Got hacked and now cannot Generate SSPI context



(DC=AdvServer200; SQL 2000; wkstation XP pro (logged into domain with Admin
rights) -- all with latest SPs applied).
We just got hacked via ftp and have strengthened our Administrator pwd. Now
I cannot use EM or connect to a db with existing programs (I can connect
using SQL Server Authentication) I know this has to be a
password/authentication problem. Just don't know what/where I need to
change the passwords in SQL. Any specific help welcome.
