Contacts CSV Import into Microsoft Exchange 2013 Public Folders

This was a ripper of a project. It allowed me to get my hands dirty with PowerShell and using the EWS Managed API with Exchange 2013 SP1. The code for this came from various sources and I have hand picked the bits I needed to make it all work. I have also had to add code to make the additional fields work and to vet the information that comes in from the CSV. How is this different to anything else out there? Simple. It contains nearly every field that can be imported into a Contact!! Yep. All those miscellaneous fields and User Fields!!!! Everything else on Google either only does… Read More

Drive Letter Substitution

Drive Letter Substitution – Removing a Hard Drive

I will give you a run down on how this happened. Was converting a physical server to a virtual server and ran with VMWare Converters defaults. Originally the Physical Server has two drives, C: and E:, which were now mapped to two VMDK files located in the same datastore. But this really wasn’t what I wanted. May be I should have paid more attention or planned a little better, but I didn’t, and didn’t pick this up until after waiting out the conversion process. So what do you do when you have more disk than you want? Simple. Get rid of them!! The best solution was a modified version of… Read More

How to create a Thin PC from a Windows PC

Done this one a few times. Clients with old PC’s and a Terminal Server. Its a simple Batch Script, an RDP file and a quick REGEDIT and your old PC boots straight into a Terminal Server Login Screen! I’ve attached the files that I have used in the Past. It is a reasonably simple setup. Step 1. Edit the Running Batch File (TSC.bat). You will see it has an PING IP Address in it. Change the IP Address to your Terminal Server IP. This is simply telling the Batch File to wait until it can Ping the Server. One of the biggest problems I have come across in the past… Read More

Veeam Surebackup Virtual Lab

Seems easy enough right? Forget it. The functionality is good for checking that your backups worked but that is about it. Do anything Lab related and mess around a lot and you can easily lose it all. As I found out! Veeam restores VMs into the Lab but they use a change log. Once the VM is shutdown, bye bye changes. If you, like me, spend a week messing around and want to change the actual VM Settings… DAMN!!!!! So why do I still LOVE it???? I set it up for a client but instead of restoring Veeam Backups into it, I P2V and V2V (even Cloned!) machines into it… Read More

SSL Certificates – Open SSL – Private Key

SSL Certificates are a critical part of any hosted page or service that operates on Port 443 or SSL!!! Great program for messing around with SSL Certs and Private keys is Open SSL One thing I find that I am constantly doing is pulling out the Private Key from a PFX File that I have created as a backup for my SSL Certificate.
