Happy to help, but when I discussed the support ticket with the engineering team last week, their recommendation was to use the laptop's Bonjour name in the URL you enter into the WebDAV sync interface. That way the existing WebDAV sync code does all the heavy lifting without any need to reinvent the wheel on the Windows side.

Is that approach not feasible for some reason? I'm happy to take the info back to them, but more details will help me explain the situation.
