Giving Vista & Win7 the ability to access Xserve

I had the need the other day to make a desktop running Windows XP connect to an Apple Server for a user.  I setup a user on the OSX Server and then tried to connect to this machine from my Laptop to make sure that the account was working before I went over and tried to show the user and looked silly when it didn’t work. I found that my Laptop running Windows 7 would not work. Okay so off to Google and see what I can find. It appears that Vista & Win7 both have a different set of rights that stop the ability to set a Mapped drive to the Apple Server, LAN Manager Authentication:  Vista & Win7 defaults to “Send NTLMv2 response only”.

Here is what is needed to make it work:

Run secpol.msc

Go to: Local Policies –> Security Options

Find “Network Security: LAN Manager authentication level”

Change Setting from “Send NTLMv2 response only” to “Send LM & NTLM – use NTLMv2 session security if negotiated”

Needless to say, I got a connection and proved it worked, so was able to head over to the user and show them how to MAP a drive.
