The last couple days i shared what happened at the E2E virtualization conference in Barcelona.

This blog is about final day of the E2EVC.

We started the morning with a session with our E2EVC grandfather Carl Webster (@carlwebster) and Iain Brighton (@iainbrighton) about the great scripts Carl wrote to easily document your environment.
How they are working on improving the scripts with more performance so the scripts will collect and create the reports much faster.
They also work on a script template which you can use to easily create your own documentation script with the same slick output as Webster’s scripts have. Also the output of the script will be modified as there is now only a way to export it to Microsoft Word or PDF, but the future version will let you export to XML or plain text if you need to.
Iain and some other guys from the community are teaching Carl in how Carl can improve his programming skills to create better and faster scripts.

In the next couple days i will share what happens at the E2E virtualization conference in Barcelona.

This blog is about day 2 of the E2EVC.

The day started with a presentation about the HP Moonshot presented by Carl Webster (@carlwebster)
The HP moonshot is new technology from HP and it’s like having about 180 physical client machines in a box.
A client will have the power and feeling of a thick client, but the hardware is not on his desk but somewhere else. Continue reading »

SQL-Server-2012 Today I want to add a SQL database to the SQL server in my lab environment. The database I want to add is a sample database that I want to import in my environment to test some query’s.

The download for this sample database only contains a .mdf file and no LDF file (transaction log). When I try to add this database trough the SQL Management Studio I receive an error that the LDF is missing and that because of that the database can’t be added.

A few days back I had a minor issue with my VMware host. I wasn’t onsite to get behind the ESX host. There was also not a management network card installed like ILO or any other IP management tool. So my only applications where the vSphere client and Putty SSH Client.

I am a GUI guy and wanted to connect and see the console. So this is what I did.

Within some environments and especially an RDS or Citrix based SBC environment, there can be a problem with the root SSL certificates when using Office Communicator 2007.

In my case:

The first user on serverA who starts the Office Communicator won’t have any problems, because it can use the imported root SSL certificate to secure the connection. The second user (on serverA) who starts the Office Communicator will have problems, because the Office Communicator in the first session probably tries to change something and the root certificate is removed.

why? good question, but even Microsoft doesn’t know why, but it happens.

Ok.. you can fix this by doing the following steps:

One of the most important things to do when using Lync 2013 is to backup the Lync 2013 topology and configuration.
With these backup files and your ssl certificates you can restore your basic Lync environment (without the data).

With this powershell script you can easily backup these configuration files and as a bonus you can also backup the persistent chat database.

You have to run the script on a machine with the Lync cmdlets (Administrative Tools).

When you have a large Lync 2013 environment with several OU’s, you want to “Lync enable” users automatically, and maybe you require a specific user policy for those users. (As you can see i used a VDI policy in my example) With this powershell script you can add as many OU’s as you like as long as you separate them with a comma. Users to enable within a specific OU are selected by: AD account is not disabled, AD account has an e-mail address, AD account is not Lync enabled yet. When you fill out the configuration lines at the begin, your ready to go. You have to run the script on a machine with the Lync cmdlets (Administrative Tools). I’ve tested the script for Lync 2013 implementations.

Mastering Puppet by Thomas Uphill

When you are considered to be an experienced Puppet user or you just started using Puppet, this book will help you with all requirements on getting a good Puppet implementation.
The book is not only about Puppet… To get an enterprise ready Puppet environment, you will be guided through the configuration of all needed linux components which results in a scalable and high available Puppet installation.
Some other good topics are GIT version control, Private and Public modules, GitHub, reporting and troubleshooting.

The book is based on a RedHat/CentOS environment, so when you use an other Linux distribution, you have to change some of the commands but that shouldn’t be a problem for any experienced Linux engineer.

This book is a must read for those who will implement puppet on 20+ nodes.

You can buy the book over here
