Registry Key werden nicht hinzugefügt

DeathSheep · 15. Mai

Hallo zusammen!

Wir müssen auf spezielle Art und weise ein VPN Tunnel erstellen.

Nun haben wir ein Script zusammen gestellt, welches eigentlich den Sinn erfüllt, jedoch funktioniert ein Teil nicht.

Der Anfang funktioniert - VPN Verbindung wird erstellt inkl. Route.
Dies wird mi Add-VpnConnection und Route erstellt.

Jetzt benötigen wir jedoch noch AlwaysOn. Dies würden wir gerne mit dem unten angefügten Script erstellen.
Führt man die Abschnitte einzeln aus, funktioniert es und die Registry Keys werden erstellt. Führt man Script als ganzes aus - wird kein einziger Registry Eintrag erstellt und es gibt kein Fehler-Output.

Ich habe es bereits versucht mit und ohne Transaction...
Was zur Hölle mache ich hier falsch?

Problematisch finde ich das hier:

vor 11 Stunden schrieb DeathSheep:
REG add "HKLM\System\CurrentControlSet\Services\RasMan\Config\"

Das bleibt mit "Vorhanden, überschreiben? (j/n)" stehen, wenn man's interaktiv ausführt. Was schreiben denn die ganzen Write-Verbose so in die Konsole?

Ich habe mir auch erlaubt, den Code etwas lesbarer zu machen :-)

Hallo Martin,

danke für Dein Feedback - es wird leider gar kein Ergebnis ausgegeben lustigerweise.

Habe aber gestern Abend noch ein Feedback vom MS Engineer bekommen:

Zitat

TLDR Update: Das PowerShell Script funktioniert - sobald man in der VAN/Settings UI die Option "Connect Automatically" manuell anklickt. Danach kann man sie wieder deaktiveren (Haken entfernen), dann funktioniert auch das PowerShell Script. Das liegt daran daran das beim anklicken von "Connect Automatically" einiges mehr gemacht wird als die Registry Einträge erstellen (diverse WMI Änderungen, Syscalls etc.

Scheint also so, als würde es ggf. gar nicht machbar sein.
