When the Domain Name Service (DNS) Admin tool is used to configure DNS for a large number of DNS zones (over 1,000), you may experience one of the following:

  • The following Dr. Watson error:

    The application, dnsadmin.exe/DNSadmin.dpg, generated an application error. It occurred on MM/DD. The exception generated was C00000005 at address XXXXXXXX (RTL destroy heap).


  • DNS Manager may hang or stop responding. When you select a zone name and then click Properties from the context menu the Properties dialog box does not open and the cursor remains an hourglass. You may also notice that the available system memory steadily decreases.

    A Performance Monitor log of your system shows that the private bytes counter, associated with the Dnsadmin.exe process, increases dramatically as available system memory dramatically decreases.


To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
