Skype for Business Server Topology Builder encountered an issue and cannot publish this topology.

ERROR

The error message given below mostly appears when you trying to publish the topology for the very first time.

Topology Builder encountered an issue and cannot publish this topology.

SQL store \rtc is not defined in the topology. You must ensure that the SQL store that is used for the Central Management Store is part of the defined topology and that the SQL store is associated with a Front End Pool.

SOLUTION

1. Open Skype for Business Server Shell on the new Skype for Business Server role that you have deployed

2. Run Get-CsConfigurationStoreLocation. This cmdlet reports back the location of the Active Directory service control point for the Central Management store.

If the output of the above cmdlet is same as that of the SQL server and instance shown in the error above,

3. Run Remove-CsConfigurationStoreLocation cmdlet. The account running the cmdlet must be a member of RTCUniversalServerAdmins group.
