Ok first up sorry for posting on a topic that I imagine has come up before but none of the threads I've read have covered the issues that I'm experiencing.
Basically initially I tried the whole connect xbox to an xp laptop via an ethernet cable and bridge the connection method, if I do this then the xbox says it cannot obtain an ip address. The advice I read on this was based around either selectin g the wireless network and allowing other networks to connect to the internet through it (which there is no option to do if the bridge has been set up and it will not allow me to create the bridge if I tick this option in advance) the other one appeared to be from locating information from the run-cmd-ipconfig/all and puting it into the xbox mac adress manually but this did nothing to fix the error.
I found that if I just connected the ethernet cable and didnt bridge the connection then the xobx was able to get to the second stage in the test xbox live connection, but it then comes up with the error "DNS Server cannot resolve the names of the xbox live servers". The solutions I read for this revolved around either getting and entering dns figures manually one again through the run-cmd-ipconfig/all method but this doesn't work as I have no dns numbers listed in there at all . Someone also mentioned entering the default xbox dns numbers manually or something similar I can't remember the specifics.
Thanks in advance for any help.
