Hi! I ran into this really annoying problem where we get this error message when installing a tentacle on a server in DMZ:
“Error: The requested operation cannot be completed. The computer must be trusted for delegation and the current user account must be configured to allow delegation. (Exception from HRESULT: 0x80090345)”
I found four threads in the forum here but none really solved the problem (at least for us).
Today our operations team found a possible solution to this problem. It seems to be related to that the masterkey can’t be handled properly in some way when in DMZ:
“To work around this problem, set the value of the ProtectionPolicy registry entry to 1 to enable local backup of the MasterKey instead of requiring a RWDC in the following registry subkey:
I’m not sure what the side effects are for setting this key so tread with caution.
