The xp_slsreadprogress stored procedure returns 0 (zero) for any of the SQL 2000 databases whenchecking the progress of backups & restores. Backups and restores are working normally on both instances.
Software Defect - sp xp_lslReadProgress procedure does not work on Win - x64 with SQL 2005 - x64/SQL 2000 - x32 on the same machine.
Fixed in a future version of LiteSpeed.
