Cant start User Profile Sync Service

Question

I have tested below condition and everything in right place but still I am not able to start the services

1. You must run the UPA Service Instance as the Farm Account.
2. Farm Account must be a local administrator of the machine running the UPA Service Instance during provisioning only.
3. Farm Account must have Log on Locally rights.
4. The Synchronization Connection Account must have Replicating Directory Changes..
5. Sharepoint webservices application pool started in IIS.

During the start process it get this error.

UserProfileApplication.SynchronizeMIIS: Begin setup for 'Hamra User Profile Service'.
ILM Configuration: Configuring database
UserProfileApplication.SynchronizeMIIS: Failed to configure MIIS post database, will attempt during next rerun. Exception: System.Runtime.InteropServices.SEHException (0x80004005): External component has thrown an exception.

 at Microsoft.Office.Server.Administration.UserProfileApplication.SetupSynchronizationService(ProfileSynchronizationServiceInstance profileSyncInstance).
UserProfileApplication.SynchronizeMIIS: End setup for 'Hamra User Profile Service'.

After it fails i get this error

User Profile Application: SynchronizeMIIS encounters an exception: System.NullReferenceException: Object reference not set to an instance of an object.

If it is still not provisioning even after a reboot, I'd delete the UPS App and start over from a clean configuration. http://blogs.msdn.com/b/jamesway/archive/2011/05/23/sharepoint-2010-clearing-the-configuration-cache.aspx
