To edit the registry so that the Windows Media Unicast service or the
Windows Media Station service depends on the Web server
Start Registry Editor. In the Run menu, type regedt32 and click OK.
To update the Windows Media Unicast service, in Registry Editor,
use the tree view to navigate through the following path:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\nsunicast.
Or, to update the Windows Media Station service, in Registry
Editor, use the tree view to navigate through the following path:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\nsstation.
Double-click the key DependOnService.
The Multi-String Editor opens.
Type W3SVC at the end of the list of services.
W3SVC is the setting that makes Windows Media server
components dependent on Microsoft Internet Information Server (IIS).
Restart the computer.
Notes
You must set Windows Media component services to be dependent on the
Web service so that the Web service can bind to port 80. If you do not
set this dependency, then Windows Media server components might bind
to port 80 first, and the Web server will not function properly. These
steps are specific to using Windows Media Services with IIS 4.0 or later.
If you use Windows Media Services with a different Web server, check the
documentation for that server for instructions on setting dependencies.
Your ability to make changes to the registry by using Registry Editor
depends on your access permissions. Incorrectly editing the registry
can severely damage your system. Before making changes to the registry,
back up any valued data on the computer.
