[Samba] Failed to bind to uuid (GUID)._msdcs.DOMAIN NT_STATUS_NO_LOGON_SERVERS & IRPC callback failed for DsReplicaSync - NT_STATUS_IO_TIMEOUT

[Fernando Rodriguez]

Hello everyone.

After all the problems I had demoting my DC and managed it to work
again, it was working for only a week.

Now i am getting this messages on the log:

[2014/07/22 16:13:11.745783, 0]

for the last two days.

The funny thing is that it still knwos who is the owner of the roles:
root@hoorn:/home/newhang# samba-tool fsmo show
InfrastructureMasterRole owner: CN=NTDS
Settings,CN=VOLENDAM,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=solid-optics,DC=local
RidAllocationMasterRole owner: CN=NTDS
Settings,CN=VOLENDAM,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=solid-optics,DC=local
PdcEmulationMasterRole owner: CN=NTDS
Settings,CN=VOLENDAM,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=solid-optics,DC=local
DomainNamingMasterRole owner: CN=NTDS
Settings,CN=VOLENDAM,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=solid-optics,DC=local
SchemaMasterRole owner: CN=NTDS
Settings,CN=VOLENDAM,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=solid-optics,DC=local
root@hoorn:/home/newhang#


He still founds volendam

root@hoorn:/home/newhang# ping volendam
PING volendam.solid-optics.local (192.168.10.42) 56(84) bytes of data.
64 bytes from 192.168.10.42: icmp_req=1 ttl=64 time=0.192 ms

^C64 bytes from 192.168.10.42: icmp_req=4 ttl=64 time=0.295

but not the domain
root@hoorn:/home/newhang# ping solid-optics.local
ping: unknown host solid-optics.local
root@hoorn:/home/newhang#

Any idea?

Thank you everyone for your help and time.
Fernando

In addition to this, when I issue the command kinit
admini...@SOLID-OTPICS.LOCAL it prompts me this:

root@hoorn:/home/newhang# kinit admini...@SOLID-OPTICS.LOCAL
kinit: Cannot contact any KDC for realm 'SOLID-OPTICS.LOCAL' while
getting initial credentials
root@hoorn:/home/newhang#

Thank you

Did you edit /etc/krb5.conf on PDC
[libdefaults]
dns_lookup_realm = true
dns_lookup_kdc = true
default_realm = SOLID-OTPICS.LOCAL

And added FQDN in /etc/hosts

I fallowed https://wiki.samba.org/index.php/Join_a_domain_as_a_DC and replication and Kerberos works great on both PDC and SDC.

Hello,

Yes I did. The configuration is that and I follow the wiki.

The DC was working and was replicating. But it stops. The message
started on the 22. Before everything was working fine.

Did anyone meet this situation?

Thank you.
