Network and XP

[Guest]

New to the XP world and have my daughter's computer and mine on XP. Have run
the network setup wizard 1/2 dozen times. I can see my computer on hers and
vice versa but when I try to access it, it says "I might not have permission
to use the resource. Contact the administrator." I am the admin (as far as
I know).

I have a Belkin router and am using DSL. Both computers can access the
internet and my computer can print (the printer is USB'd to my desktop).

Please help

On your PC, set up a user account & pw that exactly matches what she uses on
hers. Same in reverse. Then try.

Did what you suggested ran the network setup wizard. Still can not access
anything nor get a test page to print from her computer.

Have you set 'file and printer sharing'.. or a drive maybe?

 

[Guest]

Well, no one mention this thing to you right? Okay, Accounts can be same with
your daughter but how about Administrator Accounts? Not the local accounts.
Administrator accounts must match up too. It does not matter what accounts
you used to login to the computer. Most important one is Administrator
account. Make sure it is match up. Then see if you can access. For sure you
can. I do not think you have to run network wizard everytime you make changes
with the account. It should detect. If not so, you must do so.

These tips should help you get everything working:

1. If the computers run the original or SP1 versions of Windows XP,
disable XP's built-in Internet Connection Firewall on local area
network connections -- it's for use only on a direct modem connection
to the Internet. If they run SP2, enable the exception for file and
printer sharing in the Windows Firewall. Disable and un-install all
other firewall programs while troubleshooting. When un-installing a
firewall program, use the un-install procedure provided by the
manufacturer . Don't use Control Panel | Add or Remove Programs,
which might not completely un-install it.

For more information, see:

Windows XP Internet Connection Firewall
http://www.practicallynetworked.com/sharing/xp/ic_firewall.htm

2. Use only one protocol for File and Printer Sharing. If the network
needs more than one protocol, unbind File and Printer Sharing from all
but one of them. Details here:

Windows XP Network Protocols
http://www.practicallynetworked.com/sharing/xp/network_protocols.htm

3. Make sure that NetBIOS over TCP/IP is enabled on all computers.
Details here:

Enable NetBIOS Over TCP/IP (NetBT)
http://www.practicallynetworked.com/sharing/troubleshoot/netbt.htm

4. Run "ipconfig /all" on XP and look at the "Node Type" at the
beginning of the output. If it says "Peer-to-Peer" (which should
actually be "Point-to-Point") that's the problem. It means that the
computer only uses a WINS server, which isn't available on a
peer-to-peer network, for NetBIOS name resolution.

If that's the case, run the registry editor, open this key:

HLM\System\CurrentControlSet\Services\Netbt\Parameters

and delete these values if they're present:

NodeType
DhcpNodeType

Reboot, then try network access again.

If that doesn't fix it, open that registry key again, create a DWORD
value called "NodeType", and set it to 1 for "Broadcast" or 4 for
"Mixed".

I hope and believe that your post and the links in it will help me solve a
problem with a network on which one PC has a static address, but would
apprecaite an answer before I make matters worse! The PC is behind an Origo
ASR-8400 ADSL router, and is set up with a static address as the VPN 'virtual
server'. Does this require any action other than those recommended in your
post?

I don't think that static vs. dynamic IP addressing or running a VPN
server should have any effect on how a computer accesses other
computers or is accessed by other computers on a LAN, provided that
all of the computers are in the same subnet.

If you're concerned about the effects that network troubleshooting
steps might have, use System Restore to create a restore point before
changing anything.

That's correct - in fact, you never really *need* to run the wizard at all
if you know how to set up your workgroup, sharing, etc.

Everyone
Not sure which of the suggestions from Steve worked, but it did. I thank
all of you and my daughter thanks you as well.

I have set all the network PCs to use NetBIOS and removed the DhcpNodeType
entries from the registry but I still have a problem with one PC on a network
with a static address - I cannot access the network printer that is hosted by
one of the PCs that uses the DHCP server to get its address. When I run the
printer CD to install I get a message to say that I do not have the necessary
permissions to access the host PC. I have changed the Administrator password
to be the same on all the PCs, and a second dynamic address PC was able to
add the printer.

Static vs. DHCP addressing has nothing to do with a permission
problem.

Let's call the PC that has the static address #1, and call the PC that
hosts the network printer #2.

On #1, type this line in the Start | Run box, substituting the actual
computer name of #2:

\\computer

What happens? If there's an error message, what exactly does it say?

What happens if you ping #2 from a command prompt window on #1? Try
it using both the computer name and IP address of #2. Open the
window using Start | Run | cmd, then enter these commands,
substituting the actual computer name and IP address of #2:

ping computer
ping ip-address

Does #2 run XP Home Edition or XP Professional? If it runs XP
Professional, have you disabled simple file sharing? If so, set up
matching user accounts on #1 and #2 -- same user name and password.

