Céad Mile Fáilte…

That’s Irish for welcome btw – Well, it actually means a hundred thousand welcomes but that’s just how the Irish roll

Get to the point already I hear you say.. ok ok, just wanted to share a couple of observations on the funky new welcome screen that you get with XD5 (one of the new featuers of the new VDA v5). See below:

1. It is enabled by default but can be disabled by Group Policy if desired:

-User Configuration\Administrative Templates\System\Don’t run specified Windows applications (WelcomeScreen.exe)
-WelcomeScreen.ADM (available from XD Forums)

2. You can play with it and have lots of fun…

Just browse to the %SystemRoot%\Program Files\Citrix\ICAService\Content dir on your VDA and go for it!!!

Heres one I made earlier…

Profile Streaming is a great new feature introduced with Profile management (Pm) v3 so lets take a look at the performance gain the old fashioned way…

Using the following upm managed profiles lets use perfmon to get an idea of load times.

upm100mb (standard upm profile)
upmstream100mb (streamed upm profile)

First, lets log onto a managed W2K3 server with the standard “upm100mb” profile. Using perfmon & the Pm logon duration counter we can see that a 100MB profile takes around 5 seconds to load. Not bad I hear you say?

Now, lets follow suit but this time lets log on with the streamed “upmstreamed100mb” profile.

hmm, .5 seconds.

I’m sure you’ll agree – the results are impressive.

In my last blog entry Profile Streaming – Performance Gain? we looked at the performance increase when using the new profile streaming feature that ships with Profile management (Pm) v3.

We know it works because we tracked the logon time using perfmon but curious minds might ask the following question:

“ok,so how do I know this streaming profile stuff is actually working?”

well luckily enough – there is. 3 ways in fact!

1.The quickist and easiest way to do this is to look at the properties of the user profile. In the example below you will notice the size of the profile is >100MB but the size on disk is <7MB.

2.You can also use the dir /al command to list all files with reparse point attributes (Remember, the key to our profile streaming/fetch on demand design is the use of reparse points on files. Reparse points fool applications and users alike into thinking that the files are downloaded as part of the user profile at logon).

the screenshot below shows the L swith listed when running dir /? from a win7 machine. This is a hidden switch on XP, W2K3 but the functionality still exists.

Bottom line, If profile streaming is disabled, running dir /al on a folder containing files within the user profile, will return “file not found”.

3.Finally, you can confirm profile streaming is enabled for a particular user by reviewing the Pm log file (If enabled). To verify that the profile is being streamed look for the following:

2010-03-16;20:17:30.401;INFORMATION;<domain name>;<user name>;2;2364;ProcessLogon: User logging on with Streamed Profile support enabled.

You convinced yet?
