[Lug-nuts] Re: DNS problem

Hi Folks, O.M.G.! I have spent all afternoon trying to diagnose a DNS problem that presents like corruption but I can't find any trace, beyond the failure that I think is the result. This is a Windows Server problem... I have a domain name for my NAS -- "\\NAS0.TCLC.org = 10.1.1.80", and all evaluations show me that translation. I can ping it; I can nslookup; I can run the DNS management application. My linux machines can "mount //NAS0.TCLC.ORG/d0 /net/nas0/d0 ..." All work exactly as you'd expect. Then I try to view the share with the Windows File Explorer -- "Windows can't find the DNS name"!! In that case I can use the IP address directly or the alternate domain name, so it is the domain name on the windows machines that is the problem, not the disk access protocol. I also created a second domain name "\\NASX.TCLC.org = 10.1.1.80" and that one work just fine everywhere! Here I tried the command prompt: C:\Windows\system32>net use n: \\10.1.1.80\d0 The command completed successfully. C:\Windows\system32>net use n: /delete n: was deleted successfully. C:\Windows\system32>net use n: \\NASX.TCLC.org\d0 The command completed successfully. C:\Windows\system32>net use n: /delete n: was deleted successfully. C:\Windows\system32>net use n: \\NAS0.TCLC.org\d0 System error 64 has occurred. The specified network name is no longer available. Of course I have flushed all caches I can find, scavenged resources records, rebooted every element -- Windows DNS server, Windows Server 2012r2, NAS, Client, ... the toaster and the microwave! So, I have a domain name that shows zero problems in any investigation, until I try to use it for its intended purpose on the windows machines, and I have another one that is nearly identical that has no problems! Any thoughts?
