Unser internes Netzwerk ist auf einem hohen Level bezüglich Sicherheit. Netzwerk-segmente, Policies, etc. sind sehr stark eingeschränkt.
Bei der Installation des Exchange Hybrid Agents stoss ich auf folgenden Fehler:
Die Fehlersuche startet ich im lokalen Eventlog, und wurde fündig:
An account failed to log on.

This event is generated when a logon request fails. It is generated on the computer where access was attempted.
The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.
The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network).
The Process Information fields indicate which account and process on the system requested the logon.
The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.
The authentication information fields provide detailed information about this specific logon request.
- Transited services indicate which intermediate services have participated in this logon request.
- Package name indicates which sub-protocol was used among the NTLM protocols.
- Key length indicates the length of the generated session key. This will be 0 if no session key was requested.«Logon Type 2» bedeutet gemäss Microsoft «Interactive (also known as, Logon locally)». Schnell hatte ich den Verdacht, dass die GPO’s der Microsoft Security Baselines dies verhindern. Und so war es auch:
«Lokal anmelden zulassen» ist nur für «VORDEFINIERT\Administratoren» zugelassen
Wir haben den Service-Account für die Einrichtung durch den Hybrid-Wizard temporär zu den lokalen Administratoren hinzugefügt. So müssen wir die MSFT-GPO’s nicht anpassen, und die Security ist weiterhin gewährleistet, ohne zusätzliche Rechte.
