Thanks, Richard. The user's identity isn't an issue for me; it will always
be either Local System or Network Service. All I care about is whether the
machine itself is joined to a domain, as its credentialls would be the
ones
presented to AD. I did manage to dig up this, though:
System.DirectoryServices.ActiveDirectory.Domain.GetComputerDomain(). It
may
do the job, but I'm unsure of a couple of things:
If the computer is joined to a domain, but is running offline, the docs
say
it will throw an exception. That's fine with me, but what sort of timeout
might I expect, and is there a way to minimize that timeout?
If it becomes an issue, I can always just cache the (boolean) result. If
the
machine's domain member****p changes while the app is running (highly
unlikely), the consequences are minimal.
