Maybe you have an open wireless network?.<br />
If your running RAS or RADIUS, maybe some has managed to dial in.<br />
<br />
You need to look at your network setup and identify the weak points<br />

My wireless network is configured to only allow specific NICs and my remote access could only be VPN, no dial in, and that is secured by Authentication.<br />
<br />
If someone tries to get into the system without authenticating will they still be assigned a lease by DHCP?<br />
<br />
Thanks,<br />

I believe it was my wireless router. &nbsp;Since I disconnected it, those leases have not reappeared.<br />

I have DHCP running on my SBS2003 server for my internal workstations. &nbsp;When I look at the address leases under the scope I see two unknown leases, one belonging to a Jocelyn and another that says kteaguexp.noam.tycovalves.<wbr />com. &nbsp;We only have 5 workstations and none of them are identified by these two names. &nbsp;<br />
<br />
Where are these two leases coming from and should I be worried???<br />

Unknown leases on my DHCP server

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
