I am copying all data from a production database to a development counterpart (both SQL Server 7) weekly by means of snapshot replication, but I am mystified by the repeated disappearance of the distribution job. I use the Enterprise Manager wizard to create the push subscription on Friday, creating a distribution job in the SQL Server Agent list, the job runs on schedule early Saturday morning, and sometime between Tuesday and Wednesday the job disappears from the list. (Note: The associated snapshot job has remained in the SQL Server Agent list since I created it via the Enterprise Manager wizard three or four weeks ago.) When the wizard creates the job I review its properties to confirm that it has no end date; but, even if it had one, I would expect the job to be disabled after that date, rather than deleted. I would be grateful for any suggestions regarding the cause of this problem and how to prevent it.
