How to use a visual basic script to install the 824146 (MS03-039) or 823980 (MS03-026) security patch on remote host computers


View products that this article applies to.

Summary

This article includes a sample Microsoft Visual Basic Scripting Edition script that is named Patchinstall.vbs. This script is an example of how a network administrator can use Windows Management Instrumentation (WMI) scripting to install the 824146 (MS03-039) or the 823980 (MS03-026) security patch on remote host computers that do not have the patch installed in a Microsoft Windows NT, Windows 2000, or Windows Server 2003 domain environment. The Patchinstall.vbs script takes a file (Ipfile.txt) that contains IP addresses as input and installs the 824146 (MS03-039) or the 823980 (MS03-026) security patch from a known location on the remote host computer (C:\Patchinst.exe). For additional information about the 824146 (MS03-039) security patch, click the following article number to view the article in the Microsoft Knowledge Base:
824146� MS03-039: Buffer overrun in RPCSS may allow code execution
For additional information about the 823980 security patch, click the following article number to view the article in the Microsoft Knowledge Base:
823980� MS03-026: Buffer overrun in RPC may allow code execution
For additional information about a tool that network administrators can use to scan their network for computers that do not have these security patches installed, click the following article number to view the article in the Microsoft Knowledge Base:
827363� How to use the KB 824146 scanning tool to identify host computers that do not have the 823980 (MS03-026) or 824146 (MS03-039) security patches installed

Notes

  • You must have administrative permissions on the remote destination computers to successfully install the 824146 or the 823980 security patch.
  • Microsoft Windows XP-based destination computers must be joined to a Windows NT, Windows 2000, or Windows Server 2003 domain to successfully use the Patchinstall.vbs script.
  • The Patchinstall.vbs script uses Windows Management Instrumentation (WMI). WMI depends on the Distributed Component Object Model (DCOM). Therefore, the Patchinstall.vbs does not work on destination computers where DCOM has been disabled to work around the vulnerability that is addressed by Microsoft Security Bulletins MS03-039 or MS03-026.
  • The 824146 or the 823980 security patch packages must be located in a local folder on the computer where you run the Patchinstall.vbs script, and the packages must be renamed to Patch_XP.exe (for Windows XP), Patch_W2K.exe (for Windows 2000), and Patch_W2K3.exe (for Windows Server 2003).
  • You can modify the Patchinstall.vbs script to install other patches.

More information

The Patchinstall.vbs script performs these tasks:
  • The script reads a list of IP addresses for the remote host computers where you want to install the 824146 or the 823980 security patch. The script obtains this list from an ASCII text file (Ipfile.txt) that contains a list of IP address (one IP address per line). For example, you can use the Vulnerable.txt log file from the KB824146 scanning tool for the Ipfile.txt file.
  • The script obtains the first IP address from the list.
  • The script determines the Windows version on the destination computer.
  • The script maps drive Z on the script computer to C$ on the destination computer.
  • The script copies the correct version of the patch (for Windows XP, Windows 2000, or Windows Server 2003) to C:\Patchinst.exe on the destination computer (by using the drive Z mapping).
  • The script causes the patch to be installed, and then automatically restarts the destination computers without any user input or dialog boxes by using the -q -f switches (Unattended installation mode).
  • The script waits for the installation to complete.
  • The script tries to delete the C:\Patchinst.exe file on the destination computer.
  • The script removes the drive Z mapping.
  • The script processes the next IP address in the list.
Important Microsoft recommends that you modify this sample script for your network environment, and that you then test your script in a test environment before you use it in a production environment.

To use the Patchinstall.vbs script, paste the following script in a text file that is named Patchinstall.vbs. Then, run the Patchinstall.vbs script by using the following command line:
cscript patchinstall.vbs Ipfile.txt LocalPathToPatches
In this command, Ipfile.txt is a text file that contains a list of IP addresses for the remote host computers where you want to install the 824146 or the 823980 security patch. LocalPathToPatches is the full path of a folder that contains the 824146 or the 823980 security patch packages (renamed to Patch_XP.exe for Windows XP, Patch_W2k.exe for Windows 2000, and Patch_W2k3.exe for Windows Server 2003).
