This policy setting allows an administrator to define the Direct Access connection to be considered a fast network connection for the purposes of applying and updating Group Policy. When Group Policy detects the bandwidth speed of a Direct Access connection the detection can sometimes fail to provide any bandwidth speed information. If Group Policy detects a bandwidth speed Group Policy will follow the normal rules for evaluating if the Direct Access connection is a fast or slow network connection. If no bandwidth speed is detected Group Policy will default to a slow network connection. This policy setting allows the administrator the option to override the default to slow network connection and instead default to using a fast network connection in the case that no network bandwidth speed is determined. Note: When Group Policy detects a slow network connection Group Policy will only process those client side extensions configured for processing across a slow link (slow network connection). If you enable this policy when Group Policy cannot determine the bandwidth speed across Direct Access Group Policy will evaluate the network connection as a fast link and process all client side extensions. If you disable this setting or do not configure it Group Policy will evaluate the network connection as a slow link and process only those client side extensions configured to process over a slow link.
