Question : Intranet site gives "you are not authorized" after domain controller fails

We had a complete failure of our main DC over the weekend.  I've transferred all the FSMO roles to another DC, and everyone can log in and get access to files on the server, but our intranet site (which is set to use Integrated Windows Authentication) doesn't seem to be able to authenticate users.

All the servers are running 2003 SP2, and the intranet site is served by IIS 6.  Any ideas?

Check the DNS settings on the intranet server.  They may need to be updated due to the failed server.
