Hi all, In my win2k ADS server(mixed mode), I have set the LAN Manager authentication level to Send NTLMv2 response only\refuse LM & NTLM. In the registry, i also set HKLM\System\CurrentControlSet\Control\Lsa|lmcompatibilitylevel --> level 5 (accepts only NTLMv2). Similarly, i also set HKLM\System\CurrentControlSet\Control\Lsa\MSV1_0\NtlmMinClientSec --> 0x00080000(NTLMv2 Session security) HKLM\System\CurrentControlSet\Control\Lsa\MSV1_0\NtlmMinServerSec --> 0x00080000(NTLMv2 Session security) In my smb.conf, I added client NTLMv2 auth = yes lanman auth = no ntlm auth = no I have waited for about 5 minutes just to be sure that all setting may take effect. After 5 min, I join the domain thru "net rpc join -w domainname". I was able to join and there seems to have no problem. I executed winbindd wbinfo -t, wbinfo -u, wbinfo -g ---everything is ok ntlm_auth --username --> OK successfull getent passwd --ok Now I reboot my ADS server, (I have also deleted my samba computer name in the Active Directory users and computers) After reboot, I join again but this time it fails. The message is "Unable to join domain 2K-ADS" May someone please help me on how to deal with this... the result for net rpc join -w domainname -d 3 is listed below. I also attached my smb.conf.
