Hi

My company is under Mixed Mode Domain, because we still running some NT dc. I can't install OCS 2007. I found this link http://forums.microsoft.com/unifiedcommunications/ShowPost.aspx?PostID=1518641&SiteID=57 , but I can't find that document. Can anyone give me some more detail?

I tried to install LCS 2005, but I got error in Forest Prep Stage.

Global Settings: Not Ready
Failure
[0x80070057] The parameter is incorrect.

Can anyone help with this issue?

Thank you so much.

I believe this is the document you are looking for:

Configuring Office Communications Server 2007 in a Multiple Forest Environment

http://www.microsoft.com/downloads/details.aspx?FamilyId=1D7CF1E6-6770-422F-B744-E1764F5666AE&displaylang=en

It explains how you can deploy a separate resource forest for use with OCS as you can not deploy OCS in your current forest until you raise the functional level.

It means that you cannot install in a domain that has NT4 Domain Controllers or is not in Native mode

Here you can find all documentation related to OCS and you will also find the Planning Guide
