Hi,
If you are using a clustered instance of SQL then you will need to use another SQL server/instance, If not then the source SQL should be able to verify the DB ok. The latest version of SMSQL, v5.1 will allow you to use a clustered instance of SQL to verify DB's.SMSQL5.1 will allow you verify the DB at the remote site, I don't think v2.1.1 will allow this.
hope this helps
Andy
