    I was on an internal pentest recently where I had the following curious situation and wondered if anyone had any insight as to what may have caused it.
    
    I used gnit.exe to attempt to enumerate the users shares etc on a Win2k DC via a null session.
    This only partially worked in that I got the NBTSTAT info back and the SHARE info but NOT the user or group information.
    I was able to get the userlist via RID cycling but I was curious as to why this happened.
    Other Win2K boxes on the network (non DC) gave up everything A ok.
    Now in my experience if they had RestrictAnonymous set then I would not have got the share information back !
    They were all SP2 and had SP2SRP1 installed.
    
    Any help greatly appreciated.
