I would not show up in AD because it does not have a Domain account. &nbsp;I would try the following:<br />
nslookup &quot;ip address&quot;<br />
<br />
This should give you the DNS name for the box. &nbsp;Also, search for the IP address in DHCP and/or WINS to get the name for the box.<br />
<br />
Just some suggestions, I'm not a security expert either.<br />

Erick,

I would not show up in AD because it does not have a Domain account.  I would try the following:
nslookup "ip address"

This should give you the DNS name for the box.  Also, search for the IP address in DHCP and/or WINS to get the name for the box.

Just some suggestions, I'm not a security expert either.

Thanks,

This might sound like a simple question but I am kind of new to the security side of networking. &nbsp;How am I able to find a rouge system on my network? &nbsp;I ran GFI's Langaurd and it came back with the IP address it is using and also says it is probably a Unix box. &nbsp;It is running Samba 2.2.3a(build26). &nbsp;But when I look for it in active directory users and computers it does not show up. &nbsp;The Unix box has three open ports 139,110,25. &nbsp;I can ping it but can't trace it down. &nbsp;Any suggestions are exteremly invited.<br />

Rouge System

Operating system security (OS security) is the process of ensuring OS integrity, confidentiality and availability. OS security refers to specified steps or measures used to protect the OS from threats, viruses, worms, malware or remote hacker intrusions. OS security encompasses all preventive-control techniques, which safeguard any computer assets capable of being stolen, edited or deleted if OS security is compromised, including authentication, passwords and threats to systems and programs.
