When publishing our Lync Topology

When publishing our Lync Topology I'm getting the following error on the Enabling Topology step:

Error: Found multiple objects with identity "lyncFE01.lynclab.local,McxInternal" in Active Directory. ▼ Details └ Type: ActiveDirectoryException └ ▼ Stack Trace └ at Microsoft.Rtc.Management.Deployment.Core.CompatTrustedService.GetTrustedService(ADSession session, ADObjectId containerId, String fqdn, String serviceType) at Microsoft.Rtc.Management.Deployment.Core.CompatTrustedService.Create() at Microsoft.Rtc.Management.Deployment.Roles.WebServices.GlobalActivate(IService service, Computer computer) at Microsoft.Rtc.Management.Deployment.Core.Service.GlobalActivate(Computer computer) at Microsoft.Rtc.Management.Internal.Utilities.LogWriter.InvokeAndLog[T](Action`1 action, T arg)

Solution
1) Run Test-CsTopology -Report C:\temp\testtopology.html

2) Prepare the appropriate AD for a TXT file:Ldifde -f c:\temp\addif.txt -s DC_FQDN -d "CN=RTC Service, CN=Services, CN=Configuration, DC=lynclab, DC=local"

3) Find the duplicate entries in txt file. Then delete them from AD using ADSIE Edit
