Why does detection of a slow link to a user's roaming profile not work?

We have a remote site that has a 40mb/sec link to the primary site.  A user travels to this site and logs in and his roaming profile which is at the primary site downloads.  We have set the "Slow network connection timeout for user profiles to 51000 Kbps so the link is much slower so it should create a new local profile for the user.  Is there a method to measure the link speed the way that the OS does?  If I could do this measurement I would be able to accurately make changes to my policies based on this.

Hi,

The algorythm used is documented here : How Group Policy measures link speed
 http://technet.microsoft.com/en-us/library/cc728359(v=ws.10).aspx

...the following is taken from the next page :

"For User Profiles, the Slow network connection timeout for user profiles setting is located in the Computer Configuration\Administrative Templates\System\User Profiles item. This setting allows users to ping the server and to check the performance of the file system. This is because user profiles can be stored anywhere, and the server might or might not have IP support. Therefore, the user profile first tries to ping the server. If the server does not have IP support, it falls back to measuring the performance of the file system. You must specify connection speeds in both Kbps and milliseconds when you set this policy."

Note that there are two sets of slow link detection policy settings, I wonder if you've only set the Group Policy one and not the Profile one also?

Regards,
Alastair.
