ElGranDoofus Posted April 7, 2010 Share Posted April 7, 2010 In a small shop with an NT4 PDC, I've been trying to connect some new machines. The clients are Windows 7 professional, 64-bit. Trying to map a network drive from the PDC fails (invalid username/password), so does trying to join the domain. I've tried user-pass, user/domain-pass, etc., no luck.Finally, I went over to the NT4 server, and took a look in the event log. No reports of any failed logins at all. Now I'm confused.I made sure that the Win7 clients have the client for Microsoft networks, and that they have file sharing enabled. Just for fun, I even tried with their firewalls turned off. No luck.Is there something I'm missing here? Link to comment Share on other sites More sharing options...
cluberti Posted April 7, 2010 Share Posted April 7, 2010 Is there something I'm missing here?Yeah, something quite obvious too:http://support.microsoft.com/kb/940268Windows 7 and Windows Server 2008 R2-based computers cannot be joined to a Windows NT 4.0 SP6A domain. There are no workarounds for this behavior.http://technet.micro...706(WS.10).aspxApplies To: Windows 7Windows® 7and Windows Server® 2008 R2computers cannot be joined to a Windows°NT® Server°4.0 SP6A domain.Additional informationThere are no workarounds for this behavior. This is by design as Windows°NT Server°4.0 is no longer supported. Link to comment Share on other sites More sharing options...
ElGranDoofus Posted April 7, 2010 Author Share Posted April 7, 2010 Well, I guess that's what I was missing. Thank you! Link to comment Share on other sites More sharing options...
cluberti Posted April 7, 2010 Share Posted April 7, 2010 You could do this with an XPMode VM, but you aren't going to get access to (or join up with) anything on that NT4 domain. Link to comment Share on other sites More sharing options...
MrJinje Posted April 7, 2010 Share Posted April 7, 2010 (edited) Well, I guess that's what I was missing. Thank you!Rumor is some people are joining older domains using XP Mode, from Windows 7. With app integration, I imagine it would be seamless.EDIT: Looks like Cluberti's beat me to it.... Edited April 7, 2010 by MrJinje Link to comment Share on other sites More sharing options...
awergh Posted April 8, 2010 Share Posted April 8, 2010 Perhaps you can try this because obviously its possible.http://www.msfn.org/board/solved-join-windows-machine-domain-t128488.html Link to comment Share on other sites More sharing options...
cluberti Posted April 8, 2010 Share Posted April 8, 2010 It is, but it puts all of your NTLM data in clear text out on the wire - not that the NTLM hashing in NT4 is great, but it's something. Cool that someone figured it out, not cool what it takes to make it happen . Link to comment Share on other sites More sharing options...
MrJinje Posted April 8, 2010 Share Posted April 8, 2010 Good catch awergh, forgot all about nitro's method Here is a quick re-cap. (in case that link ever stops working in the future )open secpol.msc and change the highlighted setting You need to "Enable" that setting. (it should be disabled by default) Link to comment Share on other sites More sharing options...
