Unable to Unload TCP/IP Utilities (113867)


The information in this article applies to:

  • Microsoft LAN Manager 2.2
  • Microsoft LAN Manager 2.2b
This article was previously published under Q113867

SYMPTOMS

TCP/IP utilities such as Sockets, DNR, Telnet or BAPI cannot be unloaded after they are loaded on a LAN Manager 2.2b client running TCP/IP stack 1.0a. If you try to unload one of these utilities, an error message states that the utility is not loaded.

Changing load order causes symptoms to differ but does not correct this problem. In the most drastic case, loading Sockets last causes the machine to hang when you try to unload it.

The TCPTSR.EXE and TCPDRV.DOS are dated October 1993. SOCKETS.EXE and DNR.EXE are dated June 1993. Telnet and BAPI are dated February 1992.

CAUSE

Sockets returns an invalid buffer size, which creates the problem.

STATUS

Microsoft has confirmed this to be a problem in LAN Manager versions 2.2 and 2.2b. A fix has been included in CSD0.099. Contact Microsoft Product Support Services for more information.
