Yesterday I was packaging an application called Kluwer Juridische Bibliotheek. When the user first starts this application a screen with the License Conditions pops up and it must be accepted:

KluwerEULA

I always try to remove such things as I don’t think it’s necessary for every user to accept it.

I usually change the text below the “This Computer” icon to reflect the current username and servername:

UserOnComputer

This is an ancient trick, just set the the LocalizedString Value of the following key:

to “%USERNAME% on %COMPUTERNAME%”.

It get’s a little more complicated if you want to set this from a script, because the environment variables are replaced with the actual value BEFORE they are entered in the Registry.

Citrix Web Interface starts very slowly

I remembered from a previous project that when the Citrix Web Interface this is caused by a setting called generatePublisherEvidence in the Aspnet.config file.

This behaviour has been documented by Citrix in CTX117273.

If you read it carefully you will see the note that you need to fix it in 2 places for an x64 system.

If you know me a little than you have probably guessed I wanted to fix this with a nice script. I have chooses PowerShell this time because it has good support for XML and I made a one-liner so I can easily use it in an Embedded Altiris script.

The script changes the config file for both x86 and x64:

EDIT: If you run by commandline you need to care of quotes within quotes, easiest thing to do is to use double quotes (“) to surround the commandline and use single quotes (‘) for Strings inside the commandline:

I needed to do a mass password change on imported accounts and decided to do this with Powershell. For some reason (maybe because I am using PowerShell 2.0) I got an unexpected error when using the Password property or the SetPassword method (RandomPassword is a function I wrote that generates Random passwords the meet the Complexity Requirements):

When you uninstall Exchange 2007 you need to remove all Mailbox- and Public Folder databases. If you try to remove the Public Folder Database this will fail because there are replicas of the system folders in the Public Folder database. I didn’t find a way to remove these replicas from the Exchange Management GUI but it can be done with the following Powershell Code:

Get-PublicFolder -Server <exchange server> “\” -Recurse -ResultSize:Unlimited | Remove-PublicFolder -Server <exchange server> -Recurse -ErrorAction:SilentlyContinue
Get-PublicFolder -Server <exchange server> “\Non_Ipm_Subtree” -Recurse -ResultSize:Unlimited | Remove-PublicFolder -Server <exchange server> -Recurse -ErrorAction:SilentlyContinue
Get-PublicFolder -Server <exchange server> “\Non_Ipm_Subtree” -Recurse -ResultSize:Unlimited | Remove-PublicFolder -Server <exchange server> -Recurse -ErrorAction:SilentlyContinue

(change <exchange server> to the name of your Exchange Server)
