Networking troubles - xp pro
Posted by jeff@msn.com.net on March 18th, 2006


Hi,

I have 2 computers with XP Pro, both are connected to internet. I
have a cable modem and a switch, both my PCs connect to the modem
through the switch. Internet is working fine on both pcs.

Workgroup name - NET501 (on both pcs)


I've run the network setup wizard on both pcs.


My main PC can see the workgroup when I click 'my network places'. My
2nd pc cannot see the workgroup, when i click to view network places
I get an error that I don't have permissions for the workgroup Net501.


Ideally I should be able to just connect to the other computer via the
command prompt. \\computer\share , but that isn't working either.


What am I missing here? Im never asked to log into my network
either, when Im on my 2nd pc it should be asking me for a user name
and password, but it never does (for the workgroup).


User names / account names question. Do I need accounts on each PC,
duplicate accounts? 'user1' on both machines, with identical
passwords?



thank you !

2 PC , XP Pro , Internet works via switch / cable mode, same workgroup.

What's with this wizard? It seems to be mentioned a lot and often a
cause of problems or not doing what's expected.

www.google.com try a simple search like
windows xp browse workgroup
you get -
http://www.google.com/search?q=windo...owse+workgroup

Or the MS Support articles as XP Pro is a MS product,
http://support.microsoft.com/search/?adv=1

Disconnect the 2nd PC , reboot it and browse the workgroup it should see
itself. You may need to create a share on on itself for this test.

So you are getting an error message......

Your firewall settings allow File and Print Sharing , trust the local
network.

Fast User switching, only 1 account, using C-A-D or what?

Remove the network connection, remove TCP/IP, NIC driver , reboot and
setup networking again.

Yes, it's been said in past posts before.
http://groups.google.com/group/24hoursupport.helpdesk?
also look for the lists of home networking links quite a few have step
by step guides.

Rather then a user account think of it as a (data) share account, with
it's own name / password and share permissions. This way it's common for
all users and you don't have to manage it depending on the user /
getting a new PC and adding user1 to it. You only need to set up 1
account on 1 PC, it works just fine for me.

That was your first mistake was to use that network wiz, IMO.

I always go to Start Button/My Computer/Computer Name/Change Button and
set the Workgroup name manually. There is no need for some wizard.

It must be the wizard or you have something spelled wrong.


No you don't have to have them identical on both machines but it's the
preferred method. You can have different accounts with passwords. What
you need on the share folder removing all accounts off the share folder
is use the Authenticated User group on XP Pro Shares, which means on the
computer the user account and paw needs to be created using UserManger.
It's kind of like the Everyone group account that lets every job blow
access the share but it's not as only someone giving a valid user ID and
psw that as been established on the machine can access the share.

Authenticated User group is be talked about in the link.

Your cable modem might also be a router doing NAT - we cannot see this from

So please copy the output of a

If you have separate official ip addresses, you may be lucky and they are on
the same subnet (probably if you purchased your broadband wit 2 pcs). You
may as well have two different subnets, when the 3rd part of your IPs
differs (as you will usually have 255.255.255.0 subnets, viewable in the
"route" output).

Beware: windows xp disables local network access for passwordless accounts.

Remember: if you have no nat router (would be much better than a switch

You can and should configure both windows firewalls to accept file sharing
(ports 137-139 and 445) only from the IP address of your other computer.

C:\Documents and Settings\MikeD>route

Manipulates network routing tables.

ROUTE [-f] [-p] [command [destination]
[MASK netmask] [gateway] [METRIC metric] [IF
interface]

-f Clears the routing tables of all gateway entries. If
this is
used in conjunction with one of the commands, the
tables are
cleared prior to running the command.
-p When used with the ADD command, makes a route
persistent across
boots of the system. By default, routes are not
preserved
when the system is restarted. Ignored for all other
commands,
which always affect the appropriate persistent routes.
This
option is not supported in Windows 95.
command One of these:
PRINT Prints a route
ADD Adds a route
DELETE Deletes a route
CHANGE Modifies an existing route
destination Specifies the host.
MASK Specifies that the next parameter is the 'netmask'
value.
netmask Specifies a subnet mask value for this route entry.
If not specified, it defaults to 255.255.255.255.
gateway Specifies gateway.
interface the interface number for the specified route.
METRIC specifies the metric, ie. cost for the destination.

All symbolic names used for destination are looked up in the network
database
file NETWORKS. The symbolic names for gateway are looked up in the
host name
database file HOSTS.

