DOCUMENT:Q154985 [winnt] TITLE: DNS Registry Key Not Updated When Changing Zone Type PRODUCT: Microsoft Windows NT PROD/VER:4.00 OPER/SYS:WINDOWS KEYWORDS:kbbug4.00 kbnetwork NTSrv nttcp -------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 -------------------------------------------------------------------------- SYMPTOMS ======== If you create a secondary zone and then change that zone to primary, the registry is not updated to reflect the change. The next time you restart the DNS server, you receive an error message stating that the primary DNS address is missing. In this instance the DNS server does not start. Also, the Cache.dns file may be overwritten with a blank file, causing you to lose name resolution outside your zone of authority. RESOLUTION ========== The Microsoft DNS Server has been modified to correctly write back the Zone Type key to reflect the correct role of the zone. Obtain the following fix, or wait for the next Windows NT service pack. This hotfix has been posted to the following Internet location: ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/spa/NT40/ hotfixes-postSP3/dns-fix STATUS ====== Microsoft has confirmed this to be a problem in Windows NT version 4.0. A supported fix is now available, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix.
