Hi, Mike -

From what little I've learned about mDNS so far, it appears that sending a UDP broadcast to port 5353 using Windows Sockets might be the way to go. Unfortunately, I know next to nothing about using WinSock, but I do know that Roland has a WinSock free code sample on the TopWizProgramming web site that can utilize the UDP protocol:

Here is a URL I found to be informative regarding this subject:

HTH, John
