When trying to do a database mirror, I get the attached error after I go through the wizard. Note that during the wizard everything connects just fine between servers and I get the green checkmarks at the end of the wizard. When I click start mirroring, the attached error comes up.
Any ideas? Here is the sql statement I used to create the endpoints:
CREATE ENDPOINT [Mirroring]
AS TCP (LISTENER_PORT = 5022, LISTENER_IP = ALL)
FOR DATA_MIRRORING (ROLE = PARTNER, AUTHENTICATION = WINDOWS NEGOTIATE
, ENCRYPTION = REQUIRED ALGORITHM AES RC4)
