Here is my situation.
I am running a Windows XP SP2 machine- Attempting to get my brand new xbox 360 to "media share".
My home network is set up as follows:
Charter high speed internet (ISP)
NETGEAR FS105 (Hub/Switch)
The Pc and Xbox BOTH have internet connectivity through the switch, however, I am consistantly "failing" the PC test during the media connect on the 360.
Also-- my WMP11 Does not "see" the 360 in the media share tab.
I have tried almost every suggestion i have seen.
I even did a fresh FORMAT of my CPU today incase I had some weird old firewall running... but same results.
I have .NET 2.0 installed-- and as far as I can tell, all of my settings and connections are valid and work just fine.
My only other nagging suspicion has to do with the MAC addresses of my PC/Xbox.
Charter high speed registers your CPU's MAC address and then only lets IT connect to the internet, so I had to put my PC's MAC address into the alternate MAC address panel on my 360-- I have no idea if that would change anything in this instance, but I thought it was worth mentioning.
I am getting very frustrated by this whole process--- my switch allows both the PC and XBOX internet connectivity-- but I cannot for the LIFE of me get them to "see" and share with each other!!
