SRV Records for LCS

[Hostmaster]

When I go to add this SRV record on a W2K DNS server, it
wants me to choose a service. This paper from MS does not
explain what service to choose for LCS SIP RRs. I need to
know what service to choose from the drop down menu for a
SRV record.

To publish the SIP service in the internal DNS server, the
following DNS SRV record must be created:
Name Priority Port Target
_sip._tls.example.com 0 5061 sip.example.com
The target name can represent one or more IP addresses (A
host) of home servers or front-end servers. If the target
name includes home servers, assign a lesser number of
users to this server because it must also handle the load
of initial Register requests from users homed on different
home servers.

Well, I'm not an expert for LCS but I had the same "issue" with the Instant
Messaging
Service from EX2000.

If you want to add a SRV Record to DNS that is not available via the GUI
simply
overwrite the value in the GUI. For example:

-In DNS Manager on Zone "example.com" create a new Service Location Record.
-The default window comes up with Service "_finger", protocol "_tcp" and
port "79"
-Now simply overwrite the values for "_finger", "_tcp" and "79" with the
values
"_tls", "_sip" and "5061".
-In the "Host offering this service" field enter the FQDN of the LCS Server
-Done

Good luck

Just to add, once the _tls record is created, then will need to create the
_sip record under it (if I remember that correctly). The Exchange _rvp
record is a TCP service and it shows up in the list, that's why I believe
(don't have a server in front of me to check) that you would need two steps
to create this.
