SMS: How to Avoid Client Contention Between SMS 1.2 and SMS 2.0

When a Systems Management Server 2.0 client is authenticated in a Systems Management Server 1.2 site, the 1.2 site may attempt to replace the 2.0 client software with 1.2 client software. To prevent this from occurring, replace the Smsls.bat file at the 1.2 site with a version of Smsls.bat that recognizes a 2.0 client. This version of the Smsls.bat file will exit without installing the Systems Management Server 1.2 client software.

You can get the new version of the Smsls.bat logon script by applying Systems Management Server 1.2 Service Pack 4 to your 1.2 site. The service pack Setup program will replace the Smsls.bat file. Alternatively, you can manually copy the Smsls12a.bat, Check20.exe, and Checkver.exe files from the Systems Management Server 2.0 CD to the Winnt\System32\Repl\Export\Scripts directory of your Systems Management Server 1.2 site server, and then rename Smsls12a.bat to Smsls.bat.

If you are using a customized Smsls.bat file at your 1.2 site, you can manually copy the Check20.exe and Checkver.exe files from the 2.0 CD to the Winnt\System32\Repl\Export\Scripts directory of your 1.2 site server. After doing so, perform the following steps:

1. In the customized 1.2 Smsls.bat file, find the following line:
   
   

         if "%OS%" == "Windows_NT" goto RUN_NT:RUN_DOS
   						

   
   
2. Immediately after this line, insert the following lines:
   

      REM call checkver to verify this is a supported OS for 2.0
      %0\..\checkver
   
      if errorlevel 1 goto RUN_DOS_2
   
      REM call to check20 to check if this is a 2.0 client
      %0\..\check20
   
      if errorlevel 1 goto RUN_DOS_2
   
      REM This is an SMS 2.0 Client skip processing
      goto RESTORE
   
      :RUN_DOS_2
   
      REM This is not an SMS 2.0 client process script
   						

   
   
3. Find the following line of code:
   

         :RUN_NT
   						

4. Immediately after this line, insert the following lines:
   

      %0\..\check20 /v
      if errorlevel 1 goto RUN_NT_2
      goto RESTORE
   
      :RUN_NT_2
   						

To prevent Systems Management Server 1.2 clients from being upgraded by the Systems Management Server 2.0 sites they get authenticated by, perform the following steps:

1. Create a file in the C:\ directory of the client computer. This file should contain the following lines:
   

   REM The presence of this file prevents SMS 1.2 client software
   REM from being overwritten with SMS 2.0 software, provided that
   REM the login script at the SMS 2.0 site has been modified to look
   REM for this file and exit if it is found and
   REM provided that the client setup methods other than Windows NT Logon
   REM have not been enabled at that site.
   						

   
   
   
2. Distribute the file created in Step 1 of this procedure to the 1.2 clients that are likely to visit 2.0 sites.
3. At each of these sites, go to the Winnt\System32\Repl\Import\Scripts directory of the logon server and edit the Smsls.bat file so that it detects the file you created and exits if that file is found. For example, you could add a line like the following:
   

         if exist c:\newfile.txt goto end
   						

4. If you expect the visiting computer to be running Windows NT, make sure the Windows NT Remote Client Installation method is disabled.
