Microsoft ISATAP Adapter #3 error

[ggginbd]

When logging onto the computer tonight I got an error Code 31, Microsoft ISATAP Adapter #3 error. When I checked Device Manager, it had Network Adapters opened up with the little yellow caution sign next to ISATAP Adapter #3, and when I clicked on it it gives me the message, "This device is not working properly because it cannot load the drivers required for this device." If I try to load the driver I get the message, "Windows encountered a problem installing the driver software for your device."

Anybody out there have any suggestions?
