This is ridiculous kind of, I've set up plenty of computers and a few home networks for friends and family, using multiple os's however for some reason. I cannot connect to internet with Windows XP, is there anything major I have to do? I tried using all the network tools provided but to no avail. Also, it's not my router, because this machine is also on it. The only weird thing I noticed is under my router, it shows this (this computer is Uxxxxxxxxxx, the one with issues is Unknown)

Host Name IP Address MAC Address
Uxxxxxxxxx 192.168.10.101 5C:xx:xx:xx:xx:x
UNKNOWN 192.168.10.102 60:xx:xx:xx:xx:xx

Any help would be greatly appreciated

have u already connected to the internet?

Not on that machine

Check your routers port forwarding rules. In fact, check all of your router settings from Uxxxxxxxxx.
