SnaBasePort
Data Type:  REG_DWORD
Data:       <hexadecimal number>
                

<hexadecimal number> is the port number in hexadecimal. This number must not match the default of 0x84C8.

When this parameter is specified the SnaBase uses the new port number for client "sponsor" connections over SPX. The default port number (0x84C8, or 33992 in decimal) is still used for server to server (IPX) communication. This fix requires an update to all clients (except MS-DOS based clients) because the clients assume that the SnaBase SPX port is always 0x84C8. However, there is no client-side entry required because the server port number is found dynamically through the Netware bindery.

STATUS

Microsoft has confirmed this to be a problem in SNA Server for Windows NT. This problem was corrected in the latest SNA Server for Windows NT, 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):
