SoftICE crashing on Windows 2003

It seems like I'm a bit too stupid to use LiveKD. I did the following:

• Download and install the Windows 32-bit debugging tools
• Download LiveKD and copy it into the debugging tools folder.
• Configure the symbol path in WinDBG.
• Start LiveKD by running File->Kernel Debug->Local
• Open register, memory and disassembly windows from the menu

Then I had a command line (perfix: "lkd>") where I could enter my commands. I called "?" to list me the available commands

First I tried to show what's located at "fs:[124]" by entering "d fs:124", but I only got the message "GetContextState failed, 0x80004001" three times followed by "bad segment error at '124'.

Next I only entered "d 124" and got a memory dump, but only filled with "??" as data.

After that I read the help file entry for the "d" command to learn all possible "dump" commands and their correct syntax, but none of them worked, even the dump commands for psysical memory failed.

So how should I read "fs:[124]" from Ring-0 with WinDBG?
