How To - Connect Windows 7 to Mac OS X Server – Forget Computers Help Center

Contrary to this Apple KB article, Windows 7 can be connected to a PDC Domain running on Mac OS X Server. We have successfully connected Windows 7 machines to both a PDC and an Open Directory Master running on Mac OS X Server 10.6 Snow Leopard using the solution below (originally found at MacWindows.)

SUMMARY: tell Windows 7 to NOT encrypt communications to and from the server.

From Windows 7:

Type Secpol.msc in start button.

Expand "Local Policies" and select "Security Options."

Alternate : Type secpol.msc to get editor up then

Locate "Network Security: LAN Manager Authentication Level" in the list and double-click it.

Change the setting from "Send NTMLv2 response only" to "Send LM & NTLM -use NTLMv2 session if negotiated" Apply & OK.

Then locate "Network Security: Minimum session security for NTLM SSP Based (including secure RPC) Clients."

Change the setting from "require 128 bit" to unchecked (No Minimum).

Click Apply and OK.

CLARIFICATION:

We've received feedback from a reliable Apple source that says BINDING (or Joining) Windows 7 clients to Mac OS X Server 10.6 Snow Leopard can have long-term side-effects (i.e. problems with changing the network password) so beware and let us know what you discover!
