Only one endpoint of this type is supported. Use ALTER ENDPOINT or DROP the existing endpoint and execute the CREATE ENDPOINT statement. Msg 7807, Level 16, State 1, Line 1 An error ('0x800700b7') occurred while attempting to register the endpoint 'AAA_Mirroring_Prod'. Command I'm using to create endpoint, this is at the witness server. CREATE ENDPOINT [AAA_Mirroring_Prod] AUTHORIZATION [XXXaaaa] STATE=STARTED AS TCP (LISTENER_PORT = 5024, LISTENER_IP = ALL) FOR DATA_MIRRORING (ROLE = WITNESS, AUTHENTICATION = WINDOWS NEGOTIATE , ENCRYPTION = REQUIRED ALGORITHM RC4) I'm using unique EndPoint names .
