Our desktop guys copy user data to a server before they wipe machines. Once the data is copied back over, they delete the data. One of the techs escalated an issue to me (SysAdmin) where he could not delete some of the data from the server. I took ownership, still could not delete but I noticed the attributes read "AC", so it's an archived, compressed file? I try to uncompress, or remove the compress attribute through cmd, and I get the attached error.
How can I get these files off the server without reboot / wiping the drive?
Windows Server 2003, SP2
