In Client Automation if you look in All Computers the agents shows which Scalability Server it is connected to, sometimes it will show the IP address instead of the Name.
Why does some Scalability Servers come with IP Address where others have the Server Name?
Sometimes when you register a Scalability Server to a Domain Manager, the Domain Manager reaches back to the Scalability Server to get the FQDN to register the machine. If it can not get the name it will register the machine with the IP address.
To resolve this you can fix your DNS issues
Add a Windows Host entry, for example: (%windir%\system32\drivers\etc
<ip_address> <Short Name> <Fully Qualified Domain Name>
Then unregister the Scalability Server, from the Scalability Server type: cserver unregister
Then register the Scalability Server, from the Scalability Server type cserver register -a
Now the Scalability Server should have the the Fully Qualified Domain Name.
