The mailing list archives mention this as a problem, but I didn't see any specific steps given to fix it: We have Samba running on four servers - two at Samba version 1.9.18.p10 and two at 2.0.3. One of the 2.0.3 servers is on Solaris 2.7, 3/99 update. It has an smb.conf file essentially identical to that of the other 2.0.3 system, but it's impossible to add a printer on this system to NT W4 Sp3/4/5. If we do My Computer / Printers / Add Printer and browse, the printer shows up for the Solaris host, but if you put the cursor over the printer name, then under the browse we see the helpful message: Printer information Error: The handle is invalid. Double-clicking the printer gives an error pop-up saying Could not connect to the printer. The printer name is invalid. It *is* possible to net use the printer to LPT1: from a command window and print to it. Any ideas on how to tackle this one? BTW, the other 2.0.3 system runs OpenBSD 2.5. It also had this problem for several days, then the problem mysteriously vanished. Now the "printer driver" name isn't picked up. (The same driver name is picked up from our other two servers.) We've tried several permutations, but here's the latest smb.conf from the Solaris 2.7 system: [global] workgroup = MAIN netbios name = SOLAR7 name resolve order = host wins server string = Samba %v hosts allow = 192.168.47. load printers = yes log file = /var/log/log.%m max log size = 50 security = server password server = MAINPDC socket options = TCP_NODELAY interfaces = 192.168.47.75/24 local master = no wins support = no wins server = 192.168.47.1 dns proxy = no [homes] comment = Home Directories browseable = no writable = yes [printers] comment = All Printers path = /var/spool/samba browseable = no guest ok = no writable = no printable = yes printer driver = HP LaserJet 5Si/5Si MX PS
