Shilpa
Thanks for the feedback.
1. I've made the registry change and will test
2. I've tested before will AV and Anti Spam completely turned off - but is made no difference
3. I've tried backing up different numbers of mailboxes, sizes of mailboxes etc. in the past. Generally speaking - the less data backed up, the lower the likelihood of the job engine service failing - but I've had it fail on these smaller backups as well.
4. I've looked at DRWTNS32.log, and have extracted the following section. Could you have a look and see if it gives you any indication of what is happening?
Thanks, Colm
