Citrix Online Plugin 14

Hi All One of my more popular posts discusses the ability to extract Citrix Online Plugin 13 from Citrix Receiver 3.2.  Whilst doing some testing with Receiver 3.3 it was apparent that Citrix have included Citrix Online Plugin 14 with 3.3 onwards. Support Information from Receiver 3.3 <?xml version="1.0" encoding="UTF-8"?> <Diagnostic version="1.0">   <Receiver version="3.3.0.17207">     <Plugin>       <Name>Self-service Plug-in</Name>       <ID>{6245E940-DA64-4D98-ACBB-56CEEE42E684}</ID>       <Version>3.3.0.27839</Version>     </Plugin>     <Plugin>       <Name>Online Plug-in</Name>       <ID>{8C92B884-C818-45D0-A757-7123B78AA247}</ID>       <Version>14.0.0.1<...

IE9 hang......with no window?

Image
Hi there Recently we have had an issue with our published XenApp 6 desktop platform not performing very well.  We looked into the normal metrics and we saw the CPU usage on particular servers could be high. Initially we checked the process list and saw that iexplore.exe for one user would usually be the hungry process, taking lots of CPU.  This was originally associated with someone browsing to a site they shouldn't have.  The DFSS service which is on by default for Windows 2008 R2 RDS servers stopped this being a tragedy as other processes recevied CPU time when required, but there is only so far DFSS can go. Some information on DFSS http://blogs.msdn.com/b/rds/archive/2009/05/29/using-wsrm-to-control-rds-dynamic-fair-share-scheduling.aspx On further inspection (actually calling the user to understand their experience) it was clear that no process window was open at all and that the iexplore.exe process had simply hung.  Ending the process had no effec...

Citrix XenApp Load 100000

Image
Hi Recently we upgraded Citrix User Profile Manager on our XenApp server from 3.2 to 4.1.2.  After a reboot nobody could login correctly. I ran QFARM /LOAD and saw that the load was 10000.  Clearly this means the server is fully utilised.  The load evaluator in use reports full at either Memory 90%, CPU 90% or user load of 30.  None of these thresholds were being breached. I changed the load evaluator in Citrix to the default (user load =100) and then people could login again, but changing the load evaluator back to the custom defined one would make the load 10000. I logged onto the VM and tried to run performance monitor and got the following error message This proves that the Data Collector was unable to check the memory usage on the server and therefore set the load at the maximum of 10000. I open CMD as administrator and ran the following command on the server lodctr /R more information on this co...

Windows Security Update (KB2753842) Causes OTF Fonts To Disappear

Hello, I recently came across an issue where clients where experiencing missing fonts when viewing a PowerPoint project in presentation .  They could view the fonts correctly in editing mode no problem at all but when they went to presentation mode, they just disappeared. This problem doesn't happen when you're using TrueType Fonts at all, just OpenType Fonts and if you were to drop the font size down to 12 or below, the OTF fonts show correctly in presentation mode. The CAUSE is a Windows Security Update which addressed some security holes with OTF files.  There a quite a few WSUS servers which are set to install Security Updates by default, so I recommend you decline this update asap but only for client platforms as it's not likely you'll be using a client side app on a server. The RESOLUTION.  Well to remove the update in Add/Remove but in order to remove the update in a silent manor different commands are required for XP and Windows Vista/7 workstations. ...

Cubby - Storage sync

Hi I had a problem...........I use dropbox, I have about 6GB space after referrals etc.  I love the product, the fact it is multi platform and integrates so tightly.  The problem is space. Ok 6GB for free is great!  But my photos folder is 35GB and my music is around 32GB.  Sure I could cut these down in either quality or quantity, but I do not want to do that. I have an Asus Laptop, a Shuttle server and a Mac Mini (as media center) at home and keeping files in sync between each other would be good with Dropbox, but I don't want to spend lots of money for something that is an elaborate version of robocopy. Enter Cubby.  It is a tool currently in beta from LogMeIn.  The idea is pretty much identical to Dropbox but for a killer feature called DirectSync. This allows online computers to directly sync with one another, rather than going via the cloud.  Perfect for my scenario and I would imagine lots of other people.  As you can see in the s...

Wyse ThinsOS 7.1 resolutions

Image
Hi there! My company uses a large set of Wyse ThinOS terminals all the way from the old 1200LE to the new T10. The T10 is a cracking piece of kit, dual monitor in a tiny form factor which can also handle Citrix HDX and boot in seconds....it is pretty neat. For this reason we have been keen to replace some of the old 1200LEs and S10 devices with the T10.  Intially this was held up due to the session reliability issue I blogged about a while ago http://www.teamas.co.uk/2012/06/wyse-thinos-71-session-disconnecting.html This was fixed with hotfix 130 (7.1_130). The latest problem we had was with custom resolutions.  We use a WNOS.ini file to configure the terminals with a fairly basic configuration.  This will tell the terminals to use the DDC to determine the best resolution of which the monitor and device can handle. We then use a username.ini file when the user logs in, this will start the appropriate Citrix session for them.  This will also launch at th...

Lync 2010 Mobility Autodiscover

Image
Recently I have been configuring a Lync 2010 environment as a PoC for IM and presence for my company. The PoC includes using IM and presence from the desktop and on mobile devices.  This requires an edge configuration and reverse proxy using TMG 2010. I found the following blog post which is great for setting up mobility http://blog.schertz.name/2011/12/deploying-the-lync-2010-mobility-service/ Everything was configured included DNS names, certificates, software install etc.etc. Once I had everything configured I found that if I tried to connect using my iPad device it would provide the following error message. Can't connect to the server. It may be busy or temporarily unavailable. Please try again I looked at the logging and found that the Lyncdiscover URL wasn't being redirected to the configuration file required to login. Browsing to https://lyncdiscover.companyname.com would simply produce a error 403 forbidden message. I went to "more details" ...
