Unauthorized Internet on Windows 7

[TheXavier]

Hello everyone,

I do IT for a company and a user is having issues periodically with his internet. Seems to happen 2-3 times a week where his internet will stop working and if you hover over this network icon it says "Unauthorized". Logging out and logging back in fixes the issue though. I have seen this issue in the past and I don't think I ever came to a fix for it. I've tried the simple things such as a using a different port, removing the computer and re-adding it to the domain. Have tried looking through system logs for any indicators and I haven't found anything yet. Any help that could be provided would be appreciated.

Do you truly mean just the internet or is the loss of conectivity include the office network? Printers, shares, etc..

You tried a different port meaning a switch from the motherboard ethernet port to a LAN adapter in a PCi slot - or vice versa? Or something else.

Do the router logs provide any insight?

More information needed I think. Thanks.
