Snapshot failing with following error message - Error 14151 Severity 18, State 1

I'm trying to create three publications on one server, all going to the same subscriber.

Once I was able to create successfully and but am having issues with the last two, where I can't get the snapshot to run-

Here are the errors -

Replication-Replication Snapshot Subsystem: agent servername-test_DB-test_DB-92 failed. The replication agent encountered a failure. See the previous job step history message or Replication Monitor for more information.  The step failed.

Error: 14151, Severity: 18, State: 1.

Agent shutdown. For more information, see the SQL Server Agent job history for job servername-test_DB-test_DB-92'.

Any help would be greatly appreciated.

Thanks

Susan
