JOB RUN: 'REPL:1001' was run on 3/23/2007 at 3:00:01 AM
DURATION: 1 hours, 11 minutes, 11 seconds

MESSAGES: The job failed. The Job was invoked by Schedule 421 (Replication agent schedule.). The last step to run was step 3 (Detect nonlogged agent shutdown.).

Please see below for the description of my Replication Job:

1. Distribution Agent startup message.
db: distribution
cmd:
sp_MSadd_distribution_history @perfmon_increment = 0, @agent_id = 126, @runstatus = 1, @comments = 'Starting agent.'
2. Run agent.
cmd:
