    Hello

    What is the best practice for setting up and HA licensing environment for RDS?  I'm using a mixture of RDS CALs for my internal/AD users and External Connector license for my external/Internet users.

    Hi,

     

    To ensure high availability you want to have a fallback License Server in your environment. The recommended method to configure Terminal Service Licensing servers for high availability is to install at least two Terminal Services Licensing servers in Enterprise Mode with available Terminal Services CALs. Each server will then advertise in Active Directory as enterprise license servers with regard to the following Lightweight Directory Access Protocol (LDAP) path: //CN=TS-Enterprise-License-Server,CN=site name,CN=sites,CN=configuration-container.

     

    To get more details on how to setup your License Server environment for redundancy and fallback, go over the "Configuring License Servers for High Availability" section in the Windows Server 2003 Terminal Server Licensing whitepaper

    Hi,

    As RDS no longer supports license server discovery, we'd recommend that for HA in RDS environments you'd split the licenses between two or more license servers and configure the RD Session Host servers to point to them direcrty. If the first LS in the list on a RDSH server doesn't have licenses, the RDSH will go to the next.

    Hope this helps,

    Christa

    Thanks all.

    Last thing I want to confirm is about forest/domain relationships.  My RDS LS is in Forest A and I have a trust relationship to Forest B where some of my internal users reside.

    I am using RDS CALs for internal/AD users and an External Connector for my non-AD/Internet users.

    Best practice would be to install CALs and EC on the same LS servers in Forest A, and then users in Forest B would be able to leverage the LS's in Forest A assuming connectivity was in place, correct? 

    Can you confirm there is no reason why I would NEED to install an RDS LS in Forest B as long as the trust to A is config'd properly?

    thanks!

    Hi Christa,

    I have 120 VDI suite licenses and have 120 users who will be using Microsoft VDI Solution. So I have to split them 60 + 60 on 2 license servers. One question....

    * In above scenario my 120 license will be consumed by my 120 users. If one LS goes down, not sure how the second LS will provide the CAL's.

    Please can you assist me how should I configure my LS for High Availability.

    Cheers
