Attachments-wm-multi.vbs

By The Scripting Guys, Microsoft Corporation

This script turns off or on attachment restrictions for Outlook Express by editing the registry, using the WMI System Registry provider. It can run against a local or remote computer.

Attachments-wmi-multi.vbs corresponds to Attachments.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 comma-delimited text file, dcomsec-hosts.csv, which contains the names of computers against which the script will run and the GUID of the application to exempt for each one. This text file must be in the same folder as the script.

Each line of the input file must consist of a computer name, a comma, and either a 1 or a 0, with no spaces before or after the comma: 1 turns restrictions on; 0 turns restrictions off. 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:



client1,1
client2,0
server1,1
server2,0



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 Attachments-wmi-multi.vbs. To run the script, open a command prompt window to the directory of the script and type:

cscript attachments-wmi-multi.vbs

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

'Revision 1.0
'This script can be run against multiple computers to remotely edit
'the registry to turn off or on attachment restrictions for Outlook Express.
'1 turns restrictions on.
'0 turns restrictions off.
'The multiple computers must be specified in a comma-delimited
'text file, attach-hosts.csv, in the same directory as the script.
'Each line of attach-hosts.csv must have a computer name followed
'by a comma, followed by either a 1 or a 0.
'Do not add a newline to the end of the last line.
'Example (turn restriction on for client1 & server1,
'turn restrictions off for client2 and server2):
'client1,1
'client2,0
'server1,1
'server2,0
