Re: SMS 2003 Adv Cli- Cache Deletion Problem

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

To to keep the cache size down I'm running a script on a schedule that
deletes elements in the client cache that hasn't been referenced in the last
X number of days. In that way I'm avoiding the cache growing with several
versions for the same package (client patches, scan engines etc.) and also
installations that hasn't been running for that number of days.

To do this I'm using the LastReferenceTime of the UIResource object:
