Mac Address is not allowing PC on the network
Posted on 2004-04-29
Where I work, for some weird reason clients have been putting tickets in that there PC's are not able to log onto the network. After troubleshooting the PC and running all sort of IPconfigs/etc the machine still will not get onto the network. I could only log on locally to the machine. Normally when a PC is infected with a Virus we suspend there MAC address and they are not able to login. But this does not seem to be the case here, I have ran Virus scan on his machine and he is clean. I finally found a workaround, but i don't know if it's doing harm to the NIC or the Network. I came up to the conclusion that the Network might not know recognizing the MAC address, I used this program called SMAC and it changed the IP address to some default value of (01-01-01-01-01-01-01- etc)
This then allowed the machine to get on the network. I'm happy that this worked but I need to know why this worked and is it going to hurt the network in any fashion and is there another way to trobuleshoot this problem.
***The machine was a desktop not a laptop and it had not been moved from the location***
Any Help ?
