A few days ago I tried installing Exchange 2016 on a 2016 server. I kept getting the below error:
“Install-WindowsFeature : ArgumentNotValid: The role, role service, or feature name is not valid: ‘Server-Gui-Mgmt-Infra’. The name was not found. At line:1 char:1 + Install-WindowsFeature Server-Gui-Mgmt-Infra –Restart + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidArgument: (Server-Gui-Mgmt-Infra:String) [Install-WindowsFeature], Exception + FullyQualifiedErrorId : NameDoesNotExist,Microsoft.Windows.ServerManager.Commands.AddWindowsFeatureCommand”
Exchange 2016 CU3
A quick Google search showed me this:
Unfortunately, Exchange 2013 will not be supported on Windows Server 2016 at all. Exchange 2016 will be supported on Windows Server 2016 at GA, however Exchange 2016 it is not guaranteed to work on TP5. Sorry for the inconvenience.
Network and directory server requirements for Exchange 2016
All domain controllers in the forest need to be running one of the following:
Windows Server 2012 R2 Standard or Datacenter
Windows Server 2012 Standard or Datacenter
Windows Server 2008 R2 Standard or Enterprise
Windows Server 2008 R2 Datacenter RTM or later
Windows Server 2008 Standard, Enterprise, or Datacenter
Active Directory forest
The Active Directory forest functionality level needs to be at Windows Server 2008 or higher.
DNS namespace support
Exchange 2016 supports the following domain name system (DNS) namespaces:
In Exchange 2016, IPv6 is supported only when IPv4 is also installed and enabled. If Exchange 2016 is deployed in this configuration, and the network supports IPv4 and IPv6, all Exchange servers can send data to and receive data from devices, servers, and clients that use IPv6 addresses. For more information, see IPv6 support in Exchange 2013.
The time on the Source Server must be within 5 minutes of the time on the Destination Server, and the date and time zone must be the same on both servers. If the Source Server is running in a virtual machine, the date, time, and time zone on the host server must match that of the Source Server and the Destination Server. To help ensure that Windows SBS 2008 is installed successfully, you must synchronize the Source Server time to the Network Time Protocol (NTP) server on the Internet.
TIP: We cannot change the Sync server time NTP without running Command Prompt (CMD) as Administrator.
Active Directory can’t work correctly (or at all) if the clock is not synchronized around domain controllers/member machines. Computers that are more than 5 minutes out of sync will not authenticate which is configurable by GPO.
We can use the Windows Time Service for clock synchronization: W32Time.
In my azure portal I created a few Virtual Machines and I wanted to turn one of these in a DNS server. Unfortunately I had never tried this in Azure, and I couldn’t get it to work due to the Network Security Group and Network Interface in Azure..
After adding a static IP address in Azure and internal it still didn’t worked. So I came up with the bright idea to just disable the network adapter in the VM and re-enable it after a few seconds to see if this would work.
Well what do you know? Sigh… disabling the Network Adapter of a Virtual Machine in Azure makes it lose it’s internet… I don’t know what I was thinking, but I accidentally disabled the network adapter
I tried re-starting the Virtual Machine with the hope I would be able to connect again, but no that didn’t work.
There is a ‘Redeploy‘ button in azure. I tried.. but no.
I knew from the old interface manage.windowsazure.com that you could change the VM size and it would remove conflicts and work correctly again. I had all my hopes on this.. but also.. NO! It didn’t work! See reference here.
Click on AddNow create a new Network Security Group (NSG)
Now we’ve created a NSG we can attach it to the Network Interface. Search for Network interfaces:
I choose a random network interface, because I didn’t create one in the first time.
Click the Network interface
Click Network Security Group
Now click edit
Click the NSG
Select the NSG you’ve created
okay, we have a network interface and a network security group. The new network security group now hangs on the network security group. Now, we must attach the VM to the new network interface through PowerShell
To use PowerShell with azure we need to install the Azure modules. You could install the PowerShell Gallery, or install it in a elevated PowerShell. The link is listed below is for the PowerShell Gallery and should you install yourself further.
Since a few days my Razer mouse kept hanging when I lift it off my mouse-mat. Having a Razer mouse randomly freezes while gaming it f*cking sucks.. I searched for a solution on Google and found one at steam. I’ve only perfect-ionized his tutorial so all credits go to Steam user bladesmc.
I’ve created a tutorial with screenshots.
FIX: Razer mouse randomly freezes
Find the Razer Synapse app in start.
Lets first go to performance
Set the Polling rate to 500. This should be the default, but lets check if it’s on 500.
Now let’s go to Calibration
Make sure surface calibration is enabled
If you have a Razer mat choose the first option, if you have a different mat please choose option 2. Now follow the steps that are on your screen.
