On a new Skype for Business Server 2015 deployment, the following error occurs when trying to download the current topology using Topology Builder.
“Topology Builder could not copy the topology from the Central Management store. Unable to read the topology. Please verify that the topology data is accessible before trying this procedure again. If you are using Always On with your Central Management Store database, please verify that Always On has been enabled”.
- This is a Skype for Business Server 2015 Standard Edition deployment (local SQLExpress only).
- The CMS is accessible.
This is happening because of permissions on the xds database, as the user account used to install the Skype for Business Server 2015 Standard Edition Server is different to the user trying to download the current topology.
Using SQL Server Management Studio, connect to the RTC SQL Server Instance, in this case I’m connecting to the RTC instance on the Skype for Business Server 2015 Standard Edition Server (e.g. SFBSRV01.x500.co.uk\RTC).
Expand the xds database.
Expand Security, right click Users, select New User.
Add the user or group who needs to perform this task, here I am adding the CSAdministrator AD group.
Assign the user the db_owner permission.
This will resolve the issue, retry downloading the current topology.
