Vista VPN causes local network shares to disconnect

[t_jahns]

Has anyone else come across this yet? When I connect to a Win2003
server across the public internet via a Vista PPTP VPN client, after
several hours (or days) of leaving the connection active, connectivity
to my network shares (on a local Win2003 server) is lost. This
doesn't happen with the Windows XP VPN client in the same environment.

Is the server also DC? The VPN may create a virtual multihomed server so that the server have a name resolution. These search results may help,

Yes, both the remote and local servers are DCs (they're WinSBS's), but
I fail to see how that has anything to do with it. The problem occurs
with Vista but not with other XP clients (both are in the same
environment on the client's local domain). In fact if I boot up one
of my desktops with XP, the problem does not occur but if I boot the
*same* desktop computer up with Vista (via a 2nd HDD), the problem
does occur.

Is the windows 2003 server or SBS? Do you have an internal DNS? If yes, check the DNS record. Do you have the DC registers two A records?

Both local and remote servers are Windows 2003 SBS SP1. Both have an
internal DNS. There was only one A record for the Vista machine in
the local server's DNS. Note that this problem also occured with
Vista RC1. It's the reason I gave up using it.
