HomeGroup? Workgroup? How's this possible?

[LuckyOne]

Hello: My first post as a new member concerns a networking question.

I have a desktop machine at home running XP MCE 2005. It is connected to a Belkin My Essentials wireless router.

Two nights ago, I brought a friend's new Win 7 Home Premium laptop to my house, to mess around and explore Win 7 for the first time.

The laptop found my wireless network immediately. When it "asked," I selected Home as the network type.

I was then able to access my desktop's shared folders on the XP machine instantly.

My questions are:

1. How is that possible, since they have two DIFFERENT workgroup names? Or does the new HomeGroup feature override that somehow? (the Network and Sharing Center said I had joined a HomeGroup).

2. If it somehow did override those two different workgroup settings, how is THAT possible? With my LIMITED understanding of Win 7 and HomeGroup, I thought that HomeGroup only works with Win 7 machines, not machines with different O/S.

What am I missing here?

Thanks very much!!

What kind of sharing do you have enabled on your XP computer? Do you have simple file sharing enabled? Have you given the "everyone" group access?

Thanks for your reply! Yes and Yes, to the questions you asked.

I am interested in learning about Win 7 and why/how this "event" is even possible!? Everything I have read about 7 so far (and the LITTLE I know about networking) led me to think that computers in different workgroups could not access each other (and that HomeGroups ONLY work for networked Win 7 PCs)?

Not a huge issue - I just like to understand things : - )

Thanks again,

Lucky

P.S. heading out for a few hours......

AFAIK, if you give "everyone" access to files, you are opening things up to anyone that can get into your computer. Try this test - remove the everyone group and add the authenticated user group, then see if 7 has access.

The homegroup construct is only for Windows 7 computers. It is just a dumbed down version of a workgroup - I have no use for it, and I recommend using a workgroup instead.

Thanks again. With my limited understanding, I didn't think ANYONE could get to the shares unless they were part of the same workgroup. I'm not too concerned about the security, because I am the only one in the house using the network. I have my XP laptop set up to get to the desktop shares, but I was shocked when the new computer of the group (friend's borrowed Win 7 laptop) was able to "sneak" right in so easily....
