SCCM 2012 için geçerlidir SQL 2012 kullanılıyorsa.

Central ve Prmimary Site arasında replication sorunu çıkabilir bu patchi yükledikten sonra: KB2840628/MS13-052
Remctr.log da bunu görebilirsiniz:

The asynchronous command finished with return message: [A .NET Framework error occurred during execution of user-defined routine or aggregate "spDRSActivation": ~~System.TypeInitializationException: The type initializer for 'System.Data.SqlClient.SqlConnection' threw an exception. ---> System.TypeInitializationException: The type initializer for 'System.Data.SqlClient.SqlConnectionFactory' threw an exception. ---> System.TypeInitializationException: The type initializer for 'System.Data.SqlClient.SqlPerformanceCounters' threw an exception. ---> System.MethodAccessException: Attempt by method 'System.Configuration.TypeUtil.CreateInstanceRestricted(System.Type, System.Type)' to access method 'System.Diagnostics.SwitchElementsCollection..ctor()' failed. ---> System.Security.SecurityException: Request failed.~~System.Security.SecurityException: ~~   at System.Security.CodeAccessSecurityEngine.ThrowSecurityException(RuntimeAssembly asm, PermissionSet granted, PermissionSet refused, RuntimeMethodHandleInternal rmh, SecurityAction action, Object demand, IPermission permThatFailed)~~   at System.Security.CodeAccessSecurityEngine.CheckSetHelper(PermissionSet grants, PermissionSet refused, PermissionSet demands, RuntimeMethodHandleInternal rmh, Object assemblyOrString, SecurityAction action, Boolean throwException)~~   at System.Security.PermissionListSet.CheckSetDemand(PermissionSet pset, RuntimeMethodHandleInternal rmh)~~   at System.Security.PermissionListSet.DemandFlagsOrGrantSet(Int32 flags, PermissionSet grantSet)~~   at System.Security.CodeAccessSecurityEngine.ReflectionTargetDemandHelper(Int32 permission, PermissionSet targetGrant)~~System.MethodAccessException: ~~   at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached~~      ...~~System.TypeInitializationException: ~~   at System.Data.SqlClient.SqlCommand.ExecuteNonQuery()~~   at Microsoft.ConfigurationManager.DataReplicationService.DatabaseOperation.ExecuteNonQuery(String commandText)~~   at Microsoft.ConfigurationManager.DataReplicationService.MessageHa...].

 

Şu an sorun çözülmüş değildir ama workaround olarak bunu yapabilirsiniz.
Patch yüklü kalabilir ama SQL içinde bu değişkliğe gidilmesi gereklidir:
