LAN says connected, but can't hit internet
Posted on 2012-04-09
One of our employees had an issue with his computer last week. He had it sent to me to be reimaged as it was slow due to prolonged use, etc. I reimaged it, put our new antivirus (Sophos) on it and sent it back. Everything was the same except the AV which numerous others in our company have as well, so I don't think that's the issue.
When the user received the computer, he plugs in with ethernet cord and it connects to the network, says it's connected, but cannot hit the outside world. It can hit a local snap server which means the connection is working. He just can't go to any www. site.
I thought it may just be biting the dust so I overnighted him a newer model computer, same load as always. He got it and is now telling me it's doing the same thing. I had him try his computer in another office with another ethernet cord and it did not work. He had another employee bring their computer into his office and theirs worked fine. Made me sound like somehow, two bad computers...
I then had him take his computer home to test on his home network. He took the ethernet cord from his office and plugged in to his wireless router (I ensured he had the wireless disabled), and the LAN connection worked. He was able to access the internet on his home network.
I had him go into their networking closet and switch his ethernet cord that makes his jack live to a different port in the switch and it still didn't work.
So the end results is:
- User can't connect to internet at office
- Other employee CAN connect to internet at User's desk
- User CAN connect to internet on home network
Any ideas what could be causing this?
