I have a situation where we have a Lync 2010 environment with a trusted application setup for CWA.  However, we are no longer supporting the use of CWA so I would like to properly remove it from our environment.

Normally this would be a simple matter of deactivating CWA.  However, one of the CWA servers got shutdown and deleted during some sort of clean-up process without our knowledge.  Is there a safe way I can make sure that machine is removed from AD properly (as if it were deactivated) so it does not cause any conflicts down the road?

I was planning to remove the trusted application from the Lync Topology then deactivate the remaining CWA server.

Any help is appreciated.

Thanks.

I think you're on the right track.  If it was removed from AD already, the only step left would be to remove it as a trusted application server.  Just kill it from the topology and run get-Cstrustedapplication to make sure everything is gone when you're done.

Hi,

All of the virtual servers created on the Communicator Web Access server must be deleted before you can deactivate a Communicator Web Access server.

Deactivation also removes the server from the Communicator Web Access snap-in. However, this does not delete the Communicator Web Access files from the computer. To do that, you need to uninstall the software by using either Programs and Features (that is, on Windows Server 2008) or Add or Remove Programs (that is, on Windows Server 2003).

You can refer to the link below of Deactivating a Communicator Web Access Server:
