For my labwork, I always virtualize. Keep in mind though, that most roles for virtualization are not supported and should not be done in production. This does not mean that you cannot, just that you risk having issues and/or not receiving support from Microsoft.

Make sure your time is in sync, timezone is set correctly, Also, make sure that you are not using some extensive password with not so typical passwords as I have seen this break an install. Also, you may want to try running the ocsanfix.exe as I have seen that break certain parts of an install process. That exe is located from here: http://support.microsoft.com/kb/974571

Hope that helps

But, I do have one problem, which is i have received this “distribution group service could not perform this action” when i’m using ISA Server 2006 as a proxy for my IE. If i removed it(and using Cisco Transparent Proxy), office coomunicator able to retrieved the distribution group.

Hope U may help on this on how to change the setting at ISA Server to allow distribution group is retrievable.

Could someone in this world please help me with the questions I have as follow:

I do not have a 64 bit machine. Is there any possibility of installing,OCS 2007 R2 on Server 2003 x86?
Can I do it on virtual Machines?
Can I download OCS 2007(not R2) from anywhere?
What could be the possible interview questions, any tips?

Thank you in advance.

You can run them in VMs. OCS 2007 has no virtualization support and OCS 2007 R2 has some virtualization support. You can read the virtualization support policy here: http://communicationsserverteam.com/archive/2009/...

You can download OCS 2007 R2 Evaluation here: http://technet.microsoft.com/en-us/evalcenter/bb6...

More documentation here including a doc specific to OCS Administration: http://www.microsoft.com/downloads/details.aspx?f...

Hope that helps and good luck on the interview.

Thanks for all the info, it has been really useful.

I have a question regarding Edge services. We are a fairly large organisation that shares a secure external WAN with other similar organisations with which we would like to federate. We also need to enable external client access and possible federation with external partners from the Internet. Is it possible to support this configuration i.e. communication via the external WAN where available, otherwise via the Internet? If so, how is this best achieved?

Great article, Currently planning to deploy OCS Server and Exchange 2010 for small business client, I think a guide which combines these as full unified communication solution would be very helpful to our community.

I just created a lab for it to start with it.

Thanks
