I am attempting to share an Itunes Library using Itunes 9.0 Home Sharing feature. I am able to see the libraries on the wired LAN but not the wireless. I have both PC's on the same workgroup but the wireless subnet is a different IP address range. I am using a Sonicwall TZ180 router /firewall and the rules allow all traffic between the WLAN and LAN and vice-versa. I am also allowing Netbios broadcasts through as well. I can ping the Itunes PC from the wireless laptop and I can see shares on the same machine no problem. The itunes PC can also do the same. After running a Wireshark sniff I noticed there were a few errors that might be related. They are SMB and SMB2 errors for NTLMSSP challenge response. Any thoughts?
