SCVMM 2012 R2 – Fix for VM console access error : Virtual Machine Manager lost the connection to the virtual machine

In the last couple of weeks I’ve been installing and configuring a System Center Virtual Machine Manager 2012 R2 (VMM) environment.

At first all management was done from the VMM management server and console access to VMs from VMM was working fine. Later on the VMM console (and appropriate rollup) were installed on the laptop directly. Then when he opened the VMM console as a regular user and entered the administrator credentials on the VMM console. All was fine until he tried to access the console of VMs from within VMM, because then for most (not all VMs) he received the following error:

Virtual Machine Manager lost the connection to the virtual machine for one of the following reasons.

Another connection was established to the console of this machine
The virtual machine has been shut down or put into the saved state
The user credentials provided do not have the necessary privilege to connect

(0x0003, 0x0000)

Other connections were not established to the console of this machine and the virtual machine had also not been shut down or put into the saved state. The user credentials provided when connecting to VMM were of an administrator account with VMM admin permissions.

Since the administrator logs on to his laptop using a non-admin account, we first tried to run the VMM console “As Administrator” but this didn’t resolve the issue.

Then I googled the error and found this knowledge base article : VMM 2012 Self-Service users cannot open a console session to a virtual machine . The description didn’t really match our symptoms since the account specified to connect to VMM was an administrator account instead of a self-service user and it was possible to open a VM console session when the VMM console was opened from the VMM Management Server. To rule it out, we tested the proposed resolution and verified using Get-VMConnectAccess that everything was configured correctly.

The solution was to SHIFT+Rightclick on the VMM console shortcut and then choose “Run as different user” and enter the credentials of the administrator account. After that everything worked fine.

Microsoft – Preparing for free exam 74-409 Server Virtualization with Windows Server Hyper-V and System Center

Exam dumps

Unfortunately I’ve received numerous requests for an exam dump of 74-409 which really upsets me.

For those that are not aware of it, you are not allowed to share or use exam dumps. “If Microsoft learns that a candidate used a “brain dump” site to prepare for an exam, this candidate will be permanently banned or prohibited from taking any future Microsoft Certification exams and may be decertified from the Microsoft Certification Program. In addition, test scores and certifications, if applicable, may be revoked. These actions may be taken even if the candidate did not intend to defraud the Microsoft Certification Program.”

Preparing to take the exam

This is generally what I do for preparing to take the exam:

  1. Determine the skills that are measured in the exam 74-409
  2. View the online course Server Virtualization with Windows Hyper-V and System Center at Microsoft Virtual Academy (MVA)
  3. Reflect how confident you are that the online course has provided you with sufficient skills to take the exam.
  4. Optionally enhance your knowledge using:
