Looks like you are starting to get some good arguments: "Either we
fix primary keys to the database, or we go and buy some more hardware,
else we can't run this show".
I will have to admit that the need for third machine was news to me,
but I have never set up log shipping myself.
Actually, add PKeys to those tables does not have to be a killer
work. If there are unique indexes, just drop these and recreate
them as primary keys. If there are not any primary keys, just add
an uniqueidentifier with the default of NEWID() to the tables, and
make that the primary key (nonclustered!). That does not really help
to make the data model any better, but at least you can set up
replication over this dying grace.
