Initialize Pull Transaction From Backup

I'm trying to initialize a subscriber from a backup for a pull subscription. The publisher was started before the full backup was made. I followed the instructions @ Books Online topic "Initializing a Transactional Subscription Without a Snapshot" http://msdn2.microsoft.com/en-us/library/ms151705.aspx and How to: Initialize a Transactional Subscriber from a Backup (Replication Transact-SQL Programming) http://msdn2.microsoft.com/it-it/library/ms147834.aspx . I initialized the subscriber by restoring the db before I run the create subscriber scripts. All agents run successfully except for the following:

The network setup is that the publisher and the subscriber are in 2 different domains with the distribution database at the publisher. The subscriber agent is able to connect and run however the error on the subscriber side is:

"Agent message code 14080. The remote server "subscriber" does not exist, or has not been designated as a valid Publisher, or you may not have permission to see available Publishers."

The warning on the publisher side is in the Replication Monitor where in the status it says Uninitialized Subscription.

Any ideas on why it says it isn't initialized? Is there a StoredProc that I have to execute to initialize from backup?
