Hi

I've developed a remoting application that uses a TCP channel with a Binary
formatter. The server side is a Windows Service that is on the same server
as the database.
When I deploy the server part, I usually create a user account on the server
that the clients use to connect with (the clients aren't always on a
domain).
Now this application works on my computer (server and client installed on
same pc), it works on all our customer's networks but for some reason I
can't get it to work on my partner's new computer that is set up with
Windows XP SP2. The Windows Service and SQL Server 2000 is loaded on his
computer and the client components which basically connects to the service
on the same computer. I've tried connecting by specifying the location's IP
address, localhost and the computer's name. I tried connecting via the user
account that I created. tried using the username that I was logged on with,
Administrator and even tried leaving it blank.
Is there some setting that can cause this? The "Allow this computer to be
accessed from network" policy has the users linked to it.

Oh yes... the error that I get is "A remote side security requirement was
not fulfilled during authentication. Try increasing the ProtectionLevel
and/or ImpersonationLevel."

I got the same problem... i'm trying to solve it playing with
TokenImpersonationLevel and stuff like that but still nothing... my SqlServerExpress is on a XP sp2 while the client is a Win2000... the firewall is opened, when i set the channel not secure it works, but SqlServer denies access, while with channel secured the it does'nt work....

Have you tried setting typeFilterLevel="Full"?

Hi

I don't think the problem is in the code since this is an isolated case.
The application is currently running on approx. 5 networks without any
problems.
In this case, it is a laptop that has just been installed with Windows XP SP
2 with all the latest updates and fixes.
I've loading the server (hosted by a Windows Service) and client components
on the same computer and attempt to connect to the server components. The
computer isn't connected to a network so I also tried connecting from
another computer to the server components on that computer via a VPN but the
same problem. I can however connect the client components on that computer
to another server and that works. So I guess the problem is somewhere
related to the server components or Windows Service.

Any suggestions now?

Hi

Found the solution.

Under folder options, "Simple File Sharing" should not be enabled.

Knew it was a setting somewhere on Windows.
