Not sure about your streaming media query, but for your access denied query try:
Go to Start; Search. Click on All Files and Folders and then search for DSLMON.
The search should find a shortcut called DSLMON which is the shortcut to start your ADSL modem.
That shortcut should be in C:Documents and Settings\All Users\Start Menu\Programs\Start Up.
If it's not move it there/.
