Offline Folders (Slow Link Detection Not Working)

Archived from groups: microsoft.public.windowsxp.work_remotely (More info?)

Have configured folder redirection for the users My Documents to
redirect to serv er and have available offline. The problem is that
even in the office on 100 Mbs switch they go offline every 15 minutes
or so. If you reconnect, you are dropped again shortly.

Group Policy of Computer Configuration of "Configure Slow Link Speed"
is set for 640, so anything better than a modem should stay online.
This started happening when the registry key

HKLM\Software\Microsoft\Windows\CurrentVersion\NetCache\GoOfflineOnSlowLink

was set to 1. Before this, the files would be online anytime there was
any connection to the server.

I've seen other posts on this issue, but no solutions....
