Running SQL 2k / Win 2k

I am getting an error on Replication Monitor->Agents->Misc
Agents->Expired Subscription Clean up that reads 'Executed as user:
ROUSES.COM\Administrator. Invalid object name 'sysarticles'. [SQLSTATE
42S02] (Error 208) Invalid object name 'sysarticleupdates'. [SQLSTATE
42S02] (Error 208) Associated statement is not prepared [SQLSTATE
HY007] (Error 0). The step failed.'

What dB is this table or tables missing from?? How do I recreate
them??

AHIA,
Larry...
