Using Active Directory, MS clustered file server, Office 2003

When a group of users access the same file, of course they get a
message stating that
the file is locked by some other user and it usually gives the person's
name that has the
file locked. The exception is that when a particular user has the file
locked, it does not
give that person's name, it simply says 'Nursing'. Since the word
nursing does appear
anywhere in the user's active directory property sheet, I was hoping
somebody could
tell me where excel is getting the data for the user who has the file
locked.

Thanks in advance,

John
