Hello,

I was wondering how I would go about writing some code that would be able to
authenticate a user atainst a Domain Controller on an old NT4 domain.

The call would be coming from a server or client machine that isn't
necessarily even part of the old NT4 domain.

Is this possible? If so, does anybody have any resources, links, sample
code? Are there any classes included in the .NET framework that would help
facilitate this?


thanks very much,
-ZD

ZD,

I think that the easiest way to do this would be to call the LogonUser
API function. Assuming that the machine making the call is part of that
domain you want to authenticate against, it shouldn't be a problem.

Hope this helps.

Hi Nicholas,

Thaks for your reply.

Unfortunately, as I mentioned in my post, the machine that I'll be making
the call from wont necessarily be part of the old NT domain. This is why I
was wondering if this sort of thing would be possible and how I would go
about doing it...

thanks

ZD,

Sorry, I didn't read that correctly. In this case, you will have to
have something on that domain which can take authentication request. A web
service comes to mind...

Hi Nicholas,

Thanks again for your reply.

I did some searching and according to this article, the author says that the
"lpszDomain" parameter in the LogonUser API call can be used to specify the
name of a workstation/member server on the network for authentication
purposes.

Is this correct? Or does that only work if the caller is still part of the
domain?

Thanks

ZD,

Forgive me for this whole thread, my brain just isn't working right.
Yes, you can use the lpszDomain parameter to specify the domain. My
apologies.

Don't be to hard on yourself, Nicholas. This sort of thing is bound to
happen every 11,000 posts or so.

Nicholas,

No worries! Thank's for taking the time to respond. I appreciate it very
much.

Thanks again.
