VMware Horizon View Agent, fix VPN using error

Can not reconnect to machine via Horizon View after setup VPN connection.

When you install View Agent on a virtual machine that has more than one NIC, you must configure the subnet that View Agent uses. The subnet determines which network address View Agent provides to the View Connection Server instance for client protocol connections.

On the virtual machine on which Horizon Agent is installed, open a command prompt, type regedit.exe and create a registry entry to configure the subnet.

For example, in an IPv4 network: HKLM\Software\VMware, Inc.\VMware VDM\IpPrefix = n.n.n.n/m (REG_SZ)

In this example, n.n.n.n is the TCP/IP subnet and m is the number of bits in the subnet mask.


In releases earlier than Horizon 6 version 6.1, this registry path was HKLM\Software\VMware, Inc.\VMware VDM\Node Manager\subnet = n.n.n.n/m (REG_SZ). The old registry setting is not used with View Agent 6.1 or later. If you upgrade View Agent from an earlier release to version 6.1 or later, make sure to use the current registry setting.

Remote Desktop Gateway: force use NTLM

On Windows Events (Microsoft-Windows-TerminalServices-Gateway/Operational) appears records with event ID’s 312, but the connection does not authenticate successfully. Remote Desktop Gateway does not support Kerberos authentication, which use Remote Desktop Client with version >= 8.0


  1. On Remote Desktop Gateway server set the EnforceChannelBinding registry value to 0 (zero) to ignore missing channel bindings on the Gateway server. Reboot for applying changes.

    HKLM\Software\Microsoft\Windows NT\CurrentVersion\TerminalServerGateway\Config\Core

    Type: REG_DWORD

    Name: EnforceChannelBinding

    Value: 0 (Decimal)

  2. On client change Local Policy LAN Manager Authentication Level. Adjust the NTLM Manager setting on the client to be "Send LM & NTLM - use NTLMv2 session security if negotiated".

Howto Shrink a Thin Provisioned Virtual Disk (VMDK)

Virtual Machine Preparation (Windows)

Windows does not automatically zero deleted blocks. Microsoft provides a tool that can zero blocks after while deleting a file or zero out the entire free space. This is required to reclaim space back from the virtual disk.

  1. Download SDelete (http://technet.microsoft.com/en-us/sysinternals/bb897443.aspx)
  2. run sdelete.exe -z [Drive]

Virtual Machine Preparation (Linux)

Linux does not zero deleted blocks too. There are various tools available to create zeroed blocks. The best known tool is dd which should be available on all systems.

  1. Identify free space with df
  2. Fill the free space with dd
vma:/mnt/data # df -h
vma:/mnt/data # dd bs=1M count=8192 if=/dev/zero of=zero

This will zero 8GB of the available 8.2GB (1MB Blocksize * 8192 = 8GB). Please note that you virtual disk file (VMDK) will grow to the full size during the process.

Shrink VMDK File

  1. Power off the Virtual Machine, or disconnect the virtual Disk you want to shrink
  2. Connect to the ESXi Host with SSH
  3. Navigate to the Virtual Machine Folder
  4. Verify disk usage with du
  5. Run vmkfstools -K [disk]
  6. Verify disk usage with du
root@esx3:/vmfs/volumes/ds1/vma $ du -h vma_1-flat.vmdk
7.9G vma_1-flat.vmdk

root@esx3:/vmfs/volumes/ds1/vma $ vmkfstools -K vma_1.vmdk
vmfsDisk: 1, rdmDisk: 0, blockSize: 1048576
Hole Punching: 25% done.

root@esx3:/vmfs/volumes/ds1/vma $ du -h vma_1-flat.vmdk
1.9G vma_1-flat.vmdk

After you install Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 Service Pack 1 (SP1) using integrated media, you may see the following WMI error is logged in the application log after every reboot:

Details - Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage > 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected.
