Hello we have an Enterprise 450 with Solaris 2.6 and mounted NFS-shares from an Sparc 20 (Solaris 2.6 too). On the Enterprise we run Samba 2.0.5a as PDC and export the mounted Shares with Samba to our WIN NT 4.0 Servicepack 3 Clients. Our problem is, that we can not set locking = yes, because then the Windowsclients can not open each files correctly. On our Sparc 20 we run a Samba 2.0.5a too without NFS-Shares and there we had no problem !!! I think the locking from the NFS will not work with Samba locking. Can it be true ? bye Julien Boppert
