Offline Servicing Failed - Unable to delete existing mount directory

Hi All,

I'm unable to run offline servicing on my install image, as the deletion of a previous mount point fails (from OfflineServicingMgr.log):

Deleting file \\?\C:\ConfigMgr_OfflineImageServicing\GRO000E7\ImageMountDir\Windows\Fonts\trebucbi.ttf, FAILED, Win32 Error = 1168

Failed to remove previously existing staging folder C:\ConfigMgr_OfflineImageServicing\GRO000E7, GLE = 1168

Failed to remove the staging folder C:\ConfigMgr_OfflineImageServicing, GLE = 1168

I've tried:

• DISM /cleanup-wim - returns all stale files removed, but the directory remains
• DISM /cleanup-mountpoints - returns all stale files removed, but the directory remains
• Manually deleting the folder - which returns the error 0x80070490 Element not found

I presume I could work around this by deleting the existing image in SCCM, re-creating using the WIM, then it should have a different packageID and hence use a different mount point for offline servicing?

I'd rather not do this, so if anyone has any ideas on something else to try, would be greatly appreciated.

Thanks,

Iain
