Hello Experts!  
I need some help.  I have a problem that I can't find an answer to and I am out of answers.

I have a laptop in our company domain that is having issues with his LAN connection in our corporate office ONLY.  He is not able to get to the internet when connected in the office but the LAN connection works fine on every other outside network we have tried it on. I have taken the laptop home and tested it and it works fine.  Also we have tested it in hotels and there is not LAN issues.  BUT the odd thing is that the wireless connection works PERFECTLY all the time, even in the corporate office.  This computer NEVER had a issue until randomly it stopped working, it just doesnt make sense.  This is the only computer that is having an issue in our office.  Below is what I have tried to make it work.

- Pinging Google.com via IP address
- Different ethernet cable(s) and ports
- Uninstalled/reinstalled new drivers
- Turned off firewall
- ipconfig/release, renew, flushdns, registerdns
- Set a static ip/subnet mask/dns/gateway
- Virus scan (malwarebytes)
- Checked for IE proxy
- Reinstall Windows 7

There maybe a couple other things i tried but just cant remember at this time.  Any help would be great!
