Amazon WorkSpaces Windows Client Registration service

I normally use for work at least 2 physical devices so I’m not affected too much about any hardware or software malfunction.

I work with a lot of customers and I’m using my personal devices for work, so I always get into trouble. Luckily, I know somebody doing IT which helps me from time to time 🙂

 

It was the case also for the Amazon WorkSpaces Client which for some days, didn’t wanted to register with the AWS WorkSpace that I had configured, showing an error for Registration service in the service checks window. It always told me to check my internet connection although that my Internet connection was running fine.

I also checked and re-checked firewall rules but still no luck, until this small issue was a challenge already 🙂

2017-03-05_02-03-07_amazon-workspaces_000341

 

I got this issue fixed by going to my user profile and deleting the Amazon WorkSpaces config folder.

To do this, go to:

1. Close the Amazon WorkSpaces client

2. Open Explorer and go to:

C:\Users\%username%\AppData\Local\Amazon Web Services\

3. Make a copy of the Amazon WorkSpaces folder and delete it afterwards

4. Open the Amazon WorkSpaces client and configure the client with your WorkSpace info

5. Enjoy the easy fix!

 

Cheers

This edition cannot be upgraded – How to activate Windows Server 2016 Evaluation

 

 

I happen to have more than a couple of dozens Windows Server VMs in my HomeDC, starting with Server 2003 and ending with (the gorgeous) Server 2016.

I tested 2016 along with various products (including XenDesktop, Horizon View, VEEAM) since I first got my hands on the Tech Preview 1 and as per today, I have close enough to 15 VMs running with the 2016 Evaluation version. I didn’t really wanted to reinstall EVERYTHING just because Windows doesn’t want to switch “automatically” from Evaluation to the new Product Version for which I had a license, so I started digging into DISM.

image

 

So, what’s to be done?

Open an elevated Command Prompt (Win+X, then A) and type:

DISM /Online /Set-Edition:ServerStandard /ProductKey:Your-VLK-Product-Key-For-WindowsStandard /AcceptEULA

NOTICE: If you have a Datacenter edition, you might need to set the edition to “ServerDatancenter” as it was the case for me.

image

 

At the end (yeah, it takes a while…), the process might request a reboot, so reboot your server and then check the Activation status.

PS: Not sure if this works for the Core edition. Didn’t had the time to test, but I guess it’s not working. Sad smile

How to delete orphaned VMs on VMware vCenter 6.5

Before VMware vCenter 6.5, deleting orphaned VMs was really easy. You just needed to connect with the VMware vSphere Client (the fat client) to the vCenter server, create a new folder, move the broken stuff in it, and delete the folder.

Well… on vCenter 6.5, that’s not possible anymore as you can’t connect with the vSphere Client on the vCenter server, just to the ESXi.

The only workaround for this was to use PowerCLI (version 6.5 can be downloaded from here)

After installing PowerCLI, start it from your Desktop or from the Start Menu and type:

Connect-VIServer -Server YourvCenterServer

You’ll now be prompted for credentials needed to login in vCenter.

2016-12-13_10-12-48_vmware-powercli-6-5-release-1-build-4624819_000228

The following command will show you all VMs registered in vCenter

Get-VM -Name *

And to delete the orphaned one(s)

Get-VM -Name YourOrphanedVMName | Remove-VM

To see all running VMs and a bunch of other info type:

Get-VM | select * | Out-GridView

When you deleted all your VMs, you should also check to see if the process left behind some crap like unused VMDKs.

Good luck!

VMware vCenter Server Appliance 6.5 – failed to boot – Failed to start Network Service

2016-12-10_19-12-53_ogsvcs01-vmware-remote-console_000215

If you ever encounter an issue with the vCenter server that’s so bad that the server itself doesn’t start, well try the following:

fsck -fy /dev/mapper/log_vg-log

If it tells you that it fixed something, just press CTRL+D and let the damn thing boot.

My LAB environment’s “reliable” storage system is a Synology NAS (XPEnology actually) and I present iSCSI LUNs out of it for all my devices, including the 2x SUPER-AWESOME Supermicro SYS-5028D-TN4T that I’ve aquired in June 2016.

