Hmmmm. I just noticed a new bit of new information while running some 
tests. When "Append these DNS suffixes (in order):" is selected under 
the Advanced TCP/IP Settings DNS Tab for any adapter, it becomes a 
global setting that supersedes all adapter specific default domains.

I think this means we may be having more than one issue ...

1) The tunnel specific DNS server is being used, but only fully 
qualified domain names can be resolved. This is due to the "Append these 
DNS suffixes" being specified as described above.

2) The tunnel specific DNS server is not being used *at all* to resolve 
names for several minutes after connecting. This can be temporarily 
worked around by using the "net stop/start dnscache" command.

Can the folks that are having DNS problems please let me know which 
category they fall under?

Thanks,

-Matthew
