As you have chosen to go off in a different direction, rather than the described one, I cannot help you any further other than to say don't try to move the mountain to mohamed! All devices that interoperate using Samba/SMB/CIFS need to be in the LINUXMCE "domain", so move your 0910 machine into that domain rather than trying to edit LMCE's scripts. BTW, needing a "domain" is not a bug, it is the "workgroup" context that the security model requires and is normal. Some less secure systems may overlook that and assume the local context, but that is more a bug in those systems...
