Samba Domain Member and DNS Problems

au flag

I am trying to use my Fedora 34 workstation as a domain member but I'm having problems. First problem is that when I join the domain, I get an dns error.

net ads join -U Administrator

Enter Administrator's password:
Using short domain name -- HOME
Joined 'FSDM01' to dns domain 'home.test-server.lan'
DNS Update for fsdm01.home.test-server.lan failed: ERROR_DNS_UPDATE_FAILED
DNS update failed: NT_STATUS_UNSUCCESSFUL

I have created similar domain members in Debian and both of them work just fine. The DC is also Debian.

DC01 (10.0.0.19) = Debian Domain Controller
DM01 (10.0.0.14) = Debian Domain Member
DM02 (10.0.0.16) = Debian Domain Member
FSDM01 (10.0.0.17) = Fedora Domain Member
realm = home.test-server.lan

I can ping hostname from and between all Debian hosts. I can ping all Debian hostnames from Fedora. I cannot ping Fedora hostname from any of the Debian hosts.

Check the logs on the DNS server to see why it fails, maybe the name is duplicated, or the fqdn is invalid.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
