This will be the first part of many in showing the steps necessary for standing up an OCS 2007 server. In the examples that follow the internal domain name is ptown.com and the SIP domain, or my external facing address will be confusedamused.com

tap-dc-2k3.ptown.com

  • Domain Controller for ptown.com
  • DNS Server for ptown.com
  • Certificate Authority named P-Town Certificate Authority
  • Domain in 2003 Native Mode
  • IP Configuration: 192.168.0.10 / 24
  • Gateway: 192.168.0.1
  • DNS: 127.0.0.1

tap-ocs-2k7.ptown.com

  • Blank Windows 2003 Server joined to the ptown.com domain
  • IIS Installed with ASP.net enabled

That concludes Part 1 of this series. Not very interesting yet, or hard to screw up either. The other parts should be much more interesting.

    Thanks for this post. I too am going through OCS 2007 deployment and am amazed at how heavy the documentation is and how confusing the advanced configuration is. I’d be very interested in keep track of this blog and maybe even collaborate a little?? :-)

    Thanks Joe

    I just attempted an install, but not sure of best design. I would like to also have external connectivity for LiveMeeting and not sure of design. I could not see some of your photos, but I did screen captures during my install and most look the same. Keep me in the loop and I too would be willing to collaborate.

    Thanks, Steve

    Any ideas on why the RTCComponentService account would fail to create. I have been banging my head on this for a few days. Everything seems ok. I dont want to make the account manually because i am not sure what groups it needs to be in.

    Joey, I had the same problem, try entering a password without blank spaces and maby another extrange character.

    The internal server installation is quite easy wait till you try outside connections!.

    I’ve been trying to get edge server, isa server all working for the last 8 weeks but using the Microsoft documentation it is not easy. Probably have to give up and use another solution?

     
  6. 7 Tom Pacyk

    The Edge pieces definitely give people more trouble, but I can assure you that it’s possible. I’ve done quite a few implementations now with Edge Services via ISA or other firewall solutions.

    I never got around to fully documenting the Edge setup here, but you may want to check out Elan Shudnow’s site as he has some great tutorials there.

    There’s also an article on ISAServer.org that I co-authored on publishing OCS through ISA 2006 at http://www.isaserver.org/tutorials/OCS-2007-ISA-2006-Firewall-Design-Architecture.html

    great site walkthrough here. However, when i tried to install the Enterprise edition, I had a a failure as there are several differences on the installation and I got lost. One thing to take note of is that my AD doesn’t show the “Enable user for Communications Server”. Why? The preps for schema, forest, and domain ran successfully. Please provide some insights. Thanks again!

    Nice one here, i am a bit confused on the external SIP domain. please what is this all about and how can i get it? more so, how do i make others outside the network connect to it?
