I am trying to set up replication. When setting up the publisher there are several hundred tables that I cannot select because it states there are no primary keys. However when I go into SQL Management Studio and try to create a primary key on one of those tables it will not create it because the primary key already exists. When I view the keys for any of these tables or in design view there is no primary key shown yet it exists. We have a copy of this database in another environment and when I view the same table the primary keys are visible. I thought it might be my SQL Management Studio so I tried it from several other workstations and still the same result. I guess since it does not appear in SSMS the replication wizard thinks it does not exist as well. Any idea what the issue might be? Please advise.
