Cannot use Windows Authentification over VPN

Hi,

I'm trying to connect to my SQL Server 2000 over a VPN IPsec. The VPN
connects succesfully, I can browse with the Windows Explorer the shared
folders of my SQL Server.
When I ping the server the servername is resolved, and when I use ping
-a also resolve the dns.

My problem is the connection to the SQL Server with Windows
Authentification, the following error is throwed:

"Unable to connecto to server...

ODBC: Msg 0, Level 16, State 1
[Microsoft][ODBC SQL Server Dirver] Cannot generate SSPI context"

But when I use SQL Authentication works fine.

Can anyone help me please?

Thanks in advance,
David S

Hi guys...

Doing some test I think I know where is the problem.

As I describe in the past post, I'm using a Client VPN aplication to
communicate a mobile user to the main app in the hq. The things is that the
mobile user log in to his domain account when the VPN is not yet established,
so the DC doesn’t finds out when the user log in.

Once the VPN is up a running the user can access the different shared
folders. But when I try to connect to my app with SQL Server and Windows
Authentication, the app throws the following error: “Cannot generate SSPI
context”.

Is there any way to re-login once you have log onto your account or
just to establish a connection with the DC?

Thanks for your help,

David S
