Hi, I have a few issues with Vista networking, and I was wondering if any of you could help me:First off, I have a laptop with vista ultimate 32, and a desktop with vista ultimate 64.The first problem is that I have network discovery turned on in both machines, but the 64 machine can't see the 32 machine. The laptop can easily find the desktop, but not the other way around.Also, in the desktop, when i try to share a file (on the 64 bit machine), I right click on a folder, say share, but then in the list of users, one user called "uuid:10000000-0000-0000-0200-0125A713F00" shows up as an option, but this doesn't show up in the 32 bit machine. what is this?Thanks a lot for any help.

I know this is an old post, but I will answer it for any similar future problems by people with Windows Vista or Windows 7, My responses will apply to both operating systems, but the exact names of the Windows or Control Panel apps might differ slighly, if I am remembering Vista correctly. The concept of both described resolutions should apply to both operating systems regardless... First, the easy answer concerning the odd user account... The account mention in the previous post, "uuid:10000000-0000-0000-0200-0125A713F00", appears to be an account used for Media Center Extenders, such as an Xbox 360, Slingbox, or other similar device that can play media stored on a Windows 7/Vista computer. I use an Xbox 360 for this purpose and I have an account that is identical to your account, except for the last few characters. If you have this account and you do use a media extender of some kind, then I would feel more than very confident that this is the purpose for this account. Second, here is my recommendation for the file sharing and network visibility problem... I would imagine that the problem with one computer seeing the other (and file sharing as well) will be due to Network Discovery and/or File Sharing being turned off for "Private" networks, on one of the computers thinks it is on a network that is not private. The affected computer could also believe that is is not connected to a Work or Home (Private, ergo more secure) network, which would also affect Network Discovery. If both computers connect to your local network in the same fashion (wired or wireless to a local network port, wireless access point, wireless router, etc.), then both computres should realize that they are on a "private" network. Windows Vista and Windows 7 both apply a different set of firewall rules for "home", "work", "public" or "Home and Work" together. If one of the computers thinks it is on a "public" network, it will receive a more restrictive set of firewall rules and other network settings (e. g. network discovery). To simply turn on network discovery (what is my first choice of possible causes I would check), see the steps below: Open the Network and Sharing Center applet in the Control Panel Click the Change advanced sharing settings in the list of links on the left margin of this window The following window will appear. Simply expand the appropriate network profile and "Turn on" network discovery and/or file sharing. Be sure to enable any other options that are appropriate for your network. The Home and Work profile hould be the network used by two computers local to each other in most Home and Work environments. If the Title of the profile does not display (current profile) appended to the end (e.g. "Home and Work (current profile)", then that computer has determined, for some reason, that the network connection it is using is not on a private home or work network. If the computer shows that it is connected to a "Public" network, I would recommend that you DO NOT TURN ON Network Discovery in this case, as that would open a dangerous hole in your Windows firewall security if steps are not taken to to further tailor some custom advanced firewall settings, which I will not discuss in this post as it is a whole other beast of its own. After checking your "Network Discovery" setting, be sure to check other other settings for your networks, and make sure things are turned on for Home and Work that you wish to share in a secure network, and be sure to turn off the things you do not want to allow or advertise when connected to a public or unsecured network. ...to Check whether your network connection type is "Home", "Work", or "Public" and how to set to a "Private" type (Home or Work) In Control Panel open the applet named Network and Sharing Center a similar window should appear Verify that your network type is net to "Home network" or "Work network". If this is set to "Public", then you can click the network type (see the red arrow in the previous graphic) and select either "Home" or "Work", whichever is appropriate. I would only do this if your computer is currently and truely connected to a "Private" network, and not a shared or public network such as a hotel, airport, some odd VPN connection, etc. I hope this helps someone. If this does not fix your problem, and would like to see if I might be able to help you using some more details information about your specific problem, feel free to reply to this post. Your reply post will generate an alert for me, and I will check out your problem and see what I can do as quickly as I am able to break away from family, work, etc. -TSF
