I had similiar problems here: Samba - access denied / zugriff verweigert
After reinstalling those problems where gone now suddenly since Monday I can’t access Samba by the hostname, just by the IP it’s possible. Trying to connect by hostname does not produce log entries. Other than “password / username wrong” in the windows credential window theres no other information. DNS works flawless. Every Server/Client can lookup every Server/Client by their hostnames, the server in question also.
I have not found a solution to this as my member server with Samba seems to go corrupt after 3-4 Weeks, then I have to reinstall it because suddenly problems appear where noone can help… that can’t be normal right?
Oh and sometimes, on some computers it does work by hostname. It’s not a problem with Windows Credential manager, I checked that a 100 times. I can NSLOOKUP and Ping by hostname.
I’m just looking for help to troubleshoot this problem. I already put hours of googling into this but googling those keywords hint me that it’s a DNS problem wich it is not as already wrote above.
Thanks in advance!
