vSphere Performance Overview Page – This Program Cannot Display the Webpage

When trying to browse the performance overview tab in the vSphere client you may get an error stating “This program cannot display the webpage” but at the same time, however, the advanced tab works fine.

Luckily, as vinf.net point out, this is pretty simple to fix. The cause of the problem is that the VMware Virtual Centre Management Webservices service is not running on the vCentre management server.

To fix the problem simply re-start the service manually on the windows server that has the vCentre management software installed on it.

vSphere 5 : System logging is not configured on host

After upgrading the company vSphere environment to ESX5 hosts with only relatively small USB SSD drives for internal storage I was greeted with the message System logging is not configured on host… when I first logged into the hosts using the new vSphere client.

Thanks to vmforsp for explaining that this can be resolved by adding the value “[] /scratch/log2 to the logDir variable in the hosts Configuration Tab>Software>Advanced Settings>Syslog>Global page as long as the SSDs have more than 1mb of available free space after installation.

Adding Single DNS hosts for external zones to a Windows DNS Server

Thanks to netlife for the following lifesaver when I was asked by a client to enable viewing of their own extranet sites via it’s external DNS address while the site was hosted in the same environment their own client PCs were. This caused complications as all external DNS servers, correctly, resolved the extranet.client.com address to the external IP address the client PCs were using for WAN access. This caused the page to fail to display as network traffic went out and back in on itself. I needed extranet.client.com to point to an internal IP address for internal users while still resolving to the external IP for external users and not effect the use of www.client.com for internal users which is hosted elsewhere:

A full solution is available after the jump:

Running an OEM operating system as a virtual machine – “This system is not supported platform”

I recently had to install Windows Small Business Server 2011 for a small client of ours. As with almost every install at the moment, the decision was made to do the install as a VM on ESX 5 as although there is no immediate benefit of doing this it potentially allows for the addition of other operating systems onto the same hardware in the future should it be needed.

An explanation of how this can be done is after the jump:

Battlefield 3 won’t open

Thankfully I’m amongst the lucky few who have a PC capable of playing this year’s most hyped game. Imagine my disappointment though when I first tried to run the game and nothing happened. No error, no window appearing quickly on screen before disappearing, no new processes shown in task manager – nothing!

After a lot of confusion I soon found the fix courtery a Kneg at toytowngermany.com.

All that’s needed is to remove the small TM from the end of the folder name which battlefield is installed to and the game runs perfectly from then on.

PES 2012 “Unable to access hard disk – Reselect hard disk”

While struggling to fix the FIFA problem described in my previous post I ventured back to the world of PES to see what had changed since I last played it back in 2008. It seems one thing that has changed is it doesn’t like users having their My Documents folders redirected to a network share.

The game itself was fine at first and I was able to begin getting into a new masters league session. When it came to saving the game and quitting for the day though I was greeted with the following error:

Unable to access hard disk – Reselect hard disk

Thanks to Heathen_666 at the PESFan forum I found the solution was quite simply to create a Konami folder within my documents folder. Inside the Konami folder create a Pro Evolution Soccer 2012 folder, return to the game and try to save again.

FIFA 12 Micro freeze

According to the EA forum it seems I wasn’t the only one to find this years incarnation of the FIFA franchise unplayable when I first installed it. Despite my PC being well above the minimum spec I regularly found the game freezing for a second or two at random intervals. This wasn’t the same experience as frames dropping, the game actually stopped before carrying on where it left off only moments later as if nothing happened yet at all other times the frame rate was perfect. This occurred repeatedly through each match making it infuriating to play.

Creating outlook rules based on domain names

I recently had a request from a client running Office 2007 to create
a rule that would take every incoming email from ”everyone@domain.com” and move them to a seperate folder (the deleted items folder as it goes, they were receiving excessive spam from a particular domain). As it has been a while since I’ve had to create my own new Outlook rules I set about creating a rule just using “@domain.com” and “domain.com”. Manually running the rule appeared to work, but further e-mails coming in were not deleted.

Thanks to Brian at www.office-outlook.com I came across the correct way to do this:

“The rule should use the condition “with specific words in the sender’s
address” and the specific words should be “domain” or “domain.com” (your
choice). Keep in mind that rule strings are substring matches so looking
for “domain.com” will also match on “otherdomain.com”. If you want to be
precise, then you can use “@domain.com” as the specific words. Be sure to
include the “stop processing more rules” action if you intend to have rules
following this one in the list.”

VMware vCenter Error Call “PropertyCollector.RetrieveContents” for object “propertyCollector” on vCenter Server failed

When trying to convert a template to a VM in order to make some adjustments to the image I came across the following error:

Call “PropertyCollector.RetrieveContents” for object “propertyCollector” on vCenter Server “VC” failed.

After a lot of confusion and frustration at a rather meaningless error message a fix finally came along courtesy of Yuri’s Technology Blog.

Simply removing the VM from the inventory and adding it back again from it’s location on the data store immediately fixed the problem. This seems to be an issue caused by the unique combination of the upgrade to vSphere 4.1 and the mounting of an ISO that no longer exists.

After re-adding the VM to the inventory it’s also recommended to change the device type of the troublesome VMs CD/DVD drive to either a client device or host device at least temporarily to remove the link to the redundant datastore ISO file.
