After working for about 30 minutes (delivering the snapshot) the replication
failed

I checked the Session details of the subscription and I found Action Message
saying the 'The process could not deliver the snapshot to the Subscriber.'

In the error information under Data Source I found the following message
'General network error. Check your network documentation.'

Checking the network log I got the following message: SQL Server Scheduled
Job 'SERVER\SERVER1-MRN1-MRN1_rep-XYZSERVER.ABC.LOCAL-12'
(0x97E3EAE1F1106144B16C808A6492CB9C) - Status: Failed - Invoked on:
2006-09-28 20:23:00 - Message: The job failed.  The Job was invoked by
Schedule 35 (Replication agent schedule.).  The last step to run was step 3
(Detect nonlogged agent shutdown.).

Any clue?
