Hello @Anonymous,

I found this in a post on the forum:

Need to do this to fix the problem:

Create or set a new registry DWORD value, named ProtectionPolicy, value 1, to enable local backup of the MasterKey instead of requiring a RWDC in the following registry subkey:

HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb

1. Hit Windows + R

2. Type regedit and hit enter

3. Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Cryptography\Protect\Providers\df9d8cd0-1501-11d1-8c7a-00c04fc297eb

4. In the folder, right click and hit New > DWORD (32 Bit) Value

5. Name it 'ProtectionPolicy'

6. Right click 'Protection Policy'

7. Hit Modify and change the value to 1 and select Base: Hexadecimal

Hope this helps.

Robert,

     This did not help the situation the "Default External Servers Not Available" screen is still opening when I open Revit. Do you have another solution?
