Hello Tim,
Thanks for your response and thanks for your experience sharing!
Good to know we find the root cause. Actually, Windows contains the "Media
Sensing" feature. You may use this feature on a Windows-based computer
using Transmission Control Protocol/Internet Protocol (TCP/IP) to detect
whether your network media is in a "link state." A "link state" is defined
as the physical media connecting or inserting itself on the network. For
example, assuming a 10bt or 100bt physical media, Ethernet network adapters
and hubs typically have a "link" light to indicate the current connection
status. This is the same condition in which Windows can detect a link.
Whenever Windows detects a "down" state on the media, it removes the bound
protocols from that adapter until it is detected as "up" again. There may
be situations where you may not want your network adapter to detect this
state, and you can configure this by editing the registry.
For current situation, if you would like to disable "Media Sensing"
feature, the following article may be helpful:

Hope that helps!
Thanks & Regards,

| It would seem that as soon as the network connection (cable or wireless)

| It would appear that it is caused by the Media sense detection system for
| the NIC. Maybe my only workaround is to tell the users that they must
| connect to our VPN and manually synchronise.
