MSN Video – Internet TV for Media Center – Broken?

October 6th, 2009 admin

Microsoft recently released a Beta of Internet TV for Media Center.  Here’s a mention from Engadget:

Engadget

Worked great when it was first released, however I’m now seeing the following message when trying to use on different PCs:

APPLICATION ERROR – There is a problem with the application at this time. Try again later.

Anyone have any tips on when the service will resume?   Only played with it for a few days and already miss it!





Windows Update Failed – Error 0x80071a2c

October 6th, 2009 admin

This one took some investigation!

The Vista PC in question had 6 Windows Updates all failing with the same error code : 0x80071a2c. After several attempts at rebooting and installing the updates, I decided to delve deeper.

Looking in c:\windows\windowsupdate.log I found the following errors:

WARNING: Got extended error: “POQ Operation HardLinkFile OperationData \SystemRoot\WinSxS\x86_microsoft-windows-help-browser.resources_31bf3856ad364e35_8.0.6001.18702_he-il_9475a540718490ed\browser.h1s, \??\C:\Windows\Help\Windows\he-IL\browser.h1s”

Now, from what I found, the POQ error is due to Windows Update creating a hardlink between the two “browser.h1s” file locations specified above.

But the source file above doesn’t exist in the winsxs folder?   At this point I had a guess..   The file mentions “browser.resources” and also “8.0″.    Could this be Internet Explorer 8.0?   If so – it isn’t installed on the machine and could explain the error.

So..   Installed IE 8 and the patches then went on fine!





Inexpensive Virtualization and SANs

October 5th, 2009 admin

If you’ve never heard of a SAN (Storage Area Network) before, it’s probably because it’s been available only to enterprises with large budgets.

SANs are a way of providing disk based storage via network connections (usually fibre) rather than internally to the machine.   One of the advantages of this is that several machines can access the same “virtual” disk at the same time.   You may wonder why this would be useful as each machine would have a fast local disk anyway? 

Well, when you share a SAN volume, you can enable clustering which means that loads can be shared between machines, and this also provides redundancy should one of them die.

The latest use of SANs however is with the growing adoption of virtualization.   Products such as VMWare and Microsoft’s Hyper V allow many virtual machines (VMs) to run on one physical machine.   When connected to a SAN, it’s easy to move a VM from one physical server to another – and live with no disruption!

So, this brings me back to the cost of SANs.   Typically in the past – a SAN implementation would’ve cost many tens of thousands of dollars and was complex to set up.    This is still the case for large high performance SANs with fibre interconnect and multipath redundancy.

However Starwind have recently released a free version of their iSCSI for Windows.   This allows you to turn any 2TB windows server into an IP based SAN for free!    By using gigabit ethernet instead of fibre, it’s possible to create a Hyper V cluster using 3 machines (one being the SAN server) relatively cheaply.

Congratulations to Starwind on releasing such a product for free!   I can see this bringing live migration and redundant VMs to smaller businesses that previously couldn’t afford it.

I for one will be playing around with this further in our lab….
