Just for sake of curiosity: Is that possible ? I'd like to support XP Pro *only* and to ban any other Windows OS (no 2000 server or 2003 server machines in here). Samba works in domain mode with Ldap backend. Cheers, -- Michal Kurowski perl -e '$_=q#: 13_2: 12/o{>: 8_4) (_4: 6/2^-2; 3;-2^\2: 5/7\_/\7: 12m m::#; y#:#\n#;s#(\D)(\d+)#$1x$2#ge;print'
