[Spice-devel] Webdav on Windows XP

The purpose of spice-webdavd is to provide the port to be able to use
webdav from the guest. If another program is able to use it I would
try to understand why Windows cannot.

Just to confirm, using netstat in the guest can you see the port (9843)
in listening state?
Is the Windows XP service running?

I would avoid it, Microsoft stopped supporting XP more than 6 years
ago. Windows XP is abandonware.
