Script di esempio : script powershell classico del firewall di Microsoft Teams

• Si applica a:

  Microsoft Teams

Questo script di esempio, che deve essere eseguito nei computer client nel contesto di un account amministratore con privilegi elevati, creerà una nuova regola del firewall in entrata per ogni cartella utente trovata in c:\Users. Questa regola impedisce all'applicazione di chiedere agli utenti di creare regole del firewall quando effettuano la loro prima chiamata da Teams.
