"Active Directory Health Check" (ADHC) tool available to public?

I’m running a domain since long time and it seems like I have some problems with the same. SO I decided to check the same using “Active Directory Health Check” tool. But I read somewhere that the ADHC tool is only available for Microsoft employees who work to scan companies networks. But what about users like us.

I thought it could be for us as well hence I just gave a try searching on Google and even found several results for the same but i’m not able to figure out whether it is cracked or genuine. Can anyone please put some lights on the same ?

What do you think why the tool is not a free download and MS support people will come to you for the check? Even if you find one for you reliable source for the ADHC, you have no idea what's going on in your domain with just running it.

Some tools are designed to be used from real experts. And that will be the reason that it is NOT a free download.

I guess that is combination of All tools that we are using seprately like ..
Netdiag ,Spcheck ,Nltest ,Netdom ,Netcap ,httpcfg ,Dnslint ,Dnscmd ,Dhcploc ,Dcdiag ,Browstat etc...
