Thanks for the help. I was able to run lcscmd /domain:x.com /action:unprepdomain and forest.<br />
<br />
The domain unprep completed successfully and the forest unprep required a /force for it to work. <br />
<br />
The &quot;Live Communications Address&quot; field no longer is present in ADUC. I was unable to find the CN=RTC Service under the domain configuration in ADSI Edit. However, I can still see a bunch of CN=ms-RTC attributes listed under Schema in ADSI edit. Is it safe to delete all these? We have no OCS servers installed in our domain. Just exchange 2003.<br />
<br />
<br />
Thanks!

Thanks again for all your help. I think I'll just leave the schema alone. It doesn't appear to be hurting anything.

<div class="content wysiwyg-content">
I am going through our current AD structures (Windows 2003 native no R2), and I keep finding old traces of when an Live Communications Server 2005 was installed, but never removed. A previous employee installed it and the server crashed so it was never properly removed from the domain. What must be done to remove all the attributes (ie: Live Communications Address) from AD ? I can see a lot of msRTC schema attributes still there from the schema editor.<br />
<br />
Anyone have any ideas?<br />
<br />
Any help is greatly appreciated!<br />
