[Samba] Domain clients system hidden shares are accessable from other client systems.

[sumit sen]

Hi All,         I am running Samba 3.5.3 as a Domain Controller with openldap with Windows XP clients .  One strange problem I am facing is that whenever from a windows client system I type //<Ip of anothe system>/c$  I am able to get into the other  systems default shares without any authentication which is also a domain client.  Can any one help me with that please.
