When I wanted to install CU11 for Exchange 2016, at the Prerequisites Check, I got the following error message:
"There is a pending reboot from a previous installation of a Windows Server role or feature."
I restarted the server twice, but still got the same message. After messing around with some registry keys and still no luck, I looked at the error message in more detail. The key part is "installation of a Windows Server role or feature". So this was not talking about a normal pending reboot Read more [...]
You can use the following command line to test an NTP Time Server (Telnet over port 123 does not work as it is using TCP and NTP servers use UDP):
w32tm /monitor /computers:pool.ntp.org
"pool.ntp.org" is just an example, you can use any other time server.
I recently had a problem on an Office Web App Server (Windows Server 2012 R2). To show a document in Web View, it had to fetch it from another server via HTTPS. This failed.
The ULS log showed:
"The request was aborted: Could not create SSL/TLS secure channel"
When I used Internet Explorer from the Office Web App Server, I could connect to the other server via HTTPS no problem. So the certificate was not the problem, it was trusted on the Office Web App Server.
After hours of searching, I Read more [...]
If you need to synchronize the time via the Internet on a Windows Server, it is best to configure this via command line. Find below the commands you need (Open CMD as Administrator):
w32tm /config /syncfromflags:manual /manualpeerlist:"pool.ntp.org" /reliable:YES /update
w32tm /config /update
"pool.ntp.org" is just an example, of course you can use other time servers.
If you are not sure if the time of your Windows Server or Client is synchronized properly or if you would like to know which is the time source, you can use the following command lines (Start cmd with Administrator privileges):
net start w32time
w32tm /query /status
You should see something like this:
C:\Users\Administrator>w32tm /query /status
Leap Indicator: 0(no warning)
Stratum: 2 (secondary reference - syncd by (S)NTP)
Precision: -6 (15.625ms per tick)

The Windows 10 Start Menu is not as customizable as it used to be in Windows 7. While the part on the right (the tiles) can be easily removed and added by right-clicking them, the traditional part on the left (folders and shortcuts) is not customizable any more. In Windows 7, you could right-click on a shortcut and then delete or rename it. Not any more in Windows 10.
There are tricks to modify the Windows 10 Start Menu shortcuts anyway. Find the instructions to do so below:

Some Windows 10 apps cannot be uninstalled, even not with Power Shell commands. One example is the Edge browser. But you can disable those apps by renaming the folder that they are stored in.

SPN means "Service Principal Name". In Active Directory you can set an SPN with the command line tool SETSPN. Find below some usage examples which I use often:
setspn -Q http/www.mywebsite.com ==> Check if the SPN "http/www.mywebsite.com" exists
setspn -L MyServer ==> Show all SPNs for MyServer
setspn -X ==> Search for duplicate SPNs in the current domain
setspn -S http/www.mywebsite.com MyServer ==> Set the SPN for a specific Server object in AD. This also checks for duplicate Read more [...]
