Using special characters in Microsoft Deployment Tool (model name)

Currently we are working at a customer to set up a new environment.
To make this as easy as possible we are using the Microsoft Deployment Tool (MDT)

This will make it very easy to install computers with a new OS and the correct drivers.

However when the targeted computer uses the special characters like “/” in the WMI hostname, MDT runs into problems as the MDT workbench doesn’t allow special characters like “/”

The specified new name must not contain special characters

Microsoft App-V 5.0 SP1 Sequencer error while saving package

For a customer we’re creating a Windows 7 environment, using App-V 5.0 SP1 for application virtualization. We installed an English Windows with a Dutch MUI pack. All client types are installed unattended, including the App-V sequencer. We experienced a problem with the App-V sequencer which was caused by the MUI language pack.

Problem

After the installation of the new sequencer everything seemed to work fine. That is until I made the first package on the machine. The moment I clicked Save, an error popped up saying that the MSI couldn’t be generated. Read more

(Microsoft) Vendor specific DHCP options explained and demystified

DHCP servers can send vendor specific options to clients to granularly control configuration. Microsoft clients are out-of-the-box prepared to receive Microsoft Windows specific options while Microsoft DHCP servers have the ability to send DHCP options only received by Windows clients.

Some applications use the content of a DHCP option to receive configuration data, for example Microsoft Lync or RES Workspace Manager. Since this applications only run on Microsoft Windows its no more than logical to only send this option to Windows clients.

In this article I’ll explain how this mechanism works and how you can send Microsoft Windows specific DHCP options from a non-Microsoft DHCP server (like a Linux or Lucent-Alcatel VitalQIP appliance).

Citrix: Export to network drive really slow

For one of our customers I was asked to troubleshoot an application that exports data to several file types, including Microsoft Excel’s XLS file type.

Environment

The client runs Citrix XenApp 5 on Windows Server 2003 (x86). All user homedrives are mapped to the H-drive.

Problem

The application lets you perform queries on your Oracle database, analyze and format the results and prepare those for presentation. When the application exports an XLS-file to the H-drive, it freezes for 5 minutes and then responds normally again. However, when the same application exports a TXT- or CSV-file to the same drive, it freezes for just a few seconds.

Microsoft is calling: You're computer is having problems! (Phone scam)

Last week my wife got a call from from a person claiming to be working for Microsoft, and apparently they are receiving reports that there is something wrong with my computer! She told them that she does not need any help because she is married to an IT guy! But today I got the call and it seems it is the same guy because of his Indian accent!  Their phone number is blocked and the person is very pushy! But I thought lets play along!

“Microsoft Guy”: are you working on your computer now?
My answer :Yes.
“Microsoft Guy”: I can see you a running Windows now!
My answer:  Yes (but this is what I was running at the moment:)
