Thanks for your reply. I tried what you suggested, but it reported back that the Current Setting for the Published option is 'Off'.
sp_dboption 'DatabaseX', 'Published'
Just to make sure, I also checked the 'merge publish' option even though we use transactional, and it was 'off' as well.
Any other ideas? In order to get our testing underway, I went ahead and dropped the database, created a new empty database, and copied all the objects over, but it took about 4 times longer than the backup/restore option (50 min vs. 12min, so not terrible, but not ideal). It also failed at the very end without a good error message, and of course, I had not thought to put an error log on the job. It appears that all the objects are there, but I'm not comfortable with the fact that it failed. I had to use the Copy Object wizard with the 'copy all objects' option, because, apparently, the copy database wizard cannot be used on replicated databases either. When I tried, that database was not available to select and the description said 'replicated database'.
