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 at example.com.br,abstract_syntax=e3514235-4b06-11d1-ab04-00c04fc2dcd2/0x00000004,localaddress=192.168.0.5] 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!
