No access from XP to Vista

Hey Michael,

thanks for your anwser, stoll: I tried this already; did not work; both
machines same login, same password, both Admins. Anyways that would not be a
good solution as the plan is to have more computers in the network.

I have an XP PRO SP2 machine with a usb printer I share. I have 5 machines on my home network. My machine can see and access an XP Pro SP1 machine and that machine can see and access me. My Vista Home Premium laptop which is new can see both machines; can access the SP1 machine and the SP1 machine can access the public folder on the Vista machine. My XP Pro machine cannot see the Vista machine. Vista sees my XP Pro Machine but gives an error when trying to access it. The error code is 0x80070035, the network path was not found. The text message says Windows sent the request to the DNS server and the server responded that the name was unknown.

I have Comcast cable and all machines have Comcast provided McAfee Security Suite on each machine. The trusted IP range is in the range of all the machines. All my machines are MSHOME workgroup. Vista is set on a private network.

Clearly something is not right with my XP Pro machine but I have not been able to find anything remiss. I have elminated TCP/IP V6 as being the issue, Mcafee firewall was eliminated (turned off on both machines while disconnected from the cable modem. Windows Defender is off. I checked TCP/IP properties and both machines are set identically (auotmatically detection). All advanced settings are identical.

I have a 4 port switch/firewall uplinked to a 4 port router. DHCP is turned off in the router, the switch has DHCP turned on and assigns IP's to all the machines in the same range. 192.168.0.(2,3,4...255) My machine is an Nforce 2 motherboard. Nvidia Eithernet firewall is off.

I unistalled TCP/IP V6. I uninstalled SQL Server 2005 (on a whim since I don't use it anyway). I can ping the Vista machine all day and it responds without errors or delays. I can flush the DNS cache, repair the Eithernet network, run ipconfig /renew, release, /all...etc.

I have changed one thing. Rebooted both machines. Tested. Changed another thing. blah blah.. for 12 hours. I'm frustrated.

Have you checked firewall settings? If you have OneCare installed, you need to allow networking in OneCare firewall.

Hope this helps

I do not have One Care installed.
experiments I tried:
disconnected from internet, disabled both firewalls.
symtpoms remain the same.

I have a 4 port switch casscaded to a 4 port router to extend my network. I simplified and connected to just the switch and then just the router. Still no change to symptoms.

To be able to connect to another machine on my network running XP Pro SP1 I had to enable IPX/SPX/NetBios compatible protcols in network settings. I experiemented by unchecking and lost access. I rechecked the protocol and gained access again.

I downloaded and installed on both my XP machine and the Vista machine.

I used McAfee Security Suite on all my machines as it is provided free by Comcast (my cable internet provider) On every machine under, "Manage Network," every machine is seen with it's TCP/IP address. Every machine has trusted IP's in the range set by the router.

When I use, "Diagnose," on the Vista machine in the box that says it can't find my machine, the error message states that, "Windows sent the request to the DNS server and the server responded that the name was unknown."

I have a dual boot machine so I booted to Windows Vista RC1. In RCI both the Vista laptop and my machine could see and access the other machines on the network. When I rebooted both machines, the laptop still showed the connections but no longer could acess my machine. The laptop can access every machine but mine.

On my machine in Local Area Connection Properties I have the Link-layer Topology Discovery Responder checked on both machines. Vista also has Link-Layer Topology Discovery Mapper I/O driver checked.

I have read knowledge base articles. I have rebooted both my machines dozens and dozens of times, changing just one thing at a time. I am still stymied.
