Xbox Music Mixer PC transfer issue solved

**Cookie Monster** · 18 Feb 2004, 01:37 AM

I was browsing www.xbox.com this evening and decided to head over to the Music Mixer forums to see if anyone had gotten the @$#(%& PC Transfer tool to work consistently (or at all in my case). Lo and behold, someone discovered what the issue was. See below:

The XBOX sends out a network broadcast (message to entire subnet) on udp port 3074. If the Music Mixer PC Tool is waiting for a connection, it will reply back by sending a network broadcast on udp port 3074 which lets the XBOX know what IP address the XP machine is using.

The IP packet size that it sends 1353 bytes long. According to my sniffer, the packet my XP machine was sending back was being fragmented. After further investigation, I determined that the MTU setting on my network card was set to 1300 bytes. I don't know why or how it was changed, but I went into the registry and changed it back to the Ethernet standard of 1500 bytes. The interface has to be disabled and re-enabled (or a reboot) to use the new MTU setting. I ran the Music Mixer PC Tool, and it worked!

There is plenty of information on the Internet about changing the MTU, so I'm not going to go into detail here, but here are a few links that may be helpful.

Location in registry...
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet00X\Services\Tcpip\Parameters\Interfaces\{XXXXXXX X-XXXX-XXXX-XXXX-XXXXXXXXXXXX}
DWORD VALUE = MTU
Value Data = 1500 (Decimal) - You may want to set this to somewhere between 1400 to 1480 if you have DSL.

If you try this, and it works for you, please post a reply to this thread.

Good luck!

This worked flawlessly for me, and I have NEVER gotten the PC Transfer tool to work with any method. So fellow MM owners, take heart!

I've never had any problem with mine. I just made sure my Windows firewall was disabled and that was it. A lot of people I've spoken too were having a heck of a time getting it to work though. I guess I was just lucky.
