He's begun to fixate on a system I can't positively identify that connects via SQL on a regular basis. I suspect it's the hosted web server, but I don't have to contact information for the hosting company, and the person with that information is currently in China with a spotty connection and hasn't replied to my emails. I have the name of the host, and the MAC address but not the IP address. Is there any way to find the IP based on the MAC, so I can say for sure "That's the Webhost?" ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
