Hey alex,

First, Try to  audit specific logon events on the DC's. you might want to
use an automatic task to collect the logs. That way you can see what the AD
user have been up to.
Second, what firewall do they have ? did they established a log server for
it? If so, try to correlate between the FW log and the AD log.

In a future look, you might want to suggest your client to establish "Honey
Pots" over the network. For example - monitoring an AD user with Domain
Admins permission and a weak password.

Subject: Unknown user found in AD and SonicWall

In a recent audit of one of our clients networks, I came across a new user
in active directory, and a dial in access through the firewall.
It was " Syn IT development access"

The Program, Syn, is a legitimate program used by the client, so we called
the developers and they said the port is used on only special occasions,
none of which the client had ever needed.

What I want to set up is a trap-and-trace for the user, see where they are
connecting from and what they're getting up to.

Any suggestions on how to do this? OS is Windows server 2008R2

Thanks in advance
