Vista - Make offline files always stay in a "Manual offline mode"

Hi all,

Is there any hack to force offline files to always stay in a "Manual offline
mode" (the definition of the said mode is here:
http://technet2.microsoft.com/Window...spx?mfr=true)?
Here is what I am trying to accomplish. My documents and even my favorites
and system settings are stored on the DFS share behind the firewall. I
access them 99% of the time through a VPN. This can be from any place and
most of the time connection, especially through VPN, is slow. I don't want
the system to check for me if my connection to the server is slow or fast. I
want always access my fast offline local cache and sync on a schedule or
when I need it.

So far I have tried the following: Defined the slow-link mode in a group
policy as \\share\*", "Throughput=9999999999". Most of the time it works. I
work with the local cache and have a "Work Online" button available.
Although it still takes a minute or two for the system to test the link
speed and go to the Manual offline mode. I can live with that, however I
would prefer to set a setting somewhere to liberate the system from doing
such unnecessary work.

But once in a while something goes wrong and system goes right into a "Auto
offline mode" (definition is in the same link above) and I can't sync, can't
go online... This only happens with this \\share\* resource and not with
another resource (let's say \\share1\*) that does not have slow link policy
defined. So I suspect that there is some relationship between a "Throughput"
value in a policy setting and how the system determines whether there is a
link problem...

What is also interesting - while it is virtually impossible to get such
speed (9999999999 bps) through a VPN connection - once in a while system
switches to "Online mode"... Meaning that all suddenly my 1 mb word document
takes several minutes to save. And I have to close a document, open the
share, wait intil it reads all the sutff from a network, and then push an
"Work Offline" button to see a message happily telling me that I need to
close all my documents to proceed or otherwise I would loose all of my
work...

Is there any solution?... Please help

Thanks a lot.
