I just purchased Vista Home Premium HP Desktop. I have a Netgear Wireless Router Hard Wired to Vista, and XP laptop is connected via wireless.
I am trying to share files between the two computers.
I am able to get out to the internet from both PCs.
1. I changed both computer workgroup names to Workgroup and download Link Layer Topology for XP laptop. 2. I can see the Laptop Computer on View Full Map from Network and Sharing Center on Vista, but I cannot connect and it is not listed when I click on Network icon. 3. I can also see the Vista Computer from My Network Places on XP Laptop, but when I click on the Computer Icon from View Workgroups it says "\\<name> is not accessible. You might not have permissions to use this network resource. Contact the administrator of this server to find out if you have access permissions. The network path was not found." 4. I went into the Sharing properties and enabled sharing for Everyone. Now, something interesting is that the "Share" button is grayed out and so I had to do this by clicking on Advanced Sharing. Does that sound right?
One of the guides said to make sure I set up matching users and passwords on both computers and connect that way. Another said leave it off.
I am stuck and this point. Need some next steps.

Morgan - You seem to be going down the same path as me. Last step, I had to go deep into McAfee and enable the range of home network IPs - they were discovered but not checked on, then the Vista and XPs all started to see each other and file share. If you have McAfee I can help more if you can't find it in there.

I am having a similar problem. I have a vista laptop and an xp desktop. I wanted to access files on xp from vista with password protection, and here's what I've found out.
I have "simple file sharing" disabled in XP, and instead have a user that matches the credentials on my vista box. I have all the users/groups settings correct in "computer management" and I have all the sharing/security settings correct for the folders I want to share. Correct in that the inheritance of privileges is such that remote access is configured ONLY for a certain user on my vista laptop. I have windows firewall running on both machines.
I had to do some wacky workaround to set Vista to be compatable with the network authentication protocol used in XP. It had to do with modifying a registry key so that vista used a different version of NTLM. I can't remember exactly, but search the forums and you will find it. Search for NTLMv2
Turns out you cannot share files in said manner. There are two workarounds, but neither permit one to eat and posses large amounts of cake simultaneously:
1. In XP on the folders you want to share, add the "everyone" group to list of allowed users and give them the permissions you want. Make sure the NTFS permission under the "security" tab are also configured for "everyone". This is unacceptable, because you don't want everybody to have access to your files.
2. In XP, you can disable windows firewall, and achieve the desired result. Drawback with this is you need a firewall. Potential workaround is to use a hardware firewall such as a router, but this can be a huge pain if you have http, ftp, mysql, and various other servers running.
Dear Microsoft, Judging by the forums, there are a lot of people who are having the same problems. I read a KB article that stated, "when a vista pc with logon credentials that are not part of the list of users specified in the security/sharing settings of the XP shared folder it is trying to access, the vista user will be prompted for username and password and permitted access if credentials match one of the users in the XP folder permitted users list." I was not able to provoke this behavior. I was never prompted for a password on my vista machine even after I did the NTLM fix. You should consider issuing a fix because XP is going to hang around for a long time, and people who get vista are going to want to access their XP files securely without having to use simple file sharing or giving "everybody" access.

It sounds to me like a third party fire wall software problem. On Nortons Internet Security it's the intrusion prevention. It's seperate from the fire wall, so even if you turn off firewall you still get the problem. You need to go to the intrusion prevention settings. An in the trusted tab enter each of the ip's for all of the pcs on your network.
If it's not Nortons or McAfee as tick stated, then post what software you are using and someone maybe able to tell you where you need to look to get it to allow access.

I have a similar problem. I have a Windows ME desktop with Norton Internet Security 2005 and a new Gateway MX8711 laptop with Vista Home Premium and it had a trial version of McAfee Internet Security installed. They connect through a Linksys WRT54GS Router. I can connect to the Internet from both. I can see the Vista Machine on the ME and vise versa. Neither can open the others files. I get the following message on the Vista Machine: \\PCNAME is not set up to establish a connection to port "File and printer sharing" with this computer. Both machines have the same user name and no passwords. I updated ME to use NTLM2. I was able to open ports 137-139, and 445 in McAfee. I have added a range to the trusted IPs. In NIS2005 I have added the IP range in the trusted IPs. How can I add trusted IPs to NIS 2005 Intrusion detection? Any help to resolve this problem would be appreciated. Thanks in advance.

Hi Cj9998,
I must admit over the years I've discovered it's better to have the same firewall software on each of the pc's on a network. As all software programmes do the same thing, but in a slightly differently way, so this can on occasions cause some hassel.
I'm not sure if 2005 had the option to enter trusted ip's or not, though I suspect not as 2006 didn't, so I down loaded there free upgrade to 2007 features. In 2007 i opened up settings for the fire wall/intrusion prevention, and there is a tab for trusted.
I've just checked Norton Internet Security 2005 for you on their website to see if there are any updates, and I'm sorry but it looks like you may need to upgrade to the newer version.
Some one on here (I think it was Trick) did explain how to add trusted ip's or turn on trusted ip's in McAfee. I'll have a quick scan through in a bit and if I find it i'll post the topic link ok.
But in the mean time I would (if it was me) down load another copy of the McAfee that you have on your new laptop, onto your desktop. By having the same sofeware it will cut down on the conflicts between them.
Ok found it, here's what Trick did in McAfee:

Rod - Turning on XP first then Vista was my solution until I found that in McAfee you can allow the ip range of addresses for the local network. Once I did that, the sequence doesn't matter. Think Norton is the same deal. Here's the McAfee path:
Right click on McAfee icon in system tray, open security center, internet & network, configure, firewall protection, advanced, trusted & banned IPs, add your home network range or click it on if it is there (it should be there, mine was but it was not clicked on) or add each ip range/address you want to allow.

You may need to give your (common) user accounts a password - I know some stuff requires the account have a password, but don't remember exactly what. Those of us who hang out in the Media Center newsgroup generally feel that Norton is much more trouble than it's worth, and should be removed at earliest opportunity...

Thanks Linda and Dana for your quick responses. Here is a weird one. I disconnected the Internet, shut down Norton completely and disabled McAfee Firewalls and still have the problem. Could file and printer sharing not be configured properly on Vista hence the \\PCNAME is not set up to establish a connection to port "File and printer sharing" with this computer message? I will add passwords to the logins to check it out.

You did enable file sharing in Network and Sharing didn't You? If not open Network from Start menu, then click on Network and Sharing in the Network window.
