Heh! Memories! RM Networks ~1998/1999 when I was in School... You would login and then you got their interface popup saying you were over your space allowance and clear files or you can't login...
I did this exact same trick (passed network login though) to get out of it! Although, mine was to go to c:\windows, type . then right click explorer.exe and click open!
