This article describes an issue that occurs on a Remote Desktop Session Host (RD Session Host) server that's running Windows Server 2012 R2. A hotfix is available to fix this issue. The hotfix has a prerequisite.

Symptoms

When the print spooler crashes and then restarts, your printing job is sent to a redirected printer. However, the redirected printers go offline after the print spooler is restarted, and your document can't be printed successfully.

Cause

This issue occurs because for the redirected printers, the PrinterOnLine registry value can't be deleted correctly because of a bad file path. This causes the redirected printers to remain offline after the print spooler is started.

Resolution

To fix this issue, we have released a hotfix. Even though this issue is observed only in Windows Server 2012 R2, the hotfix also applies to Windows 8.1 and Windows RT 8.1.

Important If you install a language pack after you install this hotfix, you must reinstall this hotfix. Therefore, we recommend that you install any language packs that you need before you install this hotfix. For more information, see Add language packs to Windows.

Windows 8.1 and Windows Server 2012 R2 file information and notes

Important Windows 8.1 hotfixes and Windows Server 2012 R2 hotfixes are included in the same packages. However, hotfixes on the Hotfix Request page are listed under both operating systems. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 8.1/Windows Server 2012 R2" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.

  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version

    Product

    Milestone

    Service branch

    6.3.960 0.16 xxx

    Windows 8.1, Windows RT 8.1, and Windows Server 2012 R2

  • The MANIFEST files (.manifest) and the MUM files (.mum) that are installed for each environment are listed separately in the "Additional file information" section. MUM, MANIFEST, and the associated security catalog (.cat) files, are very important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
