Hello,<br />
<br />
I used the DHCP utility on my firewall to determine that a .35 and .105 are downloading a lot, maybe a virus or maybe yahoo launch or something. &nbsp;I would like to find those computers in our network, but unfortunately when I do a DNS lookup on our DNS server those addresses are not listed. &nbsp;.100 and higher is for DHCP, while under .99 is static (so that should be easier to find, right?). &nbsp;Is there a way to block specific IP addresses from doing anything, or way to locate them or what they are doing? (tools, etc).<br />
<br />
Thanks,<br />

How can I stop/locate specific internal IP addresses?

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.
