Connection Handshake Failed - Easiest Possible Configuration

Hi there!

Often discussed, but not really solved in my opinion - the connection between the partners and the witness causes problems.

My case: Three Servers in the same domain, three endpoints on 5022 with windows negotiation, all endpoints can be reached by telnet from each server. Mirrorring works. So far so good.

But one of these partners is not able to connect to the witness. The witness' error log is full with that:

"2006-06-01 13:45:20.32 Logon Database Mirroring login attempt failed with error: 'Connection handshake failed. An OS call failed: (8009030c) 0x8009030c(Der Anmeldeversuch ist fehlgeschlagen.). State 67.'. [CLIENT: 130.143.205.54]"

My Endpoints are created like

CREATE ENDPOINT [EASYRIS_Mirroring]

AUTHORIZATION [code1dephbrsaa1-sys108]

STATE=STARTED

AS TCP (LISTENER_PORT = 5022, LISTENER_IP = ALL)

FOR DATA_MIRRORING (ROLE = PARTNER, AUTHENTICATION = WINDOWS NEGOTIATE

, ENCRYPTION = SUPPORTED ALGORITHM RC4);



What catches my eyes is that

GRANT CONNECT ON ENDPOINT::EASYRIS_Mirroring TO [code1dephbrsaa1-sys108];

doesn't cause these user to appear in the result set of

SELECT EP.name, SP.STATE,

CONVERT(nvarchar(38), suser_name(SP.grantor_principal_id))

AS GRANTOR,

SP.TYPE AS PERMISSION,

CONVERT(nvarchar(46),suser_name(SP.grantee_principal_id))

AS GRANTEE

FROM sys.server_permissions SP , sys.endpoints EP

WHERE SP.major_id = EP.endpoint_id

ORDER BY Permission,grantor, grantee;

By the way, these mentioned user is sysadmin and grantor.

Has anyone an idea?
