SVCHOST*32 AppEve running on port 21 with no ftp installed W2k3 x6

This is very strange.

I'm running x64 Windows server 2003, all svchost services run in native 64
bit mode, the other day my ftp server (not the windows ftp server) couldn't
bind to port 21. I did some research and found that the AppEve service was
running in 32 bit mode and using port 21. I can't just stop this service as
it is tied to other services. How do I reset this service to default
settings, or change the port number that this service listens on. Can anyone
shed some light on this topic? I can't find anything anywhere this.

Thanks!
