Symptoms

Consider the following scenario:

  • You install the iSCSI Target role service on a domain member that runs Windows Server 2012.
  • You try to create an iSCSI virtual disk that uses either the iSCSI PowerShell cmdlet or the "New iSCSI Virtual Disk" wizard.
In this scenario, you receive the following error message:
Unable to connect to the computer.
The iSCSI Target role service runs a verification of the server DNS name before it connects. This verification fails for domains that contain a single character DNS label.

Windows Server 2012 and Windows 8 file information and notes

Important Windows 8 hotfixes and Windows Server 2012 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/Windows Server 2012" 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
    6.2.920 0.21xxxWindows Server 2012 and Windows 8RTMLDR
  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.
  • 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.
