How to Enable Security for the Event Notification Sample
By default, Windows Media Services runs under the Network Service account, a predefined local account that has minimum privileges on the local computer. Because the WMS SDK Sample Context plug-in can both read from and write to a log file, you must add Network Service to the folder access list and specify read and write access. The necessary steps are:
Create a folder in which the log file can be saved.
Right-click the folder and click Properties.
Click the Security tab.
Click Add.
Click Locations, click the top node identifying the local computer, and click OK.
Click Advanced.
Click Find Now.
On the list, click Network Service, click OK, and click OK again.
Make certain that both read and write access are enabled in the list of permissions that can be granted to the Network Service account.
