Hello, I am having problems installing printer drivers for Samsung ML-4500 printer, so windows workstation can just fetch them from print$ share. When I run rpcclient with -d 4 i get the following error: whale:/home/samba/home# rpcclient -d 4 -Uroot%xxxx -c 'adddriver "Windows NT x86" "SSGK2:ssgk2.cnt:ssgk2.dat:ssgk2.dll:ssgk2.hlp:ssgk2.ini:ssgk2.sdd:ssgk2su.dll:ssgk2ui.dll:ssgk2um.dll' WHALE added interface ip=192.168.77.7 bcast=192.168.77.255 nmask=255.255.255.0 added interface ip=172.16.104.1 bcast=172.16.104.255 nmask=255.255.255.0 Connecting to host=WHALE Connecting to 192.168.77.7 at port 445 Serverzone is 0 Doing spnego session setup (blob length=58) got OID=1 3 6 1 4 1 311 2 2 10 got principal=NONE Got challenge flags: Got NTLMSSP neg_flags=0x60890215 NTLMSSP_NEGOTIATE_UNICODE NTLMSSP_REQUEST_TARGET NTLMSSP_NEGOTIATE_SIGN NTLMSSP_NEGOTIATE_NTLM NTLMSSP_NEGOTIATE_NTLM2 NTLMSSP_CHAL_TARGET_INFO NTLMSSP_NEGOTIATE_128 NTLMSSP_NEGOTIATE_KEY_EXCH NTLMSSP: Set final flags: Got NTLMSSP neg_flags=0x60080215 NTLMSSP_NEGOTIATE_UNICODE NTLMSSP_REQUEST_TARGET NTLMSSP_NEGOTIATE_SIGN NTLMSSP_NEGOTIATE_NTLM NTLMSSP_NEGOTIATE_NTLM2 NTLMSSP_NEGOTIATE_128 NTLMSSP_NEGOTIATE_KEY_EXCH NTLMSSP Sign/Seal - Initialising with flags: Got NTLMSSP neg_flags=0x60080215 NTLMSSP_NEGOTIATE_UNICODE NTLMSSP_REQUEST_TARGET NTLMSSP_NEGOTIATE_SIGN NTLMSSP_NEGOTIATE_NTLM NTLMSSP_NEGOTIATE_NTLM2 NTLMSSP_NEGOTIATE_128 NTLMSSP_NEGOTIATE_KEY_EXCH lsa_io_sec_qos: length c does not match size 8 result was WERR_INVALID_PARAM Does anyone know what the problem is and how to fix it?
