Someone

I Have Joined my samba to AD everything was successfully done, Now when i try to access a share from ADS Domain Profile i can do it by browsing through My Network Place> My ADS Domain > Samba Domain,without any user n pass authentication box being popped up, When i try the same through Run command (by entering my samba machine name) it asks for username n pass and when i enter a valid user n pass, it is not authenticating that user. Can u please tell me why is this happening? Here is my winbind log >> http://pastebin.ca/726764 and my smb.conf >> http://pastebin.ca/726761 and my smbd.log >> http://pastebin.ca/726762
