Force Offline Files fix not working

I work primarily offsite and connect to the company LAN via VPN. I'm using
Win2K Server as my desktop OS. I have a folder that resides on one of the
company servers that I'd like to setup to utilize Offline Files. The catch
is, I would like the folder to function in off-line mode even when my
network connection is active. That way I can synchronize manually at my
convenience, say at 2:00am when I'm asleep, but the rest of the time I can
work on local versions of files. Some of the files are very big and due to
other Win2K browsing issues, just navigating a couple folders on the server
over the VPN connection takes *forever*.

The ability to handle this scenario has apparently been requested enough
that MS issued a hotfix and a couple KB acticles explaining how to make this
happen. According to this KB

Configure Slow Link Speed Group Policy does not force offline files to
offline mode when a slow link is detected
http://support.microsoft.com/default.aspx?scid=kb;en-us;811525

in order for this to work for Win2k, I need Update Rollup 1 for Windows 2000
SP4 and a Hotfix. I then have to make a reg edit and adjust a group policy
setting. I've done all of this but I do not get the expected behavior. I
have also set the

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\NetCache\SlowLi
nkSpeed

key but that has not made a difference. The latest values I've used for the
settings mentioned above are as follows:

Configure Slow Link Speed Group Policy setting = 120000
SlowLinkSpeed = 1200000

I have two separate values because the documentation specifies that each one
is calculated differently. For the group policy setting it's calculated by a
formula explained here:

How a Slow Link Is Detected for Processing User Profiles and Group Policy
http://support.microsoft.com/?id=227260

For the registry entry it's calculated as explained here:

Transition of Offline Files to Online Only Occurs Over Fast Link
http://support.microsoft.com/?kbid=263097

Either way I wanted to set it so that it was greater than 100Mb. Apparently,
Win2K (pre-hotfix) used the reported speed of NIC to determine if the link
was to be considered slow, as opposed to the actual transfer speed of the
connection. Just in case the NIC speed was being used, I wanted to set the
threshold higher than 100Mb to assure that even a 100Mb connection would be
considered slow. However that has not made a difference.

Here's a very informative article that explains in detail how this should
work.

However, unfortunatley, when I attempt to access the network folder, instead
of it switching to offline mode and opening the local offline folder,
Windows opens the actual online, network based folder.

Are there any other tweaks to try that aren't mentioned in any of those
articles to try? Has anyone got this to work on Win2K even?

Also the settings will not take affect until you go offline and then come back on you can run this command Csccmd /disconnect  to do that.  Here is a great link discussing the process the first page is the microsoft page you posted but scroll down and there are more really informative microsoft articles.

Hi,

i suppose you are using win2k prof instead of win2k server as pc OS?  When you connect through vpn, is there some login script running that maps networkdrives automatically or is the OS started offline first and is a connection than made by yourself through VPN to the company LAN?

\BR,
Svego.

Yes, see "Configure Slow Link Speed Group Policy setting = 120000" in orig post.

That's what I'm trying to avoid. Look at

http://www.itproffs.se/forumv2/tm.aspx?m=39053

and read through the following headings:
Server Connection Default Slowlink detection:
New Slowlink behavior:
What is the feature?
Why we did this?

The "Why we did this?" part explains my scenario.

That particular article seems to focus on WinXP, however it references MS KB article 811525  "Configure Slow Link Speed Group Policy Does Not Force Offline Files" which specifically states that the same "new" behavior is available for Win2K.


>i suppose you are using win2k prof instead of win2k server as pc OS?

No, see orig post. I'm using Win2K Server as my desktop OS. And, no, no login script is running. I startup as a stand alone machine. My desktop PC is not part of the comapny domain. The VPN connection is a full-time link between two Watchguard routers.

Well, it looks this is working after all. Here's what threw me...

When I was attempting to access the network share by double clicking a saved favorite in My Network Places, I was being presented with an autentication dialog box. It was apparent that Windows was accessing the actual server because there was a long lag (about 30 sec) before poping the auth dialog up.

As such I just assumed that Windows was ignoring my desire to work offline and was connecting the network share anyway. Turns out that if I proceeded to athenticate, at that point Offile Files would kick in and the local folder would open.

So, apparently Windows must still autenticate to the actual server even though it ends up switching to offline mode afterwards. I assume that if I had my desktop PC setup as a domain member then the authentication would happen at login and the switch to offline mode would happen right away when I accessed a network share, thus not giving the illusion that it was accessing the actual network share.

So the bottom line is that it does work after all.
