<p>Open ADSIEDIT and look in the following snapshot. Open Configuration for your DC</p>



<p>Collapse the menu and click on Services</p>



<p>Click on RTC Service</p>



<p>Click on Global Settings and on the right pane look if there&#8217;s any duplicated entries and remove them.</p>



<p>As you can see on my right pane I have 2 duplicated (msRTCSIP-EdgeProxy) and I&#8217;m going to remove one of them and see </p>



<p>if I can publish my topology or not. But before that I will have to make sure that I export the entry that I wanna delete.</p>

<p>Now I will try to publish my topology and see what happens, my topology publishing failed with </p>



<p>a new error this time.</p>

<p>I will have to go and check where&#8217;s this coming from, since it mentions TrustedService. I will go look in the trusted service</p>



<p>This is not going to be easy, as you need to be careful where you look .. You will need to make sure that you&#8217;re looking</p>



<p>at the right FQDN</p>



<figure class="wp-block-image"><img src="https://lh5.googleusercontent.com/Eb1QhrEGvBXkY4twIYueIRbDP2qFRTdAD0kE8ngpPf4zu0eQFqhL22QxIoWkgeloaNG1pB4oL9csIofm8n7g0PIWCKKlpTjn-Tg_Mz8apS_jLs5o5WQ=w1175" alt=""/></figure>

<p>Here I could find the value MRAS for the FQDN Edge server</p>



<p>So I looked here and found 2 identical entries with a different (CN) if you scroll down you will see that the GruuId is the</p>



<p>same, FQDN is the same, port is the same.</p>

<p>Let&#8217;s delete one of them and see again if we can publish our topology, So I deleted the one that starts with {b344}</p>



<p>I will do this using the Lync Powershell, you can see below that the Topology was published successfully.</p>

<p>To resolve the warning you will have to issue the cmdlet Enable-CsAdForest after the Enable-CsTopology</p>
