samba - Oct 1998 - Typing in passwords on NT clients

Hi All,
     
     We are running Samba on a Sun Ultra 1 running Solaris 2.6.  When we 
     connect to the Samba server with an NT client, and map the Samba 
     drives, we have to type in the password over and over for each share 
     we map.  This would be ok if we weren't mapping ten or so shares.  Can 
     this be fixed?
     
     Thanks,
