Unknown user found in AD and SonicWall

[Alex Dolan <dolan.alex () gmail com>]

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
