I have a MS-SQL instance configured to be a CMS for 50+ instances of MS-SQL Server 2008-2017. When checking the msdb.dbo.sysmanagement_shared_registered_servers_internal I see a list of the servers and their associated groups.
However when I connect to the instance remotely (from my Desktop via SSMS), the Registered Servers list only displays an offline SQLExpress instance in "local server groups" associated with my local PC - and nothing at all under "Central Management Servers".
When RDP'ing to the CMS directly, in SSMS the Local server group correctly shows the CMS instance under "Local Server Groups" but it's empty - and again, "Central Management Servers" is empty.
Any help on how to usethe existing CMS server list would be appreciated, as rebuilding it would take some time and I'm unsure on any side effects of essentially overwriting another CMS configuration on top of the existing one.
Note: I didn't build the existing CMS nor have I used it previously.
