Greetings, I have spent the day trying to work through this issue, but could use some help. I had a Vista64 host seeing a Vista32 host, working fine, sharing a printer and basically thrilled on how well Vista handled this networking (hardwire through the 4 port switch on the Linksys modem). Unfortunately, I needed to upgrade the wireless modem to a (WNDR3700: NetGear). After the swithout and installation, all the PC's can see the internet, but none can see each other? I also can not seem to ping the ip4 address of each computer, from the other. All the basics have been covered, (Same WORKGROUP, private network, no password, all other network options set to yes). After the router switch, the Vista 64 computer does refer to the local network at Network 3, and the Vista 32 compter as Network 2. I tried to rename the network to both "Network 2", but this did not seem to help. I am a pseudo computer literate, but a novice on Network issues. Any help would be appreciated. (I have the ipconfig \all output from both computers as attachments). Thanks in advance, Steve +-------------------------------------------------------------------+ |Filename: Vista 32 config.jpg | |Download: http://www.vistax64.com/attachment.php?attachmentid=18190| +-------------------------------------------------------------------+
Hi After Changing the Router the IP numbers probably changed to the one used by the New Router. Check all the Firewall to make sure that the New IPs are in the trusted Zone, and redo the Sharing. Make sure that the Software Firewall on each computer allows free local traffic. If you use 3rd party Firewall On, Vista/XP Native Firewall should be Off, and the active Firewall has to adjusted to your Network IP numbers on what is some time called the Trusted Zone (consult your 3rd Party Firewall instructions. General example, http://www.ezlan.net/faq#trusted Vista File and Printer Sharing- http://technet.microsoft.com/en-us/library/bb727037.aspx When done hard reboot all network computers and the Router.

Thanks Jack I believe you are on the right track and that there is some I visibility issue at some Vista level (Firewall? Windows defender?). I reviewed you sources and went down these paths already. I am _not using any other firewall product, other then what comes with VISTA. Th NetGear modem does have some basic firewall functions operating, but couldn't find any thing specific to excluding PC to PC communication. also made an attempt to input specific IP addresses on the Vist Systems, as you mentioned below for exclusion from blocking, but I coul not identify a vista firewall option to allow me to go down this path. I found an option that is similar to what you described in your thir party firewall description... (Windows Firewall -> change Settings - Exceptions -> Add port -> "Change Scope"), but the dialog box entr forces you to enter a port number first, before it will allow you t enter a specific TC/IP address. Not being a network guy, it may b common knowledge that windows uses port "x", but could not identif where I would gleen this information? Just to review for clarity 1) All the well documented solutions from MS and others have bee attempted... 2) I have went to turning off the firewall completely on both system and performing a cold reboot on everything but the clock on th microwave, with no success. Is it possible that some internal vista registry key is stuck at som value that is thwarting the connection? I also found a nice hidde feature "Windows Firewall with Advanced Security Settings",but this di not seem to allow any direct entry of IP address exceptions either Thanks again Jack and if anyone else has seen this interestin behaviour before and has a possible solution, I would be greatl appreciative Take Care, Stev
