Getting Vista to join an NT 4 Domain

Well, probably not too much demand for this, but I’ve still got a legacy domain to support until I can get everyone moved to the new AD.

I was able to find the info on this here:

To add Vista to the domain:

1. SRVMGR.EXE on the PDC and add the computer name of the Vista PC.

2. On Vista PC run, secpol.msc then Under Local Policies > Security Options, Change the following two settings

– Domain Member: Digitally Encrypt sign secure channel data (always) – change to disabled
– Network Security: LAN Manager authentication level – change to “Send LM and NTLM – use NTLMv2 session security if negoitated”

I was able to successfully test this in VPC.  NT4 on a 3GHz Quadcore is crazy fast.  I had an NT4 PDC with SP6 and VMA in under an hour.
