I created a separate new selection list for the new SQL server and it works just fine.
I have tried creating a new selection list then merging the old one into it but that
dosn't work either. It seems very strange as I have not had this problem until now.
Currently I have several selection lists backing up multiple servers so why I can't
seem to get these two servers added in the same selection list just baffles me.
I really don't want to have to put it in its own list as I want to backup both servers
with the same job.
