I have been working on a project to change from a six node Nutanix VMware cluster to a Hyper-V one, simple I thought. Here was my intended method:Read more
- Remove three nodes
- Reimage to Hyper-V using the Phoenix package and the Foundations VM
- Create a new cluster.
- V2V all the VMs using SCVMM
- Destroy the old cluster
- Reimage those nodes and add to the...
So you try to mount an ISO in the VMM library with the shared option and get the following error: [error] Error (12700) VMM cannot complete the host operation on the (SERVER FQDN) server because of the error: 'VMName' failed to add device 'Virtual CD/DVD Disk'.

So you create a new Generation 2 (Gen2) virtual machine and install either Windows Server 2012 or 2012R2, you customise it and then you convert it in to a template in SCVMM. All is normal. You go to deploy that template from the library and it fails with the following: [error]VMM cannot find the device or this device is not valid for a...Read more
So I have been working recently on a large VDI project based on the Nutanix converged platform, which I have used before but only in its VMware hypervisor version, this time however the solution was to be based on Hyper-V. So here is what I have learned...... The documentation is not complete or entirely accurate!!!!! However...Read more
Nutanix now provide a hypervisor agnostic platform, which is great however if you do not clearly state which hypervisor you want it will come out of the factory with KVM installed, as I found out on my last project. When I contacted Nutanix to ask what to do to change it to Hyper-V I was braced...Read more
Recently I have started carrying out my Lync 2013 installs on to Windows Server 2012 R2 and have noticed a strange issue from time to time. When I open the Lync Management Shell (PowerShell) from the start menu, the command window opens but I never get a prompt displayed, it just sits there as a blank window,...Read more

With the release of UAG SP4 that gives support for Windows 8.1 and Internet Explorer 11 clients I have had a few people ask me about why their pre-upgrade configuration has disappeared. The simple answer is that the configuration schema has changed between the updates and hence it does not import...Read more
Operatons manager out of the box allows for the detection of Virtual Machines and this detection can be used to build a group for Virtual Servers. The only problem is that this is detection is only for Hyper-V, so what happens if you need to detect and group VMware VMs? Well the solution is pretty simple. Within the SCOM console, open...Read more
I have recently been working with a customer who had a half implemented Exchange 2013 infrastructure but were suffering issues where no client could connect. After a little investigation the World Wide Web Publishing Service would not start due to a dependency failure on the Windows Process Activation Service. Looking at Event Log I could see...Read more
So you have taken the leap your going to build that Hyper-V 2012 Cluster. You build your hosts, you configure Hyper-V and Failover Clustering.

When I went back into the console and the server was not in the agent managed secion, so i went into pending management to do the approval again but then agent had disappeared. So a...Read more
I have been pulling some licensing quotes together over the last few days for a customer and the LAR I deal with suggested that I look at using some Office 365 Licensing so as to cover the Office and CAL requirements. OK I thought but the customer uses RDS which last time I looked meant...Read more

So your making use of all those new products, Lync 2013, Exchange 2013 and SharePoint 2013 but now comes the task of Lync 2013 integration. So lets make a start and configure the basics so that Lync 2013 can use Exchange 2013 for Archiving and Contact Storage (UCS).
