This is a weird urgent issue. It appears that a mystery device name is attaching itself to a set of computers at a site of mine. The site kept complaining about slowness, so I went into my network monitoring system and saw a named device - mssd10109.ccps.local listed as the culprit. The only problem, this is not a device listed on our Lan and this is also not our domain. I mistakenly assumed that it was someone's personal device being used on our network. When that didn't pan out, I used an application called Advanced IP scanner, saw the device and got the IP. The software allowed me to see the users profile on the computer and was able to find the culprit computer, the only problem was the IP's were the same, but the device name was correct on the computer. The mysterious name was no where to be found on the laptop. I had the user shut the computer down and I took it off my domain in case that is a virus. I re-ran the IP scanner and now that device name shows up under another IP address at that site. Has anyone ever heard of anything like this? This is serious because it is maxing out our bandwidth at that site.
