Trying to do updates to a client DB we have discovered that the System Functions -> Configuration Functions ConnectionProperty() is not present in any of the database instances on this server. How does one go about adding that to the server?
Thanks in advance,
John G.

You don't really and having it missing is very strange.
Did you try having a sysadmin executing something using that function - just something like:
SELECT CONNECTIONPROPERTY('net_transport')
Are you sure it's not just hidden through Tools - Options - Environment - Startup. I'm not even sure if hiding system objects would do that - just another thought.
Did you run DBCC CHECKDB?

I've never heard of it being unavailable. I don't think it requires any special permission to query it. Does the server work at all?

I don't know that ConenctionProperty is actually database functionality . function. it's server functionality related to the connection, right?

this works in SQL2008 and above, and I just checked, and it doesn't get affected by compatibility level either:

SELECT ConnectionProperty('net_transport') AS 'net_transport', ConnectionProperty('protocol_type') AS 'protocol_type', ConnectionProperty('auth_scheme') AS 'auth_scheme', ConnectionProperty('local_net_address') AS 'local_net_address', ConnectionProperty('local_tcp_port') AS 'local_tcp_port', ConnectionProperty('client_net_address') AS 'client_net_address', ConnectionProperty('physical_net_transport') AS 'physical_net_transport'
