I am posting a set of console extensions that will add right click functionality similar to that in SMS 2003. It is basing on great scripts from myitforum posted by Cory (http://www.myitforum.com/articles/8/view.asp?id=7099). The vbs scripts are taken unmodified from his solution, I only provide XML files and some additional actions based on WMI. I will try to add SCCM specific actions soon (e.g. Software Update detect cycle force etc.). Here is a copy to get you going.

Aside from the above basic actions:

Re-Assign the Site Code
Restart the SMS Agent Host service
Regenerate the SMS Client GUID
Re-Run Advertisements without modifying the advertisement
Discovery
Software Inventory - Delta and Full
Hardware Inventory - Delta and Full
File Collection
Software Metering Usage
Refresh Machine Policies
Evaluate Policies
Update Windows Installer Sources
Change Port Number
Change Cache Size

It also has:

Ping

Get physical memory

Open client log folder

Disclaimer: I have only roughly tested these extensions, prior to production use internal testing and customization is advised. For deploy refer to Readme.txt
