Invalid Exchange Server version using Veeam Backup for Microsoft Office 365 #updated #withSolution

Update: After contacting Veeam support they attended me that there is a private fix voor version 912.

  • stop all jobs
  • stop “Veeam Backup for Microsoft Office 365 Service”
  • replace Veeam.Ews with the DLL from the archive in C:\Program Files\Veeam\Backup365 (don’t forget to back up the original DLL)
  • Start “Veeam Backup for Microsoft office 365 Service”
  • retry the job


As you can see the problem is solved and I’m able to backup Office 365 again!

People (including me :-))  are reporting problems using Veeam Backup for Microsoft Office 365. It seems that Microsoft made some kind of change on their back-end. At this time Veeam reports that they are looking into the problem..

I’m running Version…. a newer version isn’t available on the general download site. So upgrading the Veeam software isn’t the solution for now.


Don’t seem to be (Windows) update related. Before and after updating my test server I receive the same error. 🙁


When there is a solution I shall mention this in this blogpost.

How to fix VM guest only showing 1/4th of the console window

I’ve noticed that when I’m running on some (high resolution) laptops I’m unable to see the whole console screen of a VM guest. Connecting those laptops to a docking resolves the problem.

As you can see in the following example you don’t see only a quarter of the console session :


After some investigation I found the solution. Open the shortcut of the VMware Client and open the properties. Enable the disable display scaling option.


Make sure you save the settings and try again.


As you can see in the above example, the whole screen is displayed!

How to configure PXE booting using PfSense

For some testing in my lab environment I needed PXE boot to work. This is how I configured PfSense to support PXE boot. In this scenario I wanted some Windows and Linux devices to boot to an imaging environment. For the Windows devices I needed option 66 en 67 but somehow when I specified those settings in PfSense I didn’t got it to work. The solution was very simple :

Log on to the Webinterface of PfSense, go to services/dhcp server.

Specify the following options :

  • IP Address of TFTP server
  • Enable network booting yes
  • Next Server (= IP Address of TFTP server)
  • Default Bios file name (= filename of legacy of UEFI bootfile name, in my case undionly.kpxe)


Save these settings and you’re all set! You don’t have to specify the 66 and 67 settings!

How to fix non booting laptops hanging at HP logo 2

While working on a large deployment project I noticed a strange behaviour with HP laptops. After deploying some laptops didn’t pass the HP logo. Nothing happend.


After searching the internet and contacting HP (no solution) the solution came through (by mistake :-))

When you see the above hp logo and your laptop doesn’t start through…. press the up (no keypad) or the 8 (with the up arrow) and voila!


After pressing the up arrow the problem is solved. 🙂

Troubleshooting KACE 1000 client issues

I recently ran into some issues with installing the KACE 1000 client. KACE 1000 is the KACE Systems Management Appliance from Quest software.

In this example I want to push the agent to a specific client and that fails.

Check the logging

First step is to check the logging. Go to settings, Provisioning, Provisioning results. There you find the logging of the deployment tasks.


When you want more information you can easily click the specific task and see more details :


Try installing the agent manually

You can save youreself a lot of time troubleshooting the issue when you try to install the agent manually. This way you can quickly troubleshoot the problem and often (when you have multiple clients with problems) the solution you’re going to find is also the answer for your other clients.

Go to the machine you want to install the client on. Open File Explorer and browse to the following directory:


In my example I want to install the client on a Windows device. (There are also Linux and Mac clients)

Use the agent_msi_provision script to manually install the K1000 client. The script automatically tries to detect the K1000 server. Sometimes (due to DNS problems for example) it fails to determine the K1000 server. You can use the command line option %1 for specifying the K1000 server. So use the following command agent_msi_provision In my example the IP address of the K1000 in the demo environment has the .41 IP Address

Wait a minute and check in the Devices windows of the K1000 for the specific client.

Check network connectivity

When that doesn’t work (the first step often doesn’t :-)) check the network connectivity. Can you ping the client <> K1000? Are the right firewall rules in place? You can decide to temporary disable the firewall (and after adding it to K1000 use the K1000 options to enable the firewall again). I don’t encourage disabling firewalls, so use this tip only for troubleshooting.

net stop wuauserv
sc config wuauserv start=disabled (to keep it disabled after a reboot)

Turn on Network discovery and turn on file and printer sharing.


Check sharing and security settings

The installer uses the default ADMIN$ share to connect to the client to install the software. Go to the client and browse to the \\clientname\ADMIN$ share. Can you see the files using the account you specified in the K1000 provisioning task? No? Check if the shares are available.


User account control (UAC) must be configured in one of two ways: Turn UAC off or set user account control: run all administrators in admin approval mode to enabled.

Ofcourse the specified user in the provisioning job has to exist and has local administrator rights.

Install the client using winrm method

I found installing using the winrm service to be a quick fix for me. You can easily enable that on the provisioning task :


For this to work, the winrm service has to be enabled and running :


Wrap up

So in a nutshell :

  1. Check the logging
  2. Try troubleshooting installing the K1000 using manually install
  3. Appropiate account? (UAC disabled?)
  4. Check network connectivity (DNS/Firewall/same domain?)
  5. Fall back to WinRm method
