We've just installed a second App-V Management server and setup NLB and DFS sharing of the content folder for resilience. Things were working perfectly to begin with but I've just noticed that for some bizarre reason some of the packages have been deleted from the content share on our original App-V server. Thankfully they all seem to be still intact on the new server we've built but If I try and copy one of the missing packages from the second server back to the original, it gets deleted by DFS immediately.

I get the following message in the DFS logs:

The DFS Replication service detected that a file was changed on multiple servers. A conflict resolution algorithm was used to determine the winning file. The losing file was moved to the Conflict and Deleted folder.

Additional Information:

Original File Path: E:\App-V\App Virt Management Server\content\7ZIP.100

New Name in Conflict Folder: 7ZIP-{67534C81-1D16-47DA-87B2-24D281B9C145}-v268403.100

Replicated Folder Root: E:\App-V\App Virt Management Server\content

File ID: {67534C81-1D16-47DA-87B2-24D281B9C145}-v268403

Replicated Folder Name: content

Replicated Folder ID: 7F718F60-C560-4E39-817D-0A2A07E16263

Replication Group Name: AppV

Replication Group ID: C02D9F3C-703F-4D81-AFFB-3C5ABD6CB23D

Member ID: 39CDEE63-86E9-4CF9-9BD3-6F881ADBD05F

Now I appreciate this is possibly just a DFS issue but wasn't sure if it was specific to App-V and the makeup of the content share. I've no experience of DFS and my colleague who setup the DFS replication seems pretty stumped by it. I wondered if anyone had seen anything similar using DFS replication for their content share?

Thanks in advance

Before you install VMware View 5, learn how to get the most out of VDI

Posted: 16 Jan 2013 10:40 AM PST

VMware View 5 includes some underused desktop virtualization features. If you're installing VMware View 5, take the time to learn what it can do.

Is a publishing and/or management server required in a production environment?

Posted: 16 Jan 2013 12:37 PM PST

I have the following scenario: In my test environment I have APP-V version 5

- I have a share with packages.

- With a grouppolicy I have set the client to use shared content store.

- With powershell I am distributing the packages.

- When a user starts the application the package is streamed.

My question is: Is this a supported configuration? (because I do not use a management or a publishing server)

The reason is that I want to use RES Workspace Manager with powershell scripts to publish the applications.

How to ensure VDI network connectivity, security

A virtual desktop isn't worth a nickel if a user can't connect to it. Keep your VDI network strong with traffic prioritization and security policies.

KB: HTTP Error 500.19 - Internal Server Error when launching the App-V Management Console

Posted: 16 Jan 2013 11:46 AM PST

Here's a new KB article we published today. This one describes an error you'll get when trying to use an App-V Management Console that's been installed to a drive other than the C drive. If you want to do this you'll need to add the appropriate permissions for the alternate install location and you can get all the details here:

Paper: Project Virtual Reality Check Phase V

Posted: 16 Jan 2013 12:38 PM PST

Sven Huisman, technical consultant at PQR, Dennis Geerlings, Consultant at Login VSI, Jeroen van de Kamp, Enterprise Architect and CTO at Login Consultants and Ruben Spruijt, Technology Officer at PQR just announced a new paper titled: Project VRC: Phase V Antivirus impact and best practices on VDI. The paper which contains 80 pages gives some valuable insight on the impact of using Antivirus solutions in a Virtual Desktop Infrastructure (VDI) environment.

The tests were conducted using the following products: Microsoft System Center Endpoint Protection (ForeFront), McAfee Enterprise, Move Multiplatform, Move Agentless and Symantec Endpoint protection.

The paper answers the following questions:

What is the performance/capacity impact of the most well-known AV solutions when used in a VDI environment?
How do AV solutions designed for virtual environments with so called "off-loading" architectures compare with conventional solutions from a performance perspective?
How does the disk IO impact compare with the different AV solutions, conventional and off-loading architectures?
What is the performance impact in stateless desktop environments in comparison to stateful desktops?
What possibilities are there for performance tuning and how does this affect the overall impact on performance impact?

Testing AV solutions proved to be more complex and more unpredictable than originally expected. It became very clear that most AV solutions were designed for typical Desktop and Laptop environments, not for (stateless) hosted virtual desktop environments. There is an important lesson to be learned here: the impact of antivirus is considerable, and it's vitally important to review and test this before rolling out an AV solution in a VDI environment. This is confirmed in the large majority of real-world VDI deployments, time and again.

When comparing various AV solutions, the conventional Microsoft System Center EndPoint Protection (SCEP) previously known as Forefront, seems to have the least performance impact, but only after performing a full pre-scan of the master image before deployment of the desktop VM's. This is a huge difference to ForeFront tests done without pre-scan of the master image (in those tests, without pre-scan, the performance impact was dramatically high).
