Just had a small issue trying to publish Lync 2013 Topology where it would appear that the Lync Server 2013 CU1 update duplicated all the 2013 FE Server MSRTCSIP-TrustedService entries for the UCWAInternal and UCWAExternal services. Everything looked fairly good until it came time to enable-cstopology. Here is the error we got.
“Multiple Active Directory entries were found for type “MS-RTC-TrustedService” with ID of fqdn.domain.com/UcwaExternal.
Fixing ONE of these resulted in the next item on the list being found and then erroring out.
I went through and renamed the service names on all 4 FE servers to update so the enable-cstopology only saw one valid entry. This was needed on three (3) Enterprise FE nodes and on an SE FE server in the environment.
Will update this accordingly if this proves to have borked up something else. Why this occurred is not known to me, other than running the CU1 updates into the environment.
