According to the documentation for Mac OS X Snow Leopard you can using a Windows host's (or another Mac) DVD drive to remote install the OS again.
Turns out the documentation is not for Mac OS X Server but only the non-server edition. You can't use a Windows host to remote install the Server edition of Snow Leopard as the DVD contains no Windows files on it (I looked at it with ISOBuster to make sure).
I called Apple Enterprise support about this. Your best bet is to get a USB/Firewire DVD drive or use another Mac instead. Another option might be to boot from an 8GB+ USB thumb drive, but I haven't tried it.
