I'm trying to set up a 2 mode peer 2 peer configuration but I'm having a bit of a problem getting it to work.
This is the error I see:
Command attempted:

(Transaction sequence number: 0x0000804400001379009900000002, Command ID: 1)
Error messages:

What I've done (using T-SQL) is create a backup from the "source db" and restore the database to each of the peer nodes.
Then search for the identity columns in the articles I'm going to replicate I reseed them so each node does not have overlapping identities, then create the publication, add the articles, and then the subscribers and finally the distributor agent.
I've been trying to find my mistake for a couple of days now, so hopefully someone here knows what I've missed or have done wrong.
