Thanks for the info.  The error level idea works great.  Here's the
batch file in case any other Windows users are interested and searching
for a solution.

****************************
@for /F "tokens=1 delims=- " %%A in ('Date /t') do set DD=%%A
@for /F "tokens=2 delims=- " %%B in ('Date /t') do set MM=%%B
@for /F "tokens=3 delims=- " %%C in ('Date /t') do set YY=%%C
set ST=1
:wget
ping -n %ST% 127.0.0.1 > NUL 2>&1
set ST=300
wget http://query-origin.andohs.net/8000A6/content-root3.andomedia.com

/origin/mp3/espnradio/insider/mikeandmike/mikeandmike_%MM%%DD%20%YY%.mp3
if NOT ERRORLEVEL 1 (sndrec32 /play /close "C:\Windows\Media\Notify.wav")
     ELSE goto :wget
*******************************
notes: indents indicate continuation of a line, ST=300 provides a 300
second delay by pinging the local host after the first failure and loop
back to :wget
