Windows 2012R2 DC will not boot

Last Modified: 2020-01-03
VMWare ESXi 6.7
Two 2012R2 DCs.  DC1 and DC2.  
DC1 is the Operations Master RID, PDC and Infrastructure
DC1 is not booting up properly.  It hangs at spinning dots "Please Wait"
I'm able to boot into Safe Mode.

DC2 is fine.  Have not tried to boot.  Users are authenticating through DC2.

What changed:
Upgraded from ESXi 6.0 to 6.7 latest version.  This past Monday, 12/30.
Enabled GPO System cryptography: Use FIPS compliant algorithms for encryption, hashing and signing.
Upgraded VMTools but not the compatibility, stayed at 6.0
Attempted to install the VMXNET3 nic instead of E1000.  Server went bananas, so I reverted changes.  Server still would not boot.
Restored server from last night's backup through Veeam
DC1 will only boot with this Please Wait.  Unless I cut it short and boot into safe mode.

What am I missing?
