Here at my firehouse we have a wireless netowrk for the laptops in our engines. All connect to the designated network just fine (except one) and it has the same settings as the other laptops using Windows XP

What is happening is this.... I keep getting a pop up bubble stating...
"Windows was unable to find a certificate to log you on to the network”
The affected computer has internet access and is able to access other computers ont he network but other computers cannot access into that computer.

The laptop's network settings are using WPA2-PSK with an AES Encryption
and like I said it has the same exact settings as the other computers not receiving this error message
