DOCUMENT:Q172477 10-AUG-2001 [winnt] TITLE :DNS Manager Hangs While Displaying Zone Information PRODUCT :Microsoft Windows NT PROD/VER:WinNT:4.0 OPER/SYS: KEYWORDS:kbnetwork ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows NT Server version 4.0 ------------------------------------------------------------------------------- SYMPTOMS ======== When you view your Domain Name Service (DNS) zones with DNS Manager, it may stop responding. If you check Performance Monitor or Task Manager, then you may notice that DNS Manager is using up to 90 percent of the CPU Utilization. CAUSE ===== One or more of your zones may contain more than 65,553 records. RESOLUTION ========== There currently is no resolution for this issue. The DNS server will start and continue to function correctly, it is just DNS Manager that stops responding. If you have zones with more than 65,553 records, then you will need to edit these files using a text editor, such as Notepad.exe or Edit.com. NOTE: Remember to stop the DNS server before editing the zone files and restart the DNS server after you have saved the changes to the zone files. STATUS ====== Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
