NetBIOS Null Sessions

Hi all,

I have just stepped into the field of Network Penetration Testing and was trying to play with the popular null 
sessions. I enabled the null sessions on a Win XP (running in VM) as below:

Local Security policy:
Network Access: Do not allow anonymous enumeration of SAM accounts: Disabled
Network Access: Do not allow anonymous enumeration of SAM accounts and shares:Disabled

HKLM\System\CurrentControlSet\Control\Lsa\RestrictAnonymous=0
HKLM\System\CurrentControlSet\Control\Lsa\RestrictAnonymousSAM=0

net use \\1.2.3.4\ipc$ "" /u:"" is a success. But when i execute "net view \\1.2.3.4" there is a "System error 5 has 
occurred.Access is denied" error message. Googling for the same hasn't turned out the expected results on how to 
correct this. Do i need to configure any additional settings in the Win XP machine to completely allow null sessions? 
Firewall is turned off by the way.

Thanks in advance

Regards
Balaji
