I was able at least to share a file now and then and I did see my 'other' pc on the Win 7 netbook, but i could never actually ping either one of them. As i understand it, only home groups can see each other on a full time basis...maybe that is why i was able to share a limited amount of files now and then. I read somewhere that they both have to have the same domain name....ie home group. My desktop has work group and my netbook has home group. I tried to change the workgroup to homegroup, but couldn't. Lately i am trying to get my new win 7 netbook to see my xp desktop's Lexmark laser printer, and in doing so i lost my one connection to my desktop...now, and think i have to start from scratch again to get out of this quagmire...but don't even know how to start.
