[Samba] Weird permission problem

[Howard Miller]

Hi, 
 
When I try to do anything on my samba system a connection is made to IPC$, but this is 
mapped to a directory /root/tmp. This seems odd. To make matters worse ordinary users 
cannot access this directory, so the only user who can access the IPC$ share (ie, do 
anything at all) is the root user. 
 
What have I don wrong. I cannot find any reference to IPC$ being linked to a directory 
anywhere. 
 
Thanks
