You need to create a separate instance. The main reason for this is because you cannot specify the name of the database instance so structurally, it needs to be in a different instance. Other services such as archiving can use the same instance as a pool but if you are encountering performance issues, Microsoft will not support it.javascript:%20postComment(1);

Great resource, thank you for sharing it. I have a question regarding the back end. Can I install two different Enterprise Pools in the same SQL server same instance? or do I need to create a new instance as the DB's already exist for an existing pool?

Hi Elan,

thanks a lot for your nice documentation – great.

I have a question about the coexistence of LCS (Live Communication Server 2005) and OCS 2007 R2:

My plan is to install OCS 2007 in the same domain and leave LCS 2005 as it is, so that I can test the new OCS 2007 installation, until I change the SIP Server for all users by GPO.

Can I have OCS 2007 and LCS 2005 in the same domain?
By installing OCS 2007, do I need to extend the Active directory (an other pre installation steps) and which global store settings I should use (System container in root domain OR Configuration container)? I don’t want to overwrite the LCS configuration by the OCS 2007 installation.

Thanks a lot

Erik

Hi, this is a fantastic tutorial.
I have a problme installing the ocs server.
When i install the pool everything is shown as success in the report, but the pool ready state is on false.
Do you have any ideas?

You should be able to change the ports as you see fit just as long as the ports are different for each service hence why are you given the option in the GUI to modify the ports. I would suggest downloading the firewall diagram in the OCS R2 Technet Library and tweaking that to have the ports you want and then modify that in the GUI.

Elan,

Got a question about ports ranges in OCS, our network team that is setting up the Load Balancer keep coming back with questions about can we change the ports that clients talk back to the server on. Like IM conferencing & telephony conferencing ports 5062 & 5064 for example. There having a hard time with all the ports OCS requires and would like to see if we can change them to the same port. I don’t see how it will work but just thought I would get your thoughts.

Thanks in advance
Anthony

Yes, that’s fine. It’s how I set up my article’s lab. I used a primary AD integrated zone that was not our AD zone. exchange.shudnow.net is the SIP domain and is not the name of the domain.

Elan,
Thanks very much for the detailed walkthrough. A previous post commented on using a primary (not AD) DNS zone as a pool. Is this possible? I’ve tried it myself and received “Failure – the specified domain does not exist or could not be contacted.” The zone I used is a primary, AD-integrated zone, but not our AD domain.

Appreciate your work!
