Please allow me to welcome you to Windows Seven Forums! Your questions are welcome and we will try our best to help! Thank you for filling in some of your system specs, we all really appreciate you for that.

There have been several threads recently dealing with the new "HomeGroup" versus the "Workgroup" used in 2000, XP, and Vista. Rather than repeat all of that, here are a couple of links for you to check out. Then if you have additional questions, please feel free to post them back here.

Only Windows 7 computers can use the HomeGroup. Two computers need to be joined in only one HomeGroup, see the threads.

win xp cannot see win 7 on network places

Sharing permissions problem

Can't get laptop and netbook linked via Homegroup

Happy surfing!

Thanks Robert I have read the articles but none talk about why my media center is working over the network but none of the computers show up on the network.See were I'm coming from.Thats whats driving me crazy.

win 7 x64 wireless to xp pro wired

have set up static ip adress across network

IP's ping, no names recognition.

have have the netwwork up and running, shared, etc. Turn off Win machine and the next day no recognition. the whole problem revolves around names resolution
( I have pinged names and recieved 2 pkts back---weird--others timed out)

It has worked fine with router as DNS address it's all names res problems
