Installing the Lookup Service on a Separate Server
105
For best results, connect each system running the Service Framework to the Lookup Service
manually via the Workgroup Properties tool. This technique is called Unicast Discovery and is
described in “Connecting Systems Directly to the Lookup Service” on page 106. Unicast
Discovery ensures a direct connection to the Lookup Service.
Technically there is no need for Unicast Discovery on a local subnet that contains a Lookup
Service. Unicast Discovery ensures connection to the Lookup Service but takes extra time to
configure on a large workgroup since you have to make the connection manually on each system.

The Avid Service Framework installer has an optional service named Multicast Repeater that
can be used to communicate across subnets. Multicast Repeater is no longer recommended
because it relies on a single point of communication across the subnets.
When working with multiple subnets, use Unicast Discovery on the remote subnets. Unicast
Discovery allows for fast registration and discovery operations for systems on remote subnets.
n
If you use more than one Lookup Services, use Unicast Discovery to connect to both Lookup
Services on each machine.
Interplay System Configuration Service
Use the Interplay Service Configuration tool to check for occurrences of the System
Configuration Service on any of your Interplay servers. This service should only run on the
systems that contain the Lookup Service. Use the Workgroup Properties tool to disable the
service on any other servers.
n
The System Configuration service is different from the Service Configuration tool. The Service
Configuration service runs the Interplay Service Configuration tool and can be installed on any
system running the Service Framework.
Configuring Lookup Servers on Avid ISIS
Avid recommends that you single connect the LUS using the following guidelines:
Single connect a LUS to each VLAN. In this case, use Unicast Discovery as follows:
- On each LUS system, open the Workgroup Properties tool, click the Lookup tab, and
enter the fully qualified domain name of the other LUS system.
- On each client, open the Workgroup Properties tool and specify the fully qualified
domain name of both LUS systems.
The Interplay router needs to have a route configured between the two VLANs.
n
Do not dual connect a LUS. To achieve redundancy, it is better to single connect a separate LUS
to each VLAN.
