How to : Request (or renew) SSL certificate for Webinterface

This is how you request and install (+bind) a SSL certificate for example Citrix Webinterface.

Before you start you must now the external DNS name of your webinterface. In this case I use portal.company.nl
Test to make sure the webserver is responding and the firewall is configured. You notice a SSL warning/error. Something like this :


(The following screendump is a Firefox warning in Dutch Glimlach)

Now go to your Webinterface server and open IIS manager :



Go to the servername in the left pane, select Server Certificates in the middle pane and…


..select Create Certificate Request in the right pane.

Fill in the following screens :



Make sure the common name equals the name of your Webserver (Webinterface) on the Internet, for example portal.company.nl (For security reasons I greyed out some of the information in the screendumps)



Make sure you select at least 2048 bits. None of the SSL providers don’t accept anything less.


Provide a name for the certificate request file. In this file you will find the CSR. You will have to give this to your SSL provider. When you have done that, you can complete your Certificate Request in the same screen, only one option lower :



Unzip the file you received from your SSL provider and select next :


(Make sure that your friendly name is spelled correctly)

After this step your new certificate is imported :


Now you have to bind this certificate to the right port :portal011

Go to the default website, select SSL settings and choose in the right pane the option bind. Select port 443 and your newly imported certificate. Now stop/start your (web) services and you are ready to go :


How to : Extend diskspace Windows 2008 (R2)

Many times people asked me how to extend a disk or I see them running Gpart or CLI tools while it’s not necessary. For those people I decided to write this blogpost.

Step 1 : Extend your disk in VMware settings

Go to you vCenter server and extend the disk. Simply go to the server you wish to edit, choose edit settings and click on the hard drive you wish to extend. Make sure you select the right drive! Glimlach


Now just fill in the amount of disk space you want for this drive. In mine example (I took this picture after resizing the disk) it was 30 GB and I added 20 Gb so the total is 50 Gb of storage.

Step 2 : Check your drive and extend it Glimlach

Before I extended the drive it was 30 Gb, check this picture :


Now we are going to extend this drive. Go to server manager/storage.


Click rescan disks, because Windows doesn’t see the extra available space right yet. After the rescan you must see extra unallocated space. Now select the volume (partition) you wish the extend. See below :

extend disk

Just go through these simple steps :






Et voila, the disk is extended :
