Terminal Service License on Multiple Subnets

[Will]

I have multiple subnets in a Foreset configuration where
my TS license server is running on a DC in the root
domain. This DC TS License server serves all child domain
terminal session. I have a subnet behind a firewall that
cannot connect to the terminal server license server. I
thought I had all windows communication ports available.
What protocol/ports are used to establish a connection
from a member server running TS in Application mode to
the license server?
Thanks,
Will

You'll have to specifically point the TS to the LS.
These articles explains the details:

Thanks but there are no ports mentioned in those
articles. I've tried to sniff and I can't see anything
even attempting an LDAP request, RPC SMB or anything type
of bind my root DC. I can Bind to and Query and even
connect to with TS License Root DC, which is an
Enterprise TS License server. According to one of the
articles the member server is suppose to perform a LDAP
query. I can browse that vaule from ADSIedit from the
machine that is failing to connect to the TS License
server. Can you shed any light on the guts of the
discovery process so I can have an idea where and what to
look for?
