Update Your DNS Software (Windows)

If you have a Windows dedicated server running Parallels Plesk Panel 8.6 or lower or are using the DNS service BIND (Berkeley Internet Name Domain) with a version lower than 9.4.2 or Microsoft DNS without patch 951748, we advise you to update your DNS service.

To Update BIND

Windows Dedicated Servers with No Control Panel running Microsoft DNS

Run windows update to allow Windows to download and install all necessary security patches. This update should include patch 951748 which resolves this issue. If you have already installed all possible Windows updates then you have this patch installed and are secure.

Windows Virtual Private Servers (VPS) with No Control Panel Running Microsoft DNS


DO NOT attempt to run Windows updates. Our administrators will include this patch with their next round of updates to your Virtual Private Server (VPS) environment.

Parallels Plesk Panel servers use BIND as their DNS service. Any version of Parallels Plesk Panel below 8.6 should be upgraded immediately. You may either upgrade to Parallels Plesk Panel 8.6, or you will need to manually update your version of BIND on your server.
