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.

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.

Problem:

Recently I was having issues installing the Hotfixes XA650W2K8R2X64001 and XA650W2K8R2X64002 for XenApp 6.5  I keep getting the error "Installation ended prematurely because of an error" and in the event log I would get the below;

Citrix Xen 6.5 should be out Q3 this year, possible by the end of August.

Rather than me repeating what is already all over the net I thought I would post a few links to sites with I think have some useful information on what is coming.

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.

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.

There are two possible solutions with Access Management Console

Problem:

I recently had an issue tring to get Citrix's Client Redirection Direction working, whenever certain users tried to double click on a file that should redirect to a server they received a message stating "Access is Denied". However if they opening the application and then when to File => and selected the file everything was fine.

Problem:

When a single computer trys to connect to a terminal server session or a Citrix application you recieve the message

In my case this message was generated on a laptop after the hard drive had been moved to a replacement laptop.

Solution:

The users cached terminal server license may have become currupt, the below goes though how to delete the machines license

Problem:

I have just had a strange problem, when an individual user  tried to launch any published application another server desktop session was initiated with the below message, resetting the users profiles etc made no difference.

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.

Step 1
Before starting I created a backup of my data store take a look at http://www.geekshangout.com/?q=node/32 for instructions

Step 2
I created a new database and user on the SQL server

Step 3
On one of the Citrix Servers I created a file DSN that pointed to my new SQL database
