Hello,
When the company I work for was purchased two years ago, I was required to
give the administrative password to the new owner's son. In the past week, I
have received many comments from users who suspect he is logging in remotely
and monitoring users' email by going into their accounts and reading their
messages. The first thing I would like to do is see if he is actually doing
it. Is there some sort of alert that I can set up to tell me, or log when he
logs in? I can look at the security log in event viewer, but there are so
many events that have the Administrator name, I don't even know what they
all mean. Also, currently the log only holds about a two days of events. I
could increase the size, but it would start taking much more space on my
hard drive. Less than one day of data is 65MB. Finally, I don't think the
event logs are where I go to see if he is logging into other users'
mailboxes. That said, are there any kind of events that I could look for in
Exchange that might tell me what I need to know?
Secondly, if I find that he is poking around in the mailboxes, I have to cut
off his access to the domain, or at least to the inside of other users'
boxes. There were only two ways I could figure to do this:
1. Change the administrative password - From what I understand, this is not
as easy as it sounds because of other services/programs running under that
administrative account as well as the local admin account on the individual
PCs. I have looked around for some sort of guide, but I can't find anything.
Any ideas?
2. Lock out administrative access to Exchange - I figured that I could deny
read permissions on the store to the Administrator account. Since some
account needs to be able to have read permissions, I could create another
account, and establish read permissions on it. I would also have to somehow
prevent the Administrator account from being allowed to re-grant itself
permissions. This solution sounds pretty complicated to me (not to mention
that I have no idea how to do it), but maybe it's easier than changing the
password on the account.
If anyone has any ideas, I would definitely appreciate the help.
Chris
