    I just built a new Vista PC. I was able to access and even see in network panel my win2k pc from the new pc. However in the beginning I could access and see it then after a time it would disappear and even attempting to map the drives would fail with an error saying it was no longer available despite the pc still being on and nothing having changed between the two. I could access and can still access the new pc from the win2k pc flawlessly at any given time no matter how long between times attempting to access. The problem connecting to the win2k pc from the new pc has degraded and now I can't access the old pc at all nore even see it in network panel even when both were freshly powered up. Attempts to access the pc manyually by typing the name of the old pc in the location text box "\\nameofpc\" i get a popup saying windows cannot access \\nameofpc\ etc and has a diagnose and cancel button. Pressing diagnose results in windows found an error that can't be fixed automatically. However I was able to access the win2k pc for a few days when it 1st no longer would show up in the network panel by using this method. I haven't done anything to change either pc since when it worked for the most part to now where it doesn't work at all. I am still able to flawlessly access the new pc with the win2k pc but not access the win2k pc with the new one.

    Can you ping the Windows 2k PC from the Vista by IP address? By name?

    Do you have a firewall on the 2k PC?

    Yes I can ping the pc by name and by ip and yes the win2k pc has a firewall kerio personal firewall and it was active when it worked and I even tried turning it off when it began to not work to see if it was somehow interfering but I still can't access it when the firewall is off when it doesn't work but since starting this thread there has not been an instance of it connecting correctly.

    Even though pings work my top suspicion is the firewall. Often they have to be properly configured or uninstalled. Sometimes they seem to get misconfigured during an update or a Windows update. Sometimes 'turn off' or 'disable' will suffice.

    The following is for XP, but think that Win 2k will be similar if not exactly the same.

    Make sure the following services are running (Control Panel - Administrative Tools - Services). The Startup Type on my machine is 'Automatic' except for the one indicated.

    Computer Browser
    DHCP Client
    DNS Client
    Network Location Awareness (Startup Type 'Manual')
    Remote Procedure Call (RPC)
    Server
    TCP/IP NetBIOS Helper
    Workstation

    I don't see this listed in services.

    There is also a Remote Procedure Call (RPC) Locater and it is set to manual. Should it be set to automatic as well?

    Everything else listed is and was already started and set to automatic.

    Remote Procedure Call (RPC) Locater set to manual is fine. If Network Location Awareness is not a Win 2k service, don't worry about it. I'm not positive what it does in XP.

    Is it possible that the vista firewall is causing the viewage of the win2k pc problem but not the reverse from the win2k to the vista pc? I know I shut off the firewall on the win2k pc and it doesn't make a difference. For a brief time yesturday out of the blue I was able to access the win2k pc from the vista pc but when I went to try again today it was back to the same errors as before.

    Can you ping by name both ways? Are ALL firewalls on both ends disabled or uninstalled?

    Turn off any firewalls for debugging. If the firewall is the problem, you'll have to configure it to allow access to "trusted zone" addresses. Note that some firewalls must be completely uninstalled to stop them from affecting your networking.

    Hold the Windows key and press R, then type CMD to open a command prompt for the following commands:

    PING each remote computer by IP address, and if successful, PING by name. Open a command prompt as described above and type.

    PING <ip address>
    or
    PING <computer name>

    Where:
    <ip address> - is the x.x.x.x IP address
    <computer name> - is the computer name

    A failure to PING is almost always a firewall configuration issue. Any failure to PING needs to be corrected before you go any farther.

    Note: You can obtain the IP address and computer name of a computer by opening a command prompt (DOS window) and typing IPCONFIG /ALL. This should work for any Windows version. The IPCONFIG /ALL display will provide a wealth of useful information for debugging your network connection.




    Let's see this from each computer.


    Hold the Windows key and press R, then type CMD to open a command prompt:

    Type the following two commands, one at a time, followed by the Enter key:

    NBTSTAT -n

    IPCONFIG /ALL

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

    Yes, I think it is possible for a 3rd party firewall on the Vista to be the culprit. More likely on the other PC.

    You've reported success with the pings, but the first and last sections of John's post are still highly relevant.

    Whatever was wrong seems to have just gone away on its own so I am marking this as solved.
