[Samba] inconsistent DNS information, windows domain member issues..
I joined a Windows 10 Pro system to my (still experimental) domain. The windows system actually hosts DC2 as a VM, and another Windows (Server 2008 R2) at another location hosts DC1 also as a VM. The two locations are connected via a VPN, both systems run only when needed. The windows system does not directly use DC2 for DNS but instead talks to a DNS resolver that delegates the samba Domain to DC2. DC2 uses itself as nameserver. I am observing the following issues that may be related or not: * When I do a nslookup samba.domain DC2 I get the address of DC1, nslookup DC2.sambadomain DC2 fails. Nslookup DC1.samba.domain DC2 works. When I use dig @DC2 samba.domain it returns DC1 only. Dig samba.domain ANY returns ;; ANSWER SECTION: samba.domain. 3600 IN SOA dc2.samba. domain. hostmaster.samba. domain. 1 900 600 86400 3600 samba. domain. 900 IN NS dc1.samba. domain. samba. domain. 900 IN A 192.168.177.21 ;; ADDITIONAL SECTION: dc1.samba. domain. 900 IN A 192.168.177.21 Same information @DC2 or the local resolver of the network * On windows nslookup -type=ANY samba.domain. (note the .) Server: netgear.local Address: 192.168.15.2 samba.domain primary name server = dc2.samba. domain responsible mail addr = hostmaster.samba.domain serial = 1 refresh = 900 (15 mins) retry = 600 (10 mins) expire = 86400 (1 day) default TTL = 3600 (1 hour) samba. domain nameserver = dc1.samba. domain samba. domain internet address = 192.168.177.21 dc1.samba. domain internet address = 192.168.177.21 * windows nslookup -type=ANY samba.domain (without .) looks for samba.domain.domain. Is this OK or does it point to a problematic search configuration? * When I use the DNS mmc snap-in I can see a host record for dc2. I can also see a host record for the windows system reflecting the IP address before the system moved to the other location. I tried to update that, but got an error message (translated from German) like the database of the local security authority is internally inconsistent. The snap-in is ultra slow via VPN, but what makes me more nervous are the to me inconsistent views on the DNS nslookup showing DC2, mmc showing DC1 as the NS. * In windows management console, only some of the domain users&principals are shown with the name domain\identity, most of them are shown S-xxx. With the one use shown domain\user I can logon to the windows system however (likely with cached credentials, but don´t dare to change them to confirm) * When I try to modify folder permissions on the windows system, I get a message Unable to contact Active Directory to access or verify claim types * On DC2: kinit Administrator returns kinit: Cannot contact any KDC for realm samba.domain while getting initial credentials. This one was easy to fix by adding the domain to /etc/krb5.conf. I am putting this in as I changed configuration at this point.. * In an attempt to get Samba return DC2 as a nameserver I tried samba-tool dns add dc2 samba.domain @ NS dc2.samba.domain. Password for [Administrator at SAMBA.DOMAIN]: ERROR(runtime): uncaught exception - (-1073741643, '{Device Timeout} The specified I/O operation on %hs was not completed before the time-out period expired.')

It is shown in the DNS mmc snap-in (at least now). Restarting bind did not help. * Following https://wiki.samba.org/index.php/Check_and_fix_DNS_entries_on_DC_joins I tried root at dc2:/etc/bind# samba-tool dns add dc1 samba.domain DC2 A 192.168.15.22 -UAdministrator Password for [SAMBA\Administrator]: ERROR: Record already exists root at dc2:/etc/bind# samba-tool dns add dc2 samba.domain DC2 A 192.168.15.22 -UAdministrator Password for [SAMBA\Administrator]: ERROR: Record already exists root at dc2:/etc/bind# host -t A DC2.samba.domain Host DC2.samba.lindenberg.one not found: 3(NXDOMAIN) How should I proceed there? I don´t know how to fix the inconsistent DNS entries and get windows to work. Please advise. Thanks, Joachim

Your DCs really need to be running at all times, so that replication can work properly, also each DC should use the other for their DNS server, anything unknown to the DNS servers on the DCs should be forwarded to an external DNS that does know or can find out. Can you please post /etc/resolv.conf, /etc/hosts and /etc/krb5.conf from each DC, can you also post the smb.conf file from each DC. Rowland

Or why? Imho the point of redundancy is that you can tolerate failure. In fact I would like to run this on two bananas but haven´t found a usable distribution so far that offers recent versions of Samba (and supports encryption at least of the relevant data). Running the windows hosts all the time is not an option due to noise, energy consumption, etc. The point of whether the DC should use the respective other DC for DNS is obviously debated here. The DCs do have an upstream forwarder configured in bind.> > Can you please post /etc/resolv.conf, /etc/hosts and /etc/krb5.conf from > each DC, can you also post the smb.conf file from each DC. >joachim at dc1:~$ cat /etc/resolv.conf # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) # DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver 192.168.177.21 search samba.domain joachim at dc1:~$ cat /etc/hosts 127.0.0.1 localhost 192.168.177.21 dc1 dc1.samba.domain 192.168.15.22 dc2 dc2.samba.domain # The following lines are desirable for IPv6 capable hosts #::1 localhost ip6-localhost ip6-loopback #ff02::1 ip6-allnodes #ff02::2 ip6-allrouters joachim at dc1:~$ cat /etc/krb5.conf [libdefaults] default_realm = SAMBA.DOMAIN # The following krb5.conf variables are only for MIT Kerberos. krb4_config = /etc/krb.conf krb4_realms = /etc/krb.realms kdc_timesync = 1 ccache_type = 4 forwardable = true proxiable = true # The following encryption type specification will be used by MIT Kerberos # if uncommented.
