APPV DSC and SCCM 2007, All together now !

September 9, 2013

Hello,

Recently had a strange issue in SCCM 2007 , APPV and DSC.

Situation :

One Virtual application with 2 mandatory dependencies , defined in OSD :



When running the adv for the APPV app we see the following :

1. Adv runs succesfully and the application registers succesfull in APPV



2. A reg key is created under the softgrid root for the packages that are referenced in OSD


3. in virtualapp.log we see 2 actions a add package and a publish package



Now we run the adv for one of the dependent packages and we see :

1. Adv runs successfully but no application is registered under APPV


2. The reg key for the specific ( dependant ) package is deleted under softgrid key


3. There’s only one action a publish and not an add of the package in virtualapp.log



How come ?

Apparently when running the adv the fact if a virtual app is registered in APPV cache is not checked in APPV itself but rather through the SCCM client registration ( notice that this is only the case for virtuall apps where DSC is used , “normal” virtual apps do not show this behavior )

When we delete the corresponding key in SCCM…


… and rerun the adv then the virtual app is added AND published and the DSC app will run.




Enjoy…

Application Virtualization Client : no network detected.

November 29, 2011

During a deployment at a client site we had some issues with a set of clients. In certain situations the APPV Client was unable to retrieve the virtual application from the SCCM distribution point.
The error message recieved was : A network connection was not detected.
Of course the client was properly connected and could ping the distribution point without any issues.


Now we only recieved this error on a particular set of clients, connected to a particalur Cisco switch so we suspected some network settings.
After playing around with the following settings :

-> Spanning Tree Protocol

-> EtherChannel negotiation

-> Trunking negotiation

-> Link speed/duplex negotiation between switch and workstation
We were unable to resolved the issue. We could reproduce the issue while performing the following actions :

-> Clear the APPV cache

-> Shutdown the workstation

-> Remove and reconnect the network cable

-> Start up the machine

-> Rerun the advertisement

-> Click the icon in order to launch a virtual app and …
The following appeared again :



We finally ended up opening a MS support call and the solution was fairly easy !
After the installation of the following hotfix the issue was resolved.
2517187 Hotfix Package 6 for Microsoft Application Virtualization 4.6 RTM: March 2011

“You try to perform a publishing refresh operation on the App-V client. However, the network is disconnected when you log on. Therefore, you receive a “0A-10000001″ error.”
Conclusion, always verify if you’re on the latest version of the software when you’re experiencing issues.
