Hello, i begin a collection of Windows beta cd, and i found a Windows Longhorn server 2008 Enterprise. I don't know if it is a real because there is no text say: "do not seal this copy".
On the top of the Cd there is a red line and there is write "Microsoft / Partner Program". on the left there is: "ot for retail or Oem distribution". On the right there is "Warning! This software is for international Business Use, Testing, and Development purposes as stated in your action Pack Subscription Agreement". behind there is the date "10/2007" and there is "Windows Server 2008 Enterprise 62-bit Beta".
Ther is a copy right: "2007 Microsoft Corporatio. All rights Reserved.
I hope it is a real beta!

(sory if there is some mistake, I don't speack english very well).

Information, after the installation of Windows, there is on the right bottom a text: "Windows Server (TM) Code Name "Longhorn" Build 6001 This copy of Windows is not genuine.

6001 is Vista's RTM, right? Might be an RTM build I guess.

So I think it is not a real version...

Actually, build 6001 is Windows Vista Service Pack 1. However, Windows Server 2008 was released around the same time as Service Pack 1 for Windows Vista. That's why Windows Server 2008 RTM has build number 6001.

If it is a RTM version it is not a real beta version?

Yeah, most of the later development of Server 2008 was done alongside Windows Vista SP1, and that's why a lot of builds around this time use the build number of 6001. For what it's worth, this build does seem to be a real beta.
However, one thing that might be useful to check (because there are many 6001 builds) is the full build number, that can be seen in regedit.exe by going to the location "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion", and looking for the "BuildLabEx" key. Can you check and see what revision of 6001 this build is?

Ah yeah, forgot about that! It is the RTM of Server 08.

Anyways, this would be a cool find, you should check the full build screen and tell us your results.

There is not file "BuildLabEx" in Windows NT\Current version.

I found a file "DefaultProctKey, it is that? There is 4 files in: "(Default)" "DigitalProductId" "DigitalProductId4" and "ProductId"

A lot of later betas of Server 2008 were build 6001. Considering the date this might be RC0. You have to look at the exact revision of the build to find out (6001.16659 is RC0 for example)

I forgot, on the CD there is a Part No. X14-07634
