Hey Guys I'm using my laptop at my new office and I can't seem to connect with the ethernet. It says there is a conflict with the IP addresses when I plug the LAN cable in. DCHP is set to automatic. I've tried to disable and enable again. Any help you can give would me much appreciated.
A school computer gave this error when it was new and hadn't been set up properly. Admins had a whitelist of mac addresses or s/t that ment computers that werent on the whitelist werent allowed to connect to the internet. maybe your office is the same.
A quick way to test would be to give yourself a static IP. Make sure to ping it first to see if anyone is already using it!
This sounds like someone has set themselves a static IP without talking to the IT dept. Basically the DHCP range is say 192.168.1.10 to 192.168.1.50 and someone has statically assigned themselves one of those IPS - then the DHCP server is still handing it out, as it wasnt setup as a reservation. Releasing the IP will only help if you happen to get a different IP back when you do ipconfig /renew. But it doesnt solve the problem, just temp bypasses it until next time.
Take a note of the IP that DHCP is giving your PC, then take your laptop off the network. Go to a colleagues PC and ping the IP. If it responds then you know someone is using an IP in the allocated DHCP range. If it doesn't respond then its inconclusive as some servers will disable ICMP/ping. You can ask your IT guys to allocate you a static IP if you given them your MAC address. This gets you around the problem (someone else's problem then!)
