Windows 7 RC x64 WHS Password Conflict

When you live on the bleeding edge of technology, you are bound to find a bug now and again.  Users of the 64 bit version of the Windows 7 Release Candidate (Build 7100) have been reporting a problem connecting their machine to their Windows Home Server.  The connector software installs correctly (usually) but then the client alerts you that your Win7 machine and WHS passwords are not the same (even though they are).  When trying to enter the passwords in the prompt to fix the problem, the WHS password is not accepted (even though it is typed correctly).

Thankfully, Dan Parkinson posted a solution in the Windows Home Server Software Forums that works like a charm.  I can’t say I understand why it works, but it does.  Let’s hope this is corrected in the release version of Win7 to avoid confusion amongst WHS users.

Here is the solution posted by Dan:

Run secpol.msc
Drill down through Local Policies | Security Options.
Find Network Security: LAN Manager authentication level.
Set this Send NTLM response only (It is blank by default in the x64 RC)

Reboot the Win7 machine and you should be in business.  (Good work Dan!)
