Lync 2010 – Operation was unsuccessful

When you installed Lync did you add the CSAdministrator and RTCUniversalServerAdmins to your Administrator Member Of Security group?

Without CSAdministrator you cannot log into the Control Pannel, and without RTCUniversalServerAdmins, you will have some trouble in doing some advanced powershell stuff.

I have had the same experience trying to connect a CX600 that has never connected to a Lync server. I have used Jeff Schertz's Blog extensively in an effort to configure this.

I too noticed the VLAN ID of 1 (default) and found a post by Jeff on how to set this for Lync. However I did not have success with this, once configured per the Blog entry, the phone could no longer get an IP address from DHCP. What we did see was that based on the error code the phone listed, 2f0d, the issue seemed to have something to do with Lync not trusting our private CA. We tried swapping out our private cert for a wildcard cert issued by CA that is trusted by Lync and were then able to connect to our Lync server and the phone updated to the latest firmware after a few minutes.

As I've read a number of post telling that wildcards will not work, it was a surprise to us that this was the work around. We'd like to use the private cert, but have not found a way to do it yet.
