Impersonation Issues. ASP.NET Webform works only on Local Machine

[Guest]

I have a problem.

I have a webform, which uses impersonation. My iis is set to windows
integrated authentication and anonymous is disabled.

My webform connects to active directory and retrieves user information. This
webform works great on the local machine. But if i run it from a remote
machine, it has trouble connecting to AD. I've down some searching and it has
to do with the impersonation. I use impersonation to authenticate myself to
AD.

Even if use "Run As..." and use the administrator account in AD, to connect
remotely to the computer that is running the webform, i have the same problem.

How can i get around this? I don't want to use forms authentication. Please
help.

Hi Rocky,

The reason why this happens is likely because you are using NTLM
authentication. NTLM authentication will not work in a delegation scenario.
You'll need to use Kerberos authentication.
