I have a box running SQL Server 7 (I know) on Windows XP (I know).
All of the sudden, I'm unable to use Windows authentication to connect to the database from the local machine.
I can connect using SQL authentication on the local machine.
I can connect using both SQL and Windows authentication from another machine.
Here's the error I get when using Query Analyzer to connect to the local database using Windows authentication.

I've tried connecting using both the machine name, . and localhost.

Any ideas?
Thanks!
Update: Added Screenshot of server protocols
