I am wondering how often and under what circumatances the DNS records change. The reason I ask is that Samba 4.1.5 running as an additional Domain Controller is unable to enter it's DNS records into our Windows Server 2000 Domain Controller. I find that samba_upgradedns can be told to put the desired DNS records into a file and I am thinking about manually entering those into the Windows 2000 DC. If the records rarely change or only change under predictable circumatances than manually entering them may be the way out of this problem. Tom Schulz Applied Dynamics Intl. schulz at adi.com
