Scenario1.vbs

By The Scripting Guys, Microsoft Corporation

This script initiates an automated installation and configuration process for Windows XP Service Pack 2 on multiple network hosts. Scenario1.vbs gets a list of remote machines from a text file, copies two scripts, install.vbs and runonce.vbs, to each machine, and then launches the first script on each machine.

The script runs on the administrative workstation, and all scripts must be located in the same folder. The credentials under which the scripts run must have administrative privileges on each host.

In the basic scenario, the SP2 setup file is on a remote server accessible to all network hosts on the list. To run a variation of the scenario in which the SP2 setup is copied to local hosts and run from there, rename install.vbs to another name (such as install-remote.vbs) and then rename install-local.vbs to install.vbs. You must also make minor changes in scenario1.vbs and install.vbs documented in those scripts.

The other scripts perform the following functions:

Install.vbs

  • Runs SP2 setup from a remote server.

  • Sets AutoAdmin and RunOnce registry entries on host.

  • Logs results to a text file, computername-sp2-instlog.txt, and copies the file back to administrative workstation.

  • Forces a reboot, after which runonce.vbs is automatically launched.

Runonce.vbs

  • Runs after machine reboots for first time, launched by RunOnce reg entry.

  • Configures Windows Firewall to allow certain programs and open certain ports. You must edit these settings to reflect the configuration of your network.

  • Enables remote administration on Windows Firewall so that remote scripts and administrative tools can again run against this host.

  • Resets AutoAdmin and RunOnce registry entries.

  • Logs results to text file, computername-sp2-clnuplog.txt and copies the file back to admin workstation.

  • Again forces a reboot.

Further explanation of Scenario 1 and the role of each script is contained in the introduction to these scripts at http://www.microsoft.com/technet/scriptcenter/solutions/appcompat/default.mspx

Scenario1.vbs corresponds and adds functionality to StartRemoteIns.vbs, one of the scripts that ships with Application Compatibility Testing and Mitigation Guide for Windows XP Service Pack 2 and which are documented in the Appendix. You can download a Windows Installer (.msi) file that installs the Guide and its associated scripts from:

http://www.microsoft.com/downloads/details.aspx?FamilyId=9300BECF-2DEE-4772-ADD9-AD0EAF89C4A7&displaylang=en

Input for this script comes from a text file, computers.txt, which contains the names of computers against which the script will run.

Each line of the input file must consist of the name of a computer. Each computer must be accessible on the network and the credentials under which the script is run must have administrative privileges on it. For example:



client1
client2
client3
client4



Be sure there is no line break after the final line, as this will be interpreted by the script as an empty string.

To use the script, copy the code, paste it into Notepad, and then save the script as scenario1.vbs. Then create a text file with the name of a computer on each line, as described above, and save it as computers.txt in the same directory as the script. To run the script, open a command prompt window to the directory of the script and type:

cscript scenario1.vbs

If the default script host on the computer is Cscript.exe, the initial "cscript" may be omitted.
