Good afternoon,

I have an environment with 4 servers samba 4 and yesterday one of them died, I
tried removing it and not found, then recreated the server with the same name
and joined him as a DC, however, he created a new uuid and sync entres servers I
stopped, I had to force a forced sync:

# samba-tool drs replicate samba02 samba01 DC=example,DC=com,DC=br
# samba-tool drs replicate samba03 samba01 DC=example,DC=com,DC=br
# samba-tool drs replicate samba04 samba01 DC=example,DC=com,DC=br

And also performed in the 4 servers:

# samba_dnsupdate --verbose --all-names
# samba-tool dbcheck
Checking 4376 objects
Checked 4376 objects (0 errors)

But still an error occurs:

Failed to bind to uuid e3514235-4b06-11d1-ab04-00c04fc2dcd2 for
ncacn_ip_tcp:192.168.0.195[1024,seal,krb5,target_hostname=092bc931-4e23-416d-bc04-218e3fc8ef62._msdcs.example.com.br,target_principal=E3514235-4B06-11D1-AB04-00C04FC2DCD2/092bc931-4e23-416d-bc04-218e3fc8ef62/example.com.br

NT_STATUS_INVALID_PARAMETER

This error is showing every second in the log, have a safe way to remove the old
domain server? As I should have proceeded to remove a dead DC Samba4 server
domain?

Samba: 4.3.3
S.O: Centos 7
Bind: 9.9.4-29


Thank you for your help!
