Resolution
=========

Somehow the SQL Instance information for the FIM Synchronising Service is missing

To resolve the issue add the SQLInstance name to the following Reg key:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINESYSTEMControlSet001servicesFIMSynchronizationServiceParameters]
"SQLInstance"="<InstanceName>"
