Users who are connected to the central User Environment Manager configuration and profile archives shares over a slow WAN connection might experience slow performance and continuously roaming personal settings can consume too much network resources. To optimize the user experience and limit network traffic, all User Environment Manager files can be used locally and be synchronized only based on configurable network thresholds.

These network thresholds are configured through settings in the Network Detection category. You can define a threshold based on network bandwidth, or based on network latency. It is also possible to combine the two. Synchronization occurs only when the defined thresholds are met.

Table 1. Network Detection Settings

Setting

Description

Prefer IPv6 when resolving host names

Controls the behavior when a host name resolves to both IPv4 and IPv6. If you have not configured network thresholds, you do not need to configure this setting.

DFS namespace support

Enable this setting to perform the network measurements correctly when using DFS namespaces to store User Environment Manager files. If you have not configured network thresholds, you do not need to configure this setting.

Network measurement settings

Control how network measurements are performed when network thresholds are configured. The ping cache setting controls how long network measurement results are retained, to prevent performing multiple measurements for User Environment Manager network paths that are hosted on the same server. If these settings are not configured, 3 pings are done of 2048 bytes with a timeout of 5 seconds. The default ping cache is 60 seconds.

If you have not configured network thresholds, you do not need to configure this setting.

Network threshold: Bandwidth

The administrator specifies the minimum bandwidth that must be available for synchronization to occur. You can combine this setting with the latency threshold.

Network threshold: Latency

The administrator specifies the maximum latency acceptable for synchronization to occur. You can combine this setting with the bandwidth threshold.

Force synchronization at logon

Overrides the behavior where synchronization does not occur when network thresholds do not meet the configured requirements during login.

Enable Force sync at logon to always synchronize all User Environment Manager files at login. If you want to synchronize only certain file types, also select one or more of the other options.

If you have not configured network thresholds, you do not need to configure these settings.

Force synchronization at logoff

Overrides the behavior where synchronization does not occur when network thresholds do not meet the configured requirements during logoff.

Enable Force sync at logoff to always synchronize all User Environment Manager files at logoff. If you want to synchronize only certain file types, also select one or more of the other options.

If you have not configured network thresholds, you do not need to configure these settings.

Force synchronization in resident mode

Overrides the behavior where synchronization does not occur when the network thresholds do not meet the configured requirements in resident mode.

Enable Force sync in resident mode to always synchronize all User Environment Manager files during a session. If you want to synchronize only certain file types, also select one or more of the other options.

If you have not configured network thresholds, you do not need to configure these settings.
