Vista + VPN + SQL server + Windows Authentication mode

Hello everyone!

I have a question regarding connection to SQL server using Management Studio
Express on a computer with Vista Business while using a VPN connection to
the network.

With Windows XP (my computer is not in company domain) after connecting
through VPN to my office domain (with a username which is a member of
domain admins group) I could connect to SQL server (2000 and 2005) using
Windows Authentication. After installing Vista that is no longer possible. I
get a message - Login failed for user '(null)'. Reason: Not associated with
a trusted SQL Server connection. (Microsoft SQL Server, Error: 18452)
BTW. In the Options of the VPN connection - "Include Windows logon domain"
is checked.
Connection with a SQL server Authentication mode works without any problems.
Any ideas?

Best Regards

Similar problems here also, getting error 734 PPP link control protocol
disconnect. No change except for Vista Untimate. Can still use an Xp system
with no problems behind same firewall.

Same problems here. Have any solutions or suggestions appeared?

I have been told that the problem is related to authentication and
that the solution is to authenticate against the domain (not the VPN
firewall) and to then route all traffic through the server used for
authentication - makes little sense to me but hey when it gets to bits
and bobs it gets all too technical for a simple mind. Why on earth
woudl I have expected Vista Business to just work like XP - duh!!! No
wonder most of our top guys are uninstalling Vista and opting for
XP.....any idea when they port mac to pc?

And this is exactly the way I do it. I authenticate against a domain
server.
I have access to all domain shares with the correct access rights but not
the SQL server!!!

Really nobody knows what the problem might be??
