I had recent done some changes in GP. So that I can use NTLM v2 on the same. But somehow the authentication to NTLM is restricted here. I had also recently upgraded to NT. In GPMC under default domain I can see options to modify the settings. I went into Security Option which is mentioned under Local Policies to change the settings. But somehow it is not responding. I got some user complain that system is locked.
