P2P Lan

miniB · 2003/05/24

Hi

I would be grateful for some advice on P2P.

I have a friend who uses this but was concerned about things. We disabled SSDP in services to see if he could still access the web etc & he can ! I do not know anything about this set up but he was convinced if this service was diasbled he would not be able to access the web. something about Lan & P2P...... but am utterly confused now

I would like to be able to find an answer to explain the reason but do not know enough about P2P & Lan things.

Hopefully someone can explain to me - are P2P & Lan the same thing ? Thank you in advance.

P2P is a variety of LAN. To save my fingers, I took the following from Here

LAN stands for Local Area Network. These networks can consist of anywhere from two to thousands of computers. Even a simple network of one computer connected to one printer can be considered a LAN. You can also get more in-depth information and view illustrations in the Reference Library article Understanding LANs.

Peer-to-Peer - Sometimes called P2P, these networks are the simplest and least expensive networks to set up. P2P networks are simple in the sense that the computers are connected directly to each other and share the same level of access on the network, hence the name. Computer 1 will connect directly to Computer 2 and will share all files with the appropriate security or sharing rights. If many computers are connected a hub may be used to connect all these computers and/or devices.

and there is more there if you want to read the whole thing.

This can become an issue if there are NT systems on the LAN (NT4/2K/XP) since a peer LAN doesn't offer them any way to authenticate PCs trying to connect to their resources. And without authenticating a user, NT won't allow access.

That's what gives rise to the suggestions you see often on here for each PC to require logon and have both a username and password. You then put each username/password into the local users section of each NT PC and that takes care of authentication. Or if security isn't an issue at all, you can enable the guest account on the NT systems and they will accept any logon/password combination - but there still has to be one so 9X/ME PCs have to require logon. For the truly lazy, you can get the same effect if every PC is using the exact same username/password.

Hi Newt

Thank you for taking the time to explain this to me. I am really so unsure about all this but now have a little more clarity - thanks to you & your searching plus the added extra

I have been watching all the posts about networking / Lan etc & TRYING to understand

I will take time tomorrow ( just going offline for tonight ) to read your post again & hopefully learn enough to be able to explain more to my friend

Thanks again Some day ...... I will manage to network myself & understand what I am doing