Steve,

I need some help. I have a peer-to-peer network with two computers running
XP Pro through a network switch. Periodically, the network connection is
lost, and I have to rerun the Network Wizard to reconnect. Today, I was
unable to get it to reconnect even after running the Wizard. The kicker is
that the only connection outside of the network is via a modem on one of the
computers that is dials up to a insurance company. We have no Internet
connectivity on either of the computers other than that. I really thought
that this network would be simple and reliable, but it isn't turning out that
way. Any thoughts?

 

[Guest]

May I report on the result of the tests you requested: -
1.\\'computername - Windows cannot find
2. Ping computername - cannot find
3. Ping address - successful

All PCs on the LAN are running WinXP Pro at Service Pack 2, with file and
printer sharing enabled (in the firewall as well).
Both the user accounts with administrator status exist on both the printer
host PC and my work PC.
In 'My Network Places' viewing workgroup computers displays the four PCs
currently powered up on the LAN, including my work PC.
It is still not possible to add the printer to my work PC, even with the
firewall off on the host PC. The 'Add a printer' process shows the workgroup
and the printer host PC but does not show the printer.

Thanks for the report. I should have asked you to make one more test:

\\IP-address

When computer access by IP address succeeds but computer access by
name fails, it indicates a problem with NetBIOS name resolution.
These tips should help fix the problem:

1. Make sure that NetBIOS over TCP/IP is enabled on all computers, as
shown here:

Enable NetBIOS Over TCP/IP (NetBT)
http://www.practicallynetworked.com/sharing/troubleshoot/netbt.htm

4. Run "ipconfig /all" on the XP computers and look at the "Node Type"
at the beginning of the output. If it says "Peer-to-Peer" (which
should actually be "Point-to-Point") that's the problem. It means
that the computer only uses a WINS server, which isn't available on a
peer-to-peer network, for NetBIOS name resolution.

If that's the case, run the registry editor, open this key:

HLM\System\CurrentControlSet\Services\Netbt\Parameters

and delete these values if they're present:

NodeType
DhcpNodeType

Reboot, then try network access again.

Thank you for the prompt reply. I have just tried \\'ip-address and the
result has displayed the shared items on the printer host, including the
printer I want to add to my PC. The tips you gave I put in place yesterday. I
removed DhcpNodeType from all 3 PCs to which I had access - none of them had
an entry for NodeType - and tried adding DWORD NodeType for each of 1, 4 and
8 in turn. Finally I left my PC with NodeType 4 and removed it from the other
two.

A lot seems to depend on which PC runs the Network Setup wizard. The latest
state is that it was run from my PC this morning, which can now see the 3
other PCs that are signed on, but at least one of them gets a message to say
that the Office workgroup is not accessible. I am beginning to think that the
only solution to this problem is to give fixed addresses to all the
'resident' PCs and to create a LMHOSTS file for each one to point the
addresses at the names. This ties in with a recommendation from a specialist
in another forum to give fixed addresses to all the local PCs and leave the
DHCP address pool for 'visitors'.

I have been running tests from home via VPN and RDS - waiting for the gasman!

 

[Guest]

I have fixed it! I had a look in Help and Support for LMHOSTS and found 'To
configure TCP/IP to use WINS'. I followed the instructions for adding WINS
servers for a local area connection, and added the address of the router and
the PCs with dynamic addresses. I was then able to add the printer. I hope
and believe this will also enable the use of VPN to use RDS on the other PCs.

I'm glad that you got it fixed. Thanks for the report.

I'm also puzzled, because an XP Pro computer can't act as a WINS
server -- that requires a computer running a server operating system.
I've never seen a home broadband router that can act as a WINS server,
either.

Using an LMHOSTS file should work, provided that the IP addresses of
the computers don't change.

I must admit that my solution is the result of lateral thinking - why should
a PC not be prepared to supply its own name? I still have to understand how a
workgroup functions. I believe that the PC that runs the Network Setup wizard
must be up and running for the other PCs in the workgroup to be able to see
the workgroup computers. I also suspect that in my case, with my work PC
having a static address, the other PCs will see mine once I have run the
function to view workgroup computers, because this provides my computer name
and address, wqhich they cannot get from a broadcast. I must test this later
in the week when I am next in the office.

This typically occurs when a software firewall is not configured properly
(assuming the other steps Steve Winograd mentioned have been previously
implemented).

Uninstall the firewalls (not just disable them - except in the case of the
XP built-in firewall) and you may find the solution to your problem.

8 out of 10 home networking questions I receive involve people locking
themselves out of their own LANs with misconfigured firewalls. Something to
consider...
