System Center Configuration Manager (SCCM) client has a cache on the server. If needed this can be cleaned by following these steps:
1. Open Control Panel-> Configuration Manager. Press the Cache tab.
3. Change the location of future cached files, if needed, by clicking the ‘Change Location’ button and choosing a new location on your hard drive.
The default location is %windir%\system32\CCM\Cache.
4. Delete all cached files in cache by clicking the Delete Files button. Press Yes if asked to confirm, and wait for your temporary program download folder to empty.
5. Click OK to save your changes, and exit the window.
