Renewing machine-account password does not update the serviceId for associated ntlm-auth. Because of this issue, you might see the following symptoms: -- End users report that they cannot access email. -- NTLM logons stop working for all users. -- Log file shows errors similar to the following: err nlad[12384]: 01620000:3: <0x566d4b90> nlclnt[71601c70a] init: Error [0xc000006d,NT_STATUS_LOGON_FAILURE] connecting to DC.
End users will be unable to connect.
This occurs when the system has an NTLM machine account configured, but it is not known exactly what triggers the error. It can be triggered if the machine account credentials change, but the symptom might not show up for days since the connection can be reused.
Correct the problem by running the following command: bigstart restart eca.
