| Issue | Severity | Explanation | | :--- | :--- | :--- | | | Medium | Forcing thousands of clients to re-download all policies simultaneously can spike network traffic and slow logins. | | Boot/Login Lag | High | On a slow link or with complex policies (Folder Redirection, AppLocker), /force can add 30-60 seconds to login time. | | Security Filtering Side Effects | Medium | Overwrites security group memberships dynamically. If a user was temporarily added to a restricted group, /force may remove that access instantly. | | No Server-Side Check | Low | The client reprocesses policies even if the server's GPT.INI shows no change. This is inefficient but not harmful. | Insufficient permissions for computer-level policies
