Virtual Server Replication in Cloudmin

I have Cloudmin for physical system. finally got round to using it for server replication which is superb :)

I wish to be able to set up a pointer to b.domain.com as my backup server. I have set up a DNS record using 'b' to poin to my backup IP.

the replication has worked and the DNS records have been updated on backup server. everything has also been copied over so that is great.

however, when I go to ' b.domain.com' it goes to my backup servers web page and not the actual domain itself. what am I doing wrong ?

thanks for any advice
