Hello all,

Here's the situation.

I have a Windows 2000 Server running as a DC on my home
network with a local domain of DC1.A.B.net. The IP
address is 192.168.1.101 (static).

I have 2 other XP Pro (PC1 and PC2)machines that are part
of this network. Their IP's are dynamically assigned from
a broadband router.

The first problem is PC1 can access the DC and PC2
network shares through network places. Both DC and PC2
can also access each other. However, DC and PC2 cannot
access PC1 through network places. "\\PC1 is not
accesible. The network path was not found."

Ping tests were successful. All have NetBIOS over TCP/IP
enabled. All hosts files are empty and Guests accounts
are enabled. Both PC1 and PC2 are not registered on the
DC's local DNS, however like stated above..PC2 is
accessible.

The second problem is I seem to have lost connection with
the Windows 2000 Server Active Directory from PC1. I am
unable to manage it using the adminpak.msi tools (I was
still able to about 2 weeks back.)

All systems have Internet access.


Please, any answers or suggestions to either one of these
problems are greatly appreciated. Thank all in advance

Tom

Hi Tom,
Can you just check whether the LAN connections on the computers are
bridged (on both computers);
1. Open network connections 2
2. Check whether there is a network connection that is shown as a
bridge icon.
3. I there is then disable it and then delete it.
If that doesn't work then please try the following:
Check to see if Simple File Sharing (Control Panel - Folder Options -
View - Advanced settings) is enabled or disabled.
For XP Home with Simple File Sharing enabled, make sure that the Guest
account is enabled, thru Local User Manager (Start - Run -
"lusrmgr.msc"), on each computer. Do any of the computers have a
software firewall (ICF or third party)? If so, you need to configure
them for file sharing, by opening ports TCP 139, 445 and UDP 137, 138,
445, and / or by identifying the other computers as present in the
Local (Trusted) zone. Firewall configurations are a very common cause
of (network) browser, and file sharing, problems.
Let me know if the problem still exists, Luke.

Hi again,

All firewalls have been turned off or configured to allow
the ports specified. Simple file sharing has been turned
off on all computers. The XP Pro machine on PC1 still
cannot be accessed by PC2 and the Domain Controller.
There are also no bridges of any kind on the connection
manager.

If there any other suggestions, please assist me. Thanks
in advance.

Some other things that I have known to help has been to manually
configure the LAN connection. First make sure that you have tried
re-running the networking wizard. If that has not worked then try the
following:
1. Open the properties for your LAN connection
2. Remove all of the protocols, services and components in the box on
the properties page (you will not be able to remove TCP/IP).
3. Then install the following:
-Client for Microsoft Networks
-File & Printer sharing....
(If the top 2 alone don't fix the problem try adding the bottom 2 as
well below
-NWLink NetBIOS
-NWLink IPX\SPX...
4. Restart the computer (try this on all machines)
Let me know how you get on, Luke.

Check out Microsoft Knowledge base Article: 260371

Sounds like you have a DNS/Active Directory issue and you
may need to check your forwarders on your DNS server and
re add your Fully Qualified Domain Name within your DNS.
Make your Win2K server your Primary DNS, have it forward
the DNS requests to the ISP and point your workstations
(and server) to your Win2k server as the Primary DNS...
