SCCM 2007 Won't remove Distribution Points in Site Status

Question

I'm working SCCM 2007 and have removed  some orphaned Distribution Points by going through and removing any application assigned to them and then removing the roles under the Site Systems Folder.
The Systems then disappeared from under Site Systems but when I look under Site Status, they're still appearing in the list there and I have no option to delete them.
I've tried following this link (http://myitforum.com/myitforumwp/2012/02/10/removing-old-orphaned-site-systems-from-the-sms-and-configmgr-2007-database/) and changing their replication field from a 0 to -1 which removes them temporarily but they always return
into the Site Status.
I can't see them anywhere else in the console, they're definitely not sited under Site Systems so I'm a bit stuck and have 3 sites saying they're in a Critical State in Site Status because the Orphaned Distribution Points are still appearing there and I
can't see how to remove them.
To clarify, I removed the orphaned Distribution points over a week ago so I doubt it's something like waiting for the system to e them.  I've tried rebooting the SCCM server and this has made no difference
My list of servers under Site Systems;  
My Servers in Site Status;

Answer 1

Execute the following command on the database
Delete from DPinfo where server name like '%DPName%'
It is completely unsupported to delete anything from the CM07 database. Before doing this you should contact CSS directly for support and ONLY with their guidance should you perform this task.
