I have Groupwise 2014 installed using two domains. A primary and Secondary, each on separate servers. Both are operating and connecting and for all intensive purposes working. I get the following error when connected to the primary domain admin page and I try and connect to the secondary domain.

Domain Admin Service might be down. Check the IP Address and Admin Port on the MTA.
If I do the same thing from the admin page from the secondary domain server, I can switch between domains without any problem.

I know for a fact the admin service is not down and I can connect to both. The secondary domain components in the admin page of the Primary domain server are also all active and editable.

Both servers are OES11 SP2

Any ideas?
