Tips From the Field: Citrix Receiver (mobile) Connection Error

**UPDATE** This issue has been corrected as of Receiver 5.9 for iOS**

So I’ve been running into this problem now a few times over the past couple of weeks and wanted to get the word out. Apparently the timing is just right and people who put SSL certificates on their NetScaler Gateway, Secure Gateway, or CAG are hitting that refresh cycle and renewing their SSL certificates and a lot of times it appears that went well…UNTIL they test and realize their mobile devices can no longer connect and are getting a generic “Connection Error. Citrix Receiver could not establish connection with the remote host/server”. If this is you..then read on..

Tips From the Field: StoreFront 2.0 Users Cannot Contact Store

So ran across this one today.

IF you are using StoreFront 2.0 AND auto-subscribe apps to your users (KEYWORDS:Auto in description) AND you see an event ID of 5 in the Citrix Delivery Services log on one of your StoreFront servers that is failing and the description is “The auto provisioned app with id “FarmName.AppName” has not bee subscribed during the last enumeration.”

Supposedly it manifests around 700+ subscriptions, although I have seen it hit as low as the 500 mark. (Calculate by <users> x <subscribed apps per user>)

This is particularly nasty because it defeats your load balancing even if you have a properly setup NetScaler utilizing StoreFront monitors..it will keep sending connections to the effected server rendering you with a random and nasty bug.

To check if this might be your issue go to a StoreFront server that is presenting the Event ID 5 with the above text and open PowerShell, Set-ExecutionPolicy Unrestricted, change to C:\Program Files\Citrix\Receiver StoreFront\Scripts and run .\ImportModules.ps1. Once complete, run a store subscription export by running Export-DSSStoreSubscriptions -StoreName <store> -FilePath c:\blah\subscriptions.csv and then open that CSV and see how many lines you have. If its in the hundreds then you might be effected by this bug.

Open a Citrix Support case and reference SR 61125582 for the private hot fix. Word is this will be included in StoreFront 2.1.

Happy <bug> hunting

Tips From the Field: XenApp Pre-Launch and StoreFront 2.0

Unless you’ve been living under a rock for the past couple of years you know what Pre-Launch is in a Citrix XenApp environment. It was, in my opinion, probably one of the best advancements with XenApp in the last couple of releases because it made the largest perceivable impact to the end user..that being the appearance of getting them to their data and apps QUICKER! If you were like me, that was one thing you dearly missed when StoreFront 1.2 came along and we slowly began transitioning from deploying ole’ faithful Web Interface to the snazzy new StoreFront. Well, did you know that pre-launch is back? A lot of people who I speak to don’t realize that it’s finally made its way back with StoreFront 2.0 and you should definitely be implementing it post-haste. One word to the wise though, it doesn’t work with XenDesktop 7 (yet!)..only XenApp 6.5..sorry early adopters.
