The “Bonjour Print Services for Windows” packages installed Apple’s Bonjour Service. Just thought refreshing the Bonjour Service within Windows might solve a mDNS problem, if it exists and if it might be broken/corrupt
I have, recently, for some reason encountered a few Windows installations where the operating has stopped resolving domain names to IP addresses. So far I’ve not found out why. Performing a system restore to a point before the problem appears seems to work.
