Local Only Access - No Default Gateway

Hello All,

We have a new laptop with Vista installed that is really starting to
frustrate me. Vista Business keeps sporadically changing its connection type
to local only and subsequently drops access to the internet.

After doing a bit of digging I discovered; for no apparent reason; Vista
looses the Default Gateway from the IP configuration.

(The DHCP server is running on Windows 2003.)

I found and installed the below patch from Microsoft which closely describes
a similar problem however the Default Gateway still sporadically disappears
(not just when the computer is coming out of Sleep mode) with the patch
installed.
http://support.microsoft.com/default...b/933872/en-us

As a blundered workaround; running "ipconfig /renew" from escalated
privileges does restore the Default Gateway (temporarily restoring internet
connectivity) but obviously this is not a fix as I can't expect users to do
this two/three times a day (also security issues).

Has anyone come across this and successfully fixed?

Thanks,
Tarran

How long is the lease timeframe? Does this correspond to when your
workstations lose the default gateway?
