Couple years ago we performed a Domain Name Rename following the guide from MS and for the most part it went smooth.
Today I noticed a few issues and while not catastrophic it is a pain in my rear.
First the reason we renamed was because we had a _ in our DNS and well he had some new Macbook's that didn't like joining our domain because of it. The other issue as to why we renamed is Exchanges OWA. We found it easier to tell people to enter their email address as their username because a lot of them would confuse \ with /.... etc.
So we renamed our domain to xxx.yyy.com
During the rename process it also required the netbios name. Well at the time we simply made it the initials (abcd) of the company instead of xxx. As you can see it does not resemble the domain name at all.
We never used WINS and netbios seemed to work as you could always pull names from netbios (ie going to \\servername always worked and still works). Few days ago I found out from a a post on MS's website that WINS will not work due to the netbios name not being xxx for whatever reason.
Issue we have is since then we received copiers that can store scans on servers.... well during setup they can see everything in the folders on the various file servers however when it comes time to scan it can't reach the server. When you look at the logs it shows it tried contacting server.abcd.local which doesn't exist. abcd\server does though.
When joining a machine to the domain we have to put the full domain name as the netbios name does not seem to work. When the machine reboots after joining the domain the netbios name shows in the dropdown like it should.
Other issues are SQL related but it is related to this for the same reason... software can't seem to connect to the SQL server.
So is there a workaround, fix, or anything or would be easier to rename the domain again and make xxx our netbios name?
Is there another way to change the netbios name of an AD domain?
