SMS: IE 3.01 Security Patch Causes SMSRUN16 to Stop Responding (167759)

SYMPTOMS

Installation of the Microsoft Internet Explorer 3.01 Security Patch requires a restart to finish processing. During the initial log on to some Windows 95 Systems Management Server clients following this restart, Smsrun16.exe may either cause a general protection fault (GPF) or stop responding. Later logons are unaffected. A typical GPF looks like the following :

SMSRUN16 caused a general protection fault in module SMSRUN16.EXE at 0001:00001e07.

If Smsrun16.exe stops responding, Package Command Manager (PCM) and Program Group Control (PGC) may not be initialized correctly; however, examination of the client's Smsrun.log file located in the Ms\Sms\Logs directory outlines how far the execution of Smsrun16.exe progressed before it stopped responding.

   [04/16/97 11:44:08] C:\MS\SMS\BIN\SMSRUN16.EXE ==>
   Starting execution, command line =  <empty>

   [04/16/97 11:44:08] C:\MS\SMS\BIN\SMSRUN16.EXE ==> Windows 95 network
   driver detected.

   [04/16/97 11:44:08] C:\MS\SMS\BIN\SMSRUN16.EXE ==> Logon root directory
   set to \\COLINHUNT\SMS_SHR

An unhindered logon's Smsrun.log looks similar to the following, successful completion being indicated by the final "End of main message loop" entry :

   Starting execution, command line =  <empty>

   [04/15/97 14:32:31] C:\MS\SMS\BIN\SMSRUN16.EXE ==> End of main message
   loop.

CAUSE

The post-restart installation mechanism of the Security Patch causes Smsrun16.exe to be locked out.

WORKAROUND

To work around this problem, do either of the following:

Restart the affected client and log on again.
-or-
Install Internet Explorer 3.02, rather than the 3.01 Security Patch. Internet Explorer 3.02 implements all the security fixes provided with version 3.01, but does not exhibit this problem.

STATUS

Microsoft has confirmed this to be a problem with Systems Management Server version 1.2. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
