OP: Microsoft SQL Server 2008 R2 (RTM) - 10.50.1617.0 (X64) Apr 22 2011 19:23:43 Copyright (c) Microsoft Corporation Standard Edition (64-bit) on Windows NT 6.1 <X64> (Build 7601: Service Pack 1) (Hypervisor)
the above is the GDR patch after RTM, now when we are upgrading to SP1 the instance is not at all reported.
Any suggestions or fix for this, even shared service component also is not coming up.
