Question

How do I detect if my program runs in an Active Directory environment?

I'm using C# and .Net 2.0

Answer 1

Try getting Environment.UserDomainName and comparing it to Environment.MachineName. If the two are the same then it's likely that the user does not have a domain. If they are not the same then the user is logged into a domain which must have a directory server.

Answer 2

This code will check if the Computer itself is a member of a domain

using System.DirectoryServices.ActiveDirectory;


bool isDomain = false;

try
{
    Domain.GetComputerDomain();
    isDomain = true;
}
catch (ActiveDirectoryObjectNotFoundException)
{
}

However the computer can be in a domain, but the currently logged in user may be a local user account. If you want to check for this use the Domain.GetCurrentDomain() function
