During a Lync 2010 install, in the section for publishing your topology, I got an error while creating my Central Management Store
Error in the logs were:
Error: An error occurred: “Microsoft.Rtc.Common.Data.SqlConnectionException” “A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 – Error Locating Server/Instance Specified)”
After doing a bit of research this is caused by Windows Firewall. Just shut it off and try again and it should work fine.
