Very confusing Citrix XenApp problem

Guru · 2 Oct 2015 at 09:12

Hi all,

I've come across an issue which I can't quite get my head around.

We have a farm with 6 XenApp servers running Server 2008 R2.

All apart from one server are behaving themselves.

All of the servers have this folder:

C:\Program Files (x86)\Citrix\system32\

and in all of them there is an iexplore.exe

They all open IE, except for this one server... when you double click on iexplore.exe on this one server it opens chrome!

I can't get my head around this. I am not very good with XenApp and don't really know where to look to change this behaviour.

I've trauled through various registry keys on the servers and they are like for like from what I can see so I am wondering if there is some policy forcing this behaviour?

Short of scraping this server and building another I'm at a loss.

XenApp 6 btw.

Any advice would be awesome.

Cheers,

G

is the default browser set to chrome or something? Does it do this for all profiles?

Are all your servers not running on the same VDISK?

That would assume he is using PVS.

Is the iexplore.exe genuine or has someone copied chrome over the top?

At this point with massive lack of info we can assume anything

Haha IE is genuine, copied from another server just in case. I don't know about the VDISKS, will have to find out. I don't know this particular infrastructure well yet and I barely know XenApp at all if I'm honest. Only client we have who uses it afaik.

If you open Task Manager does IE appear in there?

No mate just Chrome.

It's so odd! I wish I knew XenApp better

Looking at the properties for the iexplore.exe files in C:\Program Files (x86)\Citrix\system32\ on two different servers the files are both identical.

Both say "Citrix Metaframe Server FTA" on the description

Both say "Citrix XenApp" under Product name.

Both dated 11 March 2010 00:09:52

Both 34.632 bytes

Both the same digital signatures.

I can't get my head round how one can open IE and one can open Chrome lol

My question though is, why are you using this file to launch IE?

IE is found in the following location:

C:\Program Files (x86)\Internet Explorer\

The .exe is 624kb meanwhile the one in the Citrix\System32 folder is 24kb (on my farm anyway which is XenApp 4.5... don't get me started).

I know this doesn't answer the question as to why this launches Chrome but approaching the question from a different angle.

ubern00b · 8 Oct 2015 at 13:58

Did some more research on this and that iexplore.exe in system32 is what Citrix uses for Content Redirection.

As someone said earlier, is Chrome set as the default browser? What is the actual problem you have, regardless of this exe opening Chrome? Do you have an issue with published applications that you have narrowed to this server?

More information please

Look in your Citrix Management Console and see how it's deployed to that server. IE isn't just magically there, it will only appear as a hosted application or be present on a Xenapp virtual desktop if it's configured to be.