So, from time to time (to be read as less as possible) I reboot the NAS due to different reasons but nothing really bad happened until now as I do my homework and shutdown anything that might use that shared storage system. This time, I forgot to shutdown the vCenter server, which you guessed… was using one of the iSCSI LUNs as its underlying storage and one of the partitions got corrupted and the vCenter Server crashed and failed to boot.

Hope this helps you. I wondered a bit until figured out what’s wrong 🙂

NVIDIA M60 / M6 Problems – check your card in “graphics” mode!

Virtually Visual

This blog only applies to M60 / M6 (Maxwell generation) GRID cards. It is not relevant to GRID 1.0 (K1/K2 cards).

Try this first!

If you are experiencing issues with a new M60 / M6 card, please run this command:

  •  lspci –n | grep 10de

You should get something that looks like:

[root@SAGRID-ESXi5:~] lspci –n | grep 10de

0000:04:00.0 Class 0300: 10de:11bf [vmgfx2]

0000:05:00.0 Class 0300: 10de:11bf [vmgfx3]

0000:08:00.0 Class 0300: 10de:11bf [vmgfx0]

0000:09:00.0 Class 0300: 10de:11bf [vmgfx1]

0000:86:00.0 Class 0300: 10de:11bf [vmgfx4]

0000:87:00.0 Class 0300: 10de:11bf [vmgfx5]

If your system reports 0302 instead of 0300, the GPU is in “compute” mode. If it reports 0300 as above then it’s in “graphics” mode and this is not the cause of your issue.

If you notice the GPUs are in compute mode – then use the gpumodeswitch utility and change it to graphics, make sure you reboot the server to apply…

Click and Right click not working on Windows 10 Start Menu

I found out the hard way, that by removing the AppX software packages that come pre-installed in Windows 10, the “immersive” shell might not work as supposed.

To be more precise, clicking and right-clicking the Start Menu will not do anything.

 

In order to solve this, all AppX packages will need to be reinstalled and the following command will fix the issue:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

Announcement – VMware VSAN 6.2

vcdx133.com

vcdx133 VMware Virtual SAN version 6.2 has been announced.  Two big improvements are the inclusion of Data Integrity (checksum on write and read) and improved UI integration into the vSphere Web Client.

This is the fourth major release of VSAN functionality.  VMware is definitely taking this product seriously and trying to evolve VSAN to a true enterprise-grade SDS stack.

If you are a customer that has an extensive investment in the VMware eco-system from a people, process and technology perspective, then VSAN could be a good choice if you are dipping your toes into the HCI space for a small part of your infrastructure.  Use-cases such as Management, DMZ, PCI, Dev/Test and EUC Clusters are a great fit, in my opinion.  If you are selecting an enterprise-wide solution for mission/business critical applications, then a more mature SDS vendor would be worth considering to minimise risk.

Citrix StoreFront authentication in SSO mode

I found something extremely intriguing about StoreFront and authentication and wanted to share it with the community.

Let’s take StoreFront 3.0, although I bet it was there since beginning.

When StoreFront is configured in SSO mode you have two types of authentication:

  1. From the Internet (via NetScaler)
  2. From internal network (no NetScaler involved)

The Internet authentication is pretty straight forward. StoreFront SSO is not active and users must login the old way, with username and password.

Internet Authentication (NO SSO)

The difference can be seen when SSO authentication from internal network is being used and one specific feature is missing. Explicitly.

And apparently, there’s a reason for it.

In StoreFront’s top-right side, there’s a drop-down menu that appears when clicking the user’s name. The drop-down menu is by default populated with the Activate” and “Log Off ” options, but the Administrator can add more options there.

But where’s the “Change password…” option?

Well, I mentioned that this feature is explicitly removed when SSO is active, and the reason is very logic and I’d give lots of Kudos to Citrix for this.

The reason for the missing “Change password…” option is just one: SECURITY.

 

As mentioned by some friends at Citrix, the logic behind this is quite simple. When an user logs in to his computer and SSO is active, the option is missing in order to protect it’s password, as he might leave his PC unlocked and “a friend” could change the password from StoreFront. And because SSO is active, the “friend” would not be asked for the current password.

If you have like me, clients that need to change passwords from StoreFront, tell them to connect with the alternate login method (Username and Password) and the “Change password…” field will appear where it should be.
