Currently at work I have a workstation with Windows Server 2003 R2 with SP2 and I cannot play WMV files. No, I wouldn't be slacking, we have internal webcasts that I need to view.
The Windows Media Player (version 10.00.00.3998) refuses to play the file stating
An audio codec is needed to play this file. To determine if this codec is available to download from the Web, click Web Help.
I go there and I am told that the audio codec is found. Great. After a few direct links I arrive at a download page where I download the codec and install it. After the successfull install I am required to restart the computer.
Later trying to playback the file the same thing happens as in the beginning of this question.
