Install / deploy Office Professional Plus 2019

Microsoft released Office 2019 yesterday. But it seems Microsoft push very hard to get people move from traditional office to office 365.

After I login Microsoft Volume Licensing Service Center, I found that Microsoft stopped to provide the ISO for Office Professional Plus 2019. And Microsoft only provides the deployment tool to deploy office 2019.

Office Professional Plus 2019 will be released with Click-to-Run installation technology only. We are not providing MSI as a deployment methodology for Office Professional Plus 2019.

Ok, then how can we install Office Professional Plus 2019?

First of all, download Office_Deployment_Tools_2019_MLF_X21-88134.exe from Microsoft website.

Then create an xml file as following:

Please be aware “ProPlus2019Volume” is the only available channel for office 2019 “ProPlus2019Volume”.

3. Run below command to get office 2019 installed

And you can also download a copy of the installation files if you want via below command:

RDP failed, and got system event ID 36870 fatal error occurred when attempting to access the SSL server credential private key.

It’s a wired issue.
Port 3389 is open, and can telnet to it. But if try to RDP to the server, the RDP connection will failed immediately.
And in system event log, there is an error message said “Description: A fatal error occurred when attempting to access the SSL server credential private key.”

After investigation, found out this issue was caused by the incorrect file permission were set on files within C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys.

So the fix is, grant system full control access to folder C:\ProgramData\Microsoft\Crypto\RSA\MachineKeys as well as all files within this folder.

Increasing disk/zpool size of FreeBSDZFS disks in Linode

I’m running a FreeBSD instance in Linode. And FreeBSD is not the official supported OS in Linode.The disk type is set to raw to install FreeBSD.

And recently Linode upgraded my instance and the disk size is increased from 40G to 80G.

But when I login to the system, I found that my zpool is still 40G. But the disk is shown as 80G.

I tried to enable zfs autoexpand on my zpool, the same. Then how to increase the disk/zpool size?

First, re-write disk metadata

After this, gpart can show the real disk space info

Then, expand zfs partition

Then, expand the zpool


Don’t forget to write zfs info to disk
