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 [...]
I come from a Windows and physical keyboard world, so things that are simple in Windows seem very complicated or undoable in iOS. For example, shutting down an App (as simple as clicking the red X in the upper right corner of a window) didn’t seem possible in iOS.
Find below some shortcuts that show how to do the “impossible”:
Go to Standby: Press the Standby button shortly.
Wake up from Standby: Press the Standby button shortly.
Go to Home screen: Swipe up from the bottom.

Sending emails with a S/MIME signature has 2 advantages:
It ensures that the sender is really who (s)he says (s)he is (prevents spoofing)
The content of the email has not been changed or tampered with
It is fairly easy to implement and it works with any recipient as most email clients (including web clients) support S/MIME. Even if a client would not support it, the recipient can still read the mail.
First, you need to get an official certificate for your email address. There are different 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)

You can use HP ILO to upgrade its own firmware, by uploading the firmware file (e.g. ilo4_255.bin) via ILO web console. This is straight forward and clear.
But the ILO can do much more (but this is really a bit hidden in the web interface). From the help notes:
The following firmware types can be updated from the Firmware Update page:
System ROM (BIOS)
Chassis firmware (SL and XL servers)
Power Management Controller
System Programmable Read more [...]

Right-click on the Desktop and choose New > Shortcut
In the "Location of the item" field, type
In the "Name of the shortcut" field, type Windows Update
Click on Finish
While this works, it has one disadvantage. Clicking the shortcut always first Read more [...]
Regular Expressions (RegEx) can be quite complex to understand. For a simple start, I have made a "Regex for Dummies" guide, which you will find below:
In order to make it an easy start, I made 2 assumptions:
As an input string, we just look at one line. Multi-line strings are excluded from this tutorial.
A result can only be "True" or "False". "True" means the Regex matches the input string at least once. "False" means the Regex does not match the input string at all.
In Read more [...]
