WinDbg: Couldn’t load mismatched pdb for ntkrpamp.exe

Written by Ingmar Verheij on October 12th, 2012. Posted in Other

When using a  debugging tool (like WinDbg) the debugging tool needs symbol files to display and interpret data. The symbol files (.pdb – program database) are provided by the software vendor, it is not part of the debugging software.

If your system is connected to the internet providing the Microsoft symbol files is very easy, just provide the online symbol server of Microsoft (explained in KB311503).  In my case the system had no direct internet connection so I had to download the symbol files manually.

In this article I’ll explain how the .ICA file is constructed, what sections and properties are commonly used and how you can create the file.

Configure hostname via DHCP

Windows 8 - HostnameA system can be identified on a network with a MAC address, IP address or its hostname. The hostname is the most readable form for humans, especially because you have the ability to change the hostname (unlike a MAC address and only partially for an IP address).

Giving the device a human readable hostname makes it easier to troubleshoot issues and is sometimes required to to apply to a naming convention. Having an asset tag on the device makes it easier for a user to explain what device he/she is using.

But what if you’re unable to change the hostname of a device or don’t want to specify this for each device? Think of thin clients (or zero clients) like a HP Smart Zero Client where you can’t (or want) to configure the hostname per device.

Well, you can push the hostname via the Dynamic Host Configuration Protocol (DHCP).

Delayed browsing (5 sec) with redirected My Documents on Windows Server 2003

Written by Ingmar Verheij on July 19th, 2012. Posted in Other

When you’re opening a Windows dialog like “Open File” / “Save File” or browse in Windows Explorer with a redirected My Documents folder, you might encounter a delay between 3 ~5 seconds. This is issue applies to Microsoft Windows Server 2003 SP2 (and maybe more operating systems).

 

The problem can be reproduced by starting Notepad and opening the “Open File” dialog (File > Open). The dialog will show the My Documents folder, if you immediately click on the My Document folder (which is already opened) it will show a hourglass cursor for 3 ~ 5 seconds hourglass_cursor.
