An invaluable source of Clustering, Virtualization, Tools, Scripts and Knowledge Base for Network Administrators Worldwide

If you set the advertisement to “Stream virtual applications from distribution point” then it would fail, but if you set the advertisement to “Download content from distribution point and run locally” then everything worked just fine.  When the application failed it would generate a 0A-400000C8 error similar to the one below:

An application on a Microsoft Application Virtualization (App-V) client may fail to launch with the following error:

The Application Virtualization Client could not launch application name.
The specified Application Virtualization Server could not be accessed.
Try again in a few minutes. If the problem persists, report the following error code to your System Administrator.

Error Code: xxxxxxx-xxxxxx0A-10000002

Madelinde Walraven created an article that covers many questions about App-V with HTTP.  This article describes the process and the underlying theory of this deployment method. From an App-V point of view, this deployment method is not too complicated, but there are some aspects that have the potential to cause confusion in the community. Add a comment

I’ll cover: configuring SPF settings, recommend connection settings, increasing security, creating some basic policy rules. I'll discuss additional settings to prevent spam and report false positives and false negatives.

We recently uncovered this issue and while we're going to be publishing a Knowledge Base article on it very soon I thought it might be helpful to mention it here as well.

Our very own Steve Bucci recently posted this great video that shows you how to collect the logs and information from your App-V environment. With almost any App-V support call we will ask you for this information but knowing where to find these logs will prove invaluable when troubleshooting any issue you might run into.

We also have some additional information on the App-V log files here:

Brien M. Posey: In the first part of this article series, I talked about the roles of the physical network adapter and the virtual network adapter within a Hyper-V parent partition. I also briefly discussed the virtual switch. In this article, I want to continue the discussion by talking about the role of the virtual switch in more detail. As I do, I will also show you how child partitions fit into the picture.
