SQL 2000 Enterprise Manager Restore DB Bug

I recently built a triple redundant DB where there are two warm standbys not
e
this is SQL 2000 Standard.  On each standby i have a program that reads a
directory looking for new TLOG backup files that get pushed to it by robocop
y
from the active  node.  There are to user db's that are subject to this.  It
just so happens that my log restore program kicked off and restored both
databases at the same time.  As such the msdb's restorehistory table contain
s
two records with identical restore_date values.  When this happened I can no
longer restore to either standby user db or and any attept to restore either
DB from enterprise manager(all taskes>Restore Database) yields the following
error:
Error 512: Subquery returned more than 1 value. This is not permitted when
the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an
expression.

I ran a trace on the DB and found the following are executed when Enterprise
Manager tries to populate the restore Dialog Box:
declare @b int;
set @b =  (select backup_set_id from msdb..restorehistory o where
o.restore_date = (select max(i.restore_date) from msdb..restorehistory i
where i. destination_database
_name = N'DB1'));
select min(backup_set_id) from msdb..backupset where type = 'L' and
backup_set_id > @b and database_name = (select database_name from
msdb..backupset where backup_set_id = @b)

The second line, set @b = (select.... blah....) is doing a select over the
entire table but does NOT have an AND clause qualifying the results for ONLY
the particular database being restored.  The query should be: (The differenc
e
is in CAPs)
set @b =  (select backup_set_id from msdb..restorehistory o where
O. DESTINATION_DATABASE
_NAME=n'DB1' and o.restore_date = (select
max(i.restore_date) from msdb..restorehistory i where
i. destination_database
_name = N'DB1'));

Updating the restore_date column on one of the 'conflicting' rows will
correct the problem.
