Slow network connection timeout for user profiles
Computer Configuration\Administrative Templates\System\Logon
Defines a slow connection for roaming user profiles.
If the server on which the user's roaming user profile resides takes longer to respond than the thresholds set by this policy allow, then the system considers the connection to the profile to be slow.
This policy and related policies in this folder together define the system's response when roaming user profiles are slow to load.
This policy establishes thresholds for two tests:
For computers connected to IP networks, the system measures the rate at which the remote server returns data in response to an IP ping message.
To set a threshold for this test, in the Connection speed box, type a decimal number between 0 and 4,294,967,200, representing the minimum acceptable transfer rate in kilobits per second. By default, if the server returns fewer than 500 kilobits of data per second, it is considered to be slow.
For non-IP computers, the system measures the responsiveness of the remote server's file system.
To set a threshold for this test, in the Time box, type a decimal number between 0 and 20,000, representing the maximum acceptable delay, in milliseconds. By default, if the server's file system does not respond within 120 milliseconds, it is considered to be slow.
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.
Consider increasing this value for clients using DHCP Service-assigned addresses or for computers accessing profiles across dial-up connections.
