I am at a loss. I have two SUNs and 10 PCs (W95) on our network. One SUN box runs Solaris 1.1.1, it has four serial printers (old printers never die they just...) running from a serial extension card. Users validate when the come to their PC so they can access the printers and the disks on the SUNs. The second SUN runs 2.5.1 and I wanted to move the printer activity there with time. I created two printers under Solaris running from the serial ports. I can attach a serial printer and print from the 2.5.1 box and print to the 2.5.1 printer from the 1.1.1 box and vice versa BUT none of the PCs sees printers attached to the 2.5.1 box. I run Samba 1.9.18p2 on both machines and use identical smb.conf files. On 1.1.1 the printers work fine and on 2.5.1 I cannot access them via samba although I can using solaris commands. The 2.5.1 machine is the domain master and the problem is unaffected by turning off the 1.1.1 machine. I wondered if it was some serial thing and recently installed a HP lasetjet on the network through an ethernet card. I added it to the 2.5.1 machine and it all works fine but again cannot be accessed through Samba (although it works fine from a W95 machine running JetAdmin etc). Has anyone had this problem with 2.5.1? It should be said that I have tried perhaps 4 different Samba versions (last one 1.9.17p1) and the problem is identical? Any suggestions? Peter Goadsby
