Laptops retaining IP when cable not connected
I'm having an annoying problem with a whole bunch of the laptops on our network.
They will come to me and tell me that its not connecting to the network,
I'll ipconfig it, and it'll have DHCP IPs assigned to both the WiFi Connection and the Ethernet Connection, even tho the cable is unplugged...
If I ipconfig /release and ipconfig /renew the machine, the Ethernet Connection is then assigned a 0.0.0.0 address and the WiFi Connection picks up a new address and everything works.
I can't remember now if the icon for the ethernet cable shows that the cable is unplugged or not, but I know it's not a hardware issue, because alot of the notebooks are doing it.
Has anybody else experienced anything similar? It's like windows isn't checking the connection and isn't detecting that the connection is lost?
Any help or suggestions would be greatly appreciated! :)
