I am having a huge problem with my pc connecting to the XBOX. I connect wired
via the PC. I have tried direct connection but this also fails, i can however
access (sometimes!) Media Center via the XBOX. The pc see's the XBOX but
describes it as an 'unknown network' and refuses to let me edit/make it a
private network and limits the connectivity or just gives it local access
only.

About two weeks ago suddenly the whole connection went and i was informed
that this was due to the MTU, after a while the message then changed to IP
connection failed. I am wondering if an update to the Windows Vista HP is
causing the problems. I actually freshly reinstalled Vista HP and the problem
is still there. I have no oither applications on the pc aside from what is on
vista, including no anti-virus or alternative firewall. I have reset the
ipconfig and gone through all the steps given on the XBOX support forum and
it has not helped at all.

In XP i had the two connections on a bridge (i think, i am not very
technical minded but i did see a connection called 1394(?) and the PC
alongside the XBOX connection), now i seem to have an internet gateway device
(Microsoft Network Infrastructure) with no explanation to what it is exactly
(!?) I can't seem to edit the properties and half the information appears to
be missing. The ip that is has is just :1. I haven't a clue to be hionest but
that just doesn't seem right.

Anyway, the information on the xbox error message points to something to do
with the DHCP - where can i find this to edit the properties? Would this have
anything to do with my ISP?

I really don't understand this - it was so much easier in XP!