This might also be a good one to know for future problems: “If you’re experiencing tracking issues, please manually reset your mouse by holding the left, right and scroll wheel mouse buttons for 5 seconds.
‘Razer Synapse is our unified configuration software that allows you to rebind controls or assign macros to any of your Razer peripherals and saves all your settings automatically to the cloud. No more tedious device configurations when you arrive at LAN parties or tourneys, as you can pull them from the cloud, and get owning right away.’
From their plugin page: “This plugin lets you place AdSense ads using a simple point-and-click UI rather than manually inserting snippets yourself. To insert AdSense ads without the plugin would first involve generating the AdSense snippet and then pasting the Adsense snippet into either the text of the site or directly into the PHP. Google automatically determines potential placements for AdSense ads, suggests an initial ad layout, and allows you to lay out ads on your site.”
Sounds great, except for when it gives you the following error code:
“Unable to apply changes to your site. Sorry we were unable to save your configuration. The request to your server failed with error code 500.“
Activating Google Ads in the Google Publisher plugin for WordPress will show the below image
After that screen, you get the following screen
have you installed the WordPress plugin WordFence? De-activate the plugin and try again to enable ads on your website.
It’s the Web Application Firewall feature that will prevent you from enabling ads. The Web Application Firewall stops you from getting hacked by identifying malicious traffic, blocking attackers before they can access your website. Powered by the Threat Defense Feed, it is automatically updated with new firewall rules that protect you from the latest threats. Even if you are running a vulnerable plugin or theme, Wordfence will protect you from being hacked by blocking attacks based on known and constantly updated attack patterns.
After configuring Azure Active Directory connect it will send you e-mails with Identity synchronization Error Reports. The reports show which active directory objects have sync errors. The Identity synchronization Error Report can be useful, but if you get one every 30 minutes I consider it as SPAM.
You cannot disable Identity synchronization Error Report e-mails. In the tutorial I’ll show where you can change your email address. Change the e-mail address to something legit for when you do need the reports.
Although most error report and notification are sent to the Global Administrators, the AADconnect Identity synchronization Error Report will only be delivered to the Technical Contact email address.
DirSync to sync your local on-premises Active Directory with cloud based services. dirsync is the easiest option to implement however it comes with less flexibility what you can change in the configuration and It doesn’t support multi-forest environments.
Azure AD Sync is advance version of DirSync, it support most of the functions of traditional DirSync, and adds extra functionality such as mutli-forest support and password write back. I recommend to use the Azure AD Sync tool because it’s more flexible then Dir Sync
Azure AD Connect is currently in Preview stage. It has many of the same features as DirSync and Azure AD Sync, its going to replace DirSync and Azure AD Sync and it has plans for many other features such as non-AD LDAP support.
Azure Connect is recommended for larger organizations that have greater flexibility requirements, it provides consistent experience in hybrid environments that may or may not entirely utilize Microsoft on premise solutions
I was having an issue for months now where my laptop goes to sleep while typing.
It was driving me crazy, but now I’ve found out why this was happening it actually made me laugh.
A few things I thought of what it could be:
Outlook crashes?? And my laptop goes to sleep.
I press a hotkey while typing.
Windows 10 sucks?
Dell laptops suck!?
I was able to use an USB keyboard without issues. At home I use a Razer keyboard and at work I could usually find an USB keyboard, but it was one of those Mondays again where everyone is at work and grumpy. I couldn’t find a keyboard so I my laptop went to sleep every 15 minutes…
I googled some, and probably the same as you: Laptop going to sleep while typing
“I’m a computer repair technician and suddenly one day I started having the same problem, 9-12-2011 in fact. I tried everything, reloading the computer, flashing the bios, changing all settings to never sleep, and none of them worked. I was still having the same problem with my computer going to sleep in the middle of my typing, all random of course, i could type a paragraph or only a letter, and suddenly wham it would go to sleep. I was very frustrated, so I sat down for an hour and thought about anything that had happened that day to try and figure out what might have happend. I didn’t want to think the worst (bad motherboard). It took me a bit but it finally hit me. I had bought this pretty new braclet that day, one of those magnetic ones that are supposed to help with arthritis and carpol tunnel syndrom.
As a computer tech i felt very foolish because as any of us in the field will tell you computers + magnet = trouble. I didn’t think anything of it when I bought it and had already forgotten I was wearing it. Bingo, took it off about 10 minutes ago and I’ve been typing like a mad woman every since. No problems what so ever. Just thought I would throw this out there in case you might just be wearing said kind of braclet.”
My lovely girlfriend bought me one of those Josh bracelet for my birthday! Problem solved woehoe!! an I issue I’ve been having for over a year! No more typing and laptop going to sleep…
