Problem Pushing Subscriber Updates To Publisher In Transactional Replication

I have a primary and secondary servers both running Windows 2000 SP3 with SQL 2000 SP3. I have set up transactional replication with the primary server as publisher and the secondary server has the distributor and subscriber DB. I am testing the scenerio where my primary server goes down and I have to make updates to the secondary server until my primary server comes back up. I am able to update my subscriber database and the transactions go into the MSreplication_queue table to be pushed back to the primary when it comes back up. When I bring the primary server back up and start the queue agent job it starts pushing the transactions over and then stops after 4 or 5 transactions with the error "Failed while applying queued message to publisher". I have attached part of the log file for the agent below

In the sql server logs I am getting this message:

Any help would be greatly appreciated
