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?
Thanks
Eric.
