Windows Server 2003 does not include drivers for the Sound Blaster 16 emulated by Virtual PC (nor is this card officially supported in Windows Server 2003). It is – however – possible to get sound working by loading the Windows XP drivers under Windows Server 2003. To do this you will need to:
Copy the files wdma_ctl.inf and ctlsb16.sys from a Windows XP product CD to a folder.
In the Windows Server 2003 virtual machine, go to Device Manager –> Other Devices –> Sound Blaster 16 –> Update Driver:
Install from a list –> Don’t search –> Sound, video and game controllers
Have Disk –> Browse –> Select folder with the two XP files
Other requested files can be selected from the Windows Server 2003 product CD.
