Citrix XenApp Rolling Reboot Script

I want to share one of my recent finds, I have a Citrix farm that has users logged on 24/7 so scheduling a reboot is difficult. Luckily Dane Young over at itvce.com has created a rolling reboot script that does a great job.

Allowing Citrix Receiver 3.1 to use HTTP as well as HTTPS

Problem:

I have just upgraded Citrix Receiver from version 3.0 to 3.1 and I found it only allows connections to HTTPS addresses, currently I am working on test servers so adding a certificate seemed a bit over the top.

The account URL must use the https:// prefix. This prefix assures a secure connection

Citrix Access Gateway and iPad Receiver "Please Wait"

Problem:

Recently I have been tring to connect iPads to our Citrix Farm via a Citrix Access Gateway VPX and had a far bit of trouble.

I could connect fine from a Windows XP computer over the Internet using either the Online Plugin client or by going to the web page however when I tried on the iPad I got my list of available application but when I tried to open one I got a nice “Please Wait” whirly message and 20 seconds later I was bombed out back to the application list.

Citrix Online Plugin - Seamless Applications Not Working with Dual Screens

I have a dual screen computer and recently noticed that when using seamless applications with the Citrix Online Plugin I could not move the application to my second screen.

After a bit of digging I found this issue was related to a "graphics memory" setting for the Farm

By default Citrix limits the maximum memory for a sessions graphics to 4Mb however this is not large enough for a high resolution application on a dual screen setup.

I recently needed to migrate our Citrix data store from a MS Access database to Microsoft SQL Server 2005 (32-Bit), this document shows the steps I went though.
