Prompt user when slow link is detected
Computer Configuration\Administrative Templates\System\Logon
Notifies users when their roaming profile is slow to load. The notice lets users decide whether to use a local copy or to wait for the roaming user profile.
If you disable this policy or do not configure it, when a roaming user profile is slow to load, the system does not consult the user. Instead, it loads the local copy of the profile. If you have enabled the Wait for remote user profile policy, then the system loads the remote copy without consulting the user.
This policy and related policies in this folder together define the system's response when roaming user profiles are slow to load.
If the Do not detect slow network connections policy is enabled, this policy is ignored. Also, if the Delete cached copies of roaming profiles policy is enabled, there is no local copy of the roaming profile to load when the system detects a slow connection.
To adjust the time within which the user must respond to this notice, use the Timeout for dialog boxes policy.
