When u have an application that starts from a networkshare and uses local files you could encounter the error “0xc0000142” after sequencing.
The application “Planbord” in this case has an App-V package that has several DLL-files and a link to a networkshare located executable. The Package works fine when y0u start it from the sequencer. After deployment on a Citrix server the following error occoured:

SCRN 12-sep 10.42 0000
In the App-V event log you will see this event error:

“The virtual application ‘\\xxxx.xxxx.lan\Apps$\xxxx\xxxxxxxx\Programs\planbord.exe’ could not be started because the App-V Subsystem ‘Virtual Shell’ could not be initialized. {error: 0x8DC02125-0x40”

This is because the machine where you are running your App-V package from has no rights on the networkshare. The App-V 5 virtual system needs these rights I presume.
Just give the computer account (for example all Citrix servers) read/list rights on the file share.

note: The same package in App-V 4 did not need these extra rights.

When provisioning a Citrix environment you can come across some problems with the McAfee Agent.  The agent generated a unique ID to communicatie with the ePolicy Orchestrator (ePO) server. As the same AgentGuid will be in the vDisk, the ePO server will see all provisioned servers as one.

While building a new Citrix XenApp 6.5 environment we got some weird messages in the Application Manager Logging. Every time someone logged in some random dll’s were blocked with names like t3j5irzu.dll.

I’ve used Process Monitor from the sysinternals suite to search which process was creating this dll’s. I’ve started process monitor as an administrator and logged on to the XenApp desktop with a test user.

Office Web Components 2003 (OWC) is antique. as you can see in the 2003 part. It isn’t supported anymore on the newer Windows versions OWC Page. There isn’t a upgrade for the software. When building a Citrix XenApp environment, there is always legacy software, like this.

OWC is simple software. It is a Internet Explorer add-on that shows excel reports. It contains a few files and some registry keys.. So I thought it would be something easy.  But it gave me a headache. I didn’t work at all. After some googling (Google knows almost everything if you use the right question), I found out that OWC doesn’t like UAC. So I disabled that in our vDisk (we use Citrix provisioning). Probably the reason that Microsoft doesn’t support it anymore.

I did work afterwards when I logged in as an administrator. It still didn’t work with my test user with restricted rights. I got the following error, this is the default error if OWC doesn’t work:

Safety settings on this machine prohibit accessing a data source on another domain
