After receiving an email from our Exchange Server 2003 that said, "The
following disk is low on free disk space. Low levels of free disk space can
cause performance problems and prevent users from saving files on the disk."
I checked to see what might be the problem. I noticed that a file with the
extension .gthr was over 23Gb's. I then checked this file extension online
and found a reply to on a forum saying that there was someone spying on my
server.
Is this true and if so, what do I do to get rid of it and prevent it in the
future?
Please help, I'm a novice.
