Neverfail DNS Scripting tool cannot register NSIPaddressControl.ocx


This article applies to versions of Neverfail Heartbeat prior to V4.4

If the NSIPaddressControl.ocx cannot be registered, it could be due to a corrupted or partially-registered .ocx file. It may be necessary to unregister the control and execute the DNS Scripting tool again.

In order to remove all references to the .ocx file, use ONE of the following methods:

1. Unregister the control by running the following command from the Windows command-line:

regsvr32 /u NSIPaddressControl.ocx

2. If method 1. is not successful, then make sure that the control is not corrupted; normally the file will be 54,272 bytes (53K) in size.

3. Search through folders under the Windows installation directory (as defined by the environment variable %SYSTEMROOT%) to see if another copy of this .ocx file exists.

4. Remove all references to it from the registry. Delete the key - HKLM\SOFTWARE\Classes\CLSID\{F17D7F62-DF66-11D6-8222-00C0A8FA3691} and all its subkeys.

Attempt to run the DNS Scripting tool once more. If this fails again with the same problem it may be necessary to manually create DNS Scripts. See Knowledgebase article 362 for instructions on how to do this.
