Permissions Required For Sp_databases

This may be the wrong forum for this - if so, please direct me to the appropriate forum.

I've
recently upgraded to MSSQL 2005 and I'm trying to execute the
sp_databases stored procedure, but I'm having what looks like
permissions problems. I can execute the stored procedure, but it
doesn't return any results. As far as I can tell, the problem is that
my userid can't see any rows in sys.master_files (I can select from the view, it just doesn't return any rows).

I've tried any
number of things to get this to work, but the only thing that's been
successful is to change my userid's database role membership to
db_owner. In the long run, this isn't really a viable solution for me,
since my userid should only really have read(select) access to the
database in question.

I'd appreciate any pointers that you can
give me - I figure I'm doing something stupid, but haven't been able to
figure out what, yet.

Thanks,
Jeff
