If I run your code, GetLastError returns "The system cannot find the file
specified".

You appear to be assuming that the list of sounds in the Control Panel
Sounds applet corresponds to the list of names that will work with
SND_ALIAS. Not so.

Under XP (and I assume it is the same under Win2000), there is a list of
aliases under

HKEY_CURRENT_USER\AppEvents\EventLabels

One of the keys is called SystemStart. Under that key is listed the name
"Start Windows". You need to use the name of the key itself rather than the
string stored under the key. Thus

PlaySound("SystemStart", NULL, SND_ALIAS | SND_ASYNC);

should work.
