In theory, nothing. Zeroconf is just a way to "announce" services available to the network, so it's another way to find the same SMB server. I have noticed that adding SMB servers via zeroconf will use the IP address, while using the SMB browser will use the NetBIOS name. That might be why one worked and the other didn't, but that would be kind of odd.
