I have a 4 computer network. 2 PC's running XP Pro and 2 Laptops running Vista. One Laptop cannot see any of the other computers on the network. The other laptop running Vista can see this Laptop running Vista and even access it, but the reverse is not the case. One of the XP PC's can see the Vista Laptop but when it tries to access it, an error message is displayed saying that the computer is not accessible and that there might not be permissions to allow access... I have tried everythign I can possible imagine to make this computer show and work properly on the network and I just can't figure out what to do. Please help.

Assuming you're running security software with a firewall, have you checked it to see if it's stopping incoming traffic? You may have to trust the IP you're trying to access from.

Here is a post with a problem similar to yours that I just found http://social.technet.microsoft.com/forums...6-d0f8b09603a4/

More specifically, this post in that topic should help you

I'm posting here the 5 major steps I went through to get my Vista-WinXP network running seamlessly. If you are having problems with yours, perhaps one or more of the below 5 steps will do the trick. Step 5 was the most obscure - changing a registry setting in one of my WinXP machines so that my Vista pc could see its shared folders.

Windows Networking – Vista and WinXP

Ok. First take a deep breath and gather your patience. I wrote-up the below thread after my recent experience in networking a new Vista laptop with two existing WinXP machines. It wasn't quick but it did work, eventually. Try some of these steps:

1) Firewall settings - one of the biggest hassles. To get started I suggest you FIRST disconnect your network from the internet (for your protection), then disable ALL firewalls (including Windows firewall) on ALL machines, and then work to get your home network operating internally. What I learned on my home network is below.

1.1) My WinXP machines have ZoneAlarm and I needed to ensure that all machines on the network were in the trusted zone. Go to the Zone tab of Firewall settings in ZoneAlarm free version. Ensure all of your machines’ IP addresses are listed, as well as that of your router or wireless access point.

1.2) My Vista laptop came loaded with Norton Internet Security. Go to Norton Internet Security tab, open settings, scroll to bottom, open internet security and firewall options, open advanced settings, open configure, change default inbound NetBIOS, inbound NetBIOS name, and Block Windows File Sharing to ALLOW. Configuring this beast of an app required a lot of trial, error and googling the Symantec site and others.

2) Ensure sharing is enabled on all machines. It is quite different for Vista vs WinXP. The procedure is fairly straightforward and is well documented on the MS site and elsewhere. In Network and Sharing Center it is critical on Vista machine that you have your network configured as Private and that the Sharing and Discovery Settings are set to ON except for Password Protected Sharing.

Link for WinXP: http://www.microsoft.com/downloads/details...;displaylang=en

3) Workgroup name. Ensure you are using the same workgroup name on all machines. WinXP and Vista machines have different default workgroup names.

WinXP: http://www.microsoft.com/resources/documen...e.mspx?mfr=true

Vista: http://windowshelp.microsoft.com/Windows/e...6fcead1033.mspx



4) Download and install Link Layer Topology Discovery (LLTD) onto the WinXP machines. Just a nicety, this enables the network map in Vista to show all machines on the network.


5) And the final step: check the registry on your WinXP machine per MS article 913628 that I found by searching MS for "error message when you try to access a Windows XP-based network computer: "You might not have permission to use this network resource". See the article at: http://support.microsoft.com/kb/913628. This finally did the trick for my network.

Keep pounding away at it. It will eventually be worth it. It took me almost a week to get everything working right.

Best of luck to you …
