Blinking desktop icons

Today I faced a problem where a user had blinking desktop icons on a terminal server, some said that I had to delete his local account but this was his third time for this user.

Google wasn’t a help this time where some bloggers were saying you’ll have to delete de icon cache.

 

The solution I have found is easy to use but not where I first thought of.
Back in the days I had a similar problem on a Windows 98 SE machine but didn’t thought it would work on a newer Windows version.

 

Go to Internet Explorer and open the settings (or for the advanced user run “inetcpl.cpl”).

On the “Advanced ” tab you’ll have a button to reset your settings

After resetting the Internet Explorer Settings to default the blinking icons stopt blinking.

SCCM 2012 on Server 2016

After successfully installing SCCM 2012 on a Server 2016 in my home lab I had some problems with the Application Catalog.

The problem I was facing was that I couldn’t install the Application Catalog.

When digging in the CM Trace Log Tool, I’ve discovered that a MSI package couldn’t install on the server, I tried to install it by double click the MSI file and discovered that the MSI couldn’t handle IIS Version 10, it gave me the error:

“Application Web Service requires IIS 7 or higher”

After some search on the web I found a tool named Orca MSI editor to edit the MSI files.

 

 

Install Orca and make a copy of the MSI files below:

  • Awebsvc.msi
  • Portalweb.msi

These files are located in the following directory:

C:\Program Files\Microsoft Configuration Manager\bin\X64

 

Open each copy of the file in Orca and edit the following line:

From: (NOT REMOVE) AND (IISVERSION < “#7”)

To:      (NOT REMOVE) AND (IISVERSION < “#10”)

Save the MSI files and replace the files on the server.

After replacing the MSI files you can safely install the following roles on the SCCM server:

  • Application Catalog web service point
  • Application Catalog website point

To verify that SCCM installed the roles in IIS, open the IIS Manager and expand the “Default Web Site”

You’ll see that there will be a “CMApplicationCatalog” and a “CMApplicationCatalogSvc”.

Adding SSL certificates on the NetScaler

Note: This blogpost is also posted on my personal blog.

There are a lot of different certificate file formats that can be involved in a SSL certificate implementation as explained in my previous blogpost. This blogpost focused on the different methods to create and import these files onto the Citrix NetScaler and showing you how to assign the right SSL certificate to your virtual server for load balancing or gateway services. You can read all about the different certificate (and certificate archives) file formats in my previous post.

SSL Certificates Explained

Note: This blogpost is also posted on my personal blog.

Using SSL certificates to secure website communications is more and more a standard procedure. Even internal websites are relying more and more on public or private PKI infrastructure and Certificate Authorities. And as each certificate is only valid for a limited period of time, you’ll find yourself renewing more and more certificates on a yearly basis. So let’s check out the different file extensions we are facing when working with certificates.

Automated USB wim deployment

For a customer I was asked to create a easy way to deploy  images to thin clients and thin pc’s. The preference was to use a USB stick as network was not a option.

This brought a number of challenges that I will discuss in this blog.

Fase 1 -  Create the WinPE Usb stick
Fase 2 – Add the needed packages to the USB stick
Fase 3 – Get and prepare the WIM file
Fase 4 – Give WinPE Menu options to choose from
Fase 5 – Deploying the WIM
Fase 6 – Renaming the deployed computer
Fase 7 -  Recreate the BCD
Fase 8 – Re enable the write filter

Before we can start, we need a bootable USB stick with WinPE.
To create this we need a deployment server preferable with Windows server 2012.

Lync 2013 Full client installation using a MSP

This blog is about the installation of the Lync 2013 Full client (part of the Office 2013 installation).

– Introduction
– Using OCT
– OCT/MSP bugs and fixes (Lync only installation problem)

Introduction:

When you want to install the full version of Lync 2013 client instead of the Lync basic client version, you have to use the Office 2013 installation media.
This is because the Lync Full client is now part of the Office suite and therefore not available as separate installation anymore, as it used to be.

Because there are enough reasons to not upgrade the whole office suite to version 2013, you have to create an MSP file with OCT (Microsoft Office Customization Tool).
For the most IT professionals the OCT isn’t new, but for those who are new to OCT i will explain the basics of it.

  • How to install VMware view client
  • How to enable EWF (Enhanced Write Filter) on the T5740

But first things first lets install WES7 on a 2gb flash drive.