If the command is PRINT or DELETE. Destination or gateway can be a
wildcard,
(wildcard is specified as a star '*'), or the gateway argument may be
omitted.

If Dest contains a * or ?, it is treated as a shell pattern, and only
matching destination routes are printed. The '*' matches any string,
and '?' matches any one char. Examples: 157.*.1, 157.*, 127.*, *224*.
Diagnostic Notes:
Invalid MASK generates an error, that is when (DEST & MASK) !=
DEST.
Example> route ADD 157.0.0.0 MASK 155.0.0.0 157.55.80.1 IF 1
The route addition failed: The specified mask parameter
is invalid.
(Destination & Mask) != Destination.

Examples:

Interface^
If IF is not given, it tries to find the best interface for a
given
gateway.
CHANGE is used to modify gateway and/or metric only.

XP Pro , switch , cable modem, same workgroup.

If the switch (you didn't mention model) is really a switch then your
ISP is most likely giving you 2 IP addresses.

You need to do ipconfig/all on both PCs, not just the 1 you pasted in
earlier.

However what you did paste (snippet)

IP Address. . . . . . . . . . . . : 192.168.0.3
Subnet Mask . . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . . . : 192.168.0.1
DHCP Server . . . . . . . . . . . : 192.168.0.1

Looks like your switch is really a router (with built in switch).

If you do ipconfig/all on the 2nd PC, the IP(similar), name and MAC
address will be different.

On the PC that can't see the workgroup. Is that -
a) the workgroup name doesn't appear
b) the name is there but you can't browse the WG.

Basically that bit's all automatic, the browsing of workgroups, in the
background Windows PCs love to advertise the workgroups / browser info,
become a browse list master.

You could try removing i.e. changing the workgroup of the 2nd PC. Turn
the working 1st PC off. Change the WG name of the 2nd. See if that's
okay isolated on it's own.

If it's okay , change the WG name back and reboot, check it's okay.
Power off.

Connect both PCs back to your switch, switch on the PC1 , the one that
your could see the WG on initially. Give it 5 minutes for the WG names /
browsing to settle down the turn on PC2. Create the same username /
password account on both PCs and a share , something obvious like
PC1-temp and PC2-temp. Set the permissions to the selected username.
From each PC browse My Network Places to the other PCs shares you just
created.

Sometimes an error message / number code is handy, you usually get this
from the CMD promt.

From PC1 and PC2, putting in the real names where needed

how to list shares on a specific PC -

net view \\pc2name
net view \\pc1name

how to list the PCs -

net view


how to map to a share as a user account on PC1 from PC2-

net use * \\pc1name\sharename /userc1name\username *


The 1st * is pick a drive letter , replace
pc1name , sharename , username with the appropriate real values.
The 2nd * prompts for the password.

If that fails you usually get a 1 line error message / numeric code.

Another thing to consider is simply a packetfilter / firewall, either in the
router (there should be some setting to allow filesharing on trusted
network in the config webpage of the router, but it may as well be locked
by his ISP if the cable modem does the job) or XPs own firewall(s) turned
on and "allow netbios" unchecked.
The most simple way to detect such mishaps is to telnet one PC from the
other, with specific ports, from a cmd line:
"telnet 192.168.0.2 445" and "telnet 192.168.0.2 139" from 192.168.0.3
and vice versa from 192.168.0.2 to .3 or whatever addresses are used.
Watch the window title, when it changes to "connected".

It looks okay, the metric , the 20 at the and of the lines seems a bit
high. Not something I compared against other XP PCs a lot. 2 XP PCs
here, with only the single NIC have a metric of 10 , so I guess it's the
MS loopback making it 20.

Looks fine, what it's showing is
Network Destination Netmask Gateway Interface Metric
read this as ND - NM - GW - IF - M, saves me some typing.

A /very/ rough guide to route print

ND - Where you want to get too.
NM - network ID
GW - where to go to reach non / local destinations
IF - which interface to go via
M - cost of crossing an interface.

The short version - It looks okay.

Ok. So if the modem is nothing more but a modem (and not another router),
you would need two worldwide reachable independent IP addresses - not of
the "private" ranges (RFC1918?) that can occur multiple times and are never
routed across the internet, like all addresses starting with 10. or
192.168. - so to clarify this, put together your pcs, the switch and the
cable modem, and run "ipconfig /all" on both pcs, and post the result.

Hmm, so your modem _must_ be a router with NAT indeed. These 192.168.
addresses cannot go into the wild (internet) unchanged. Just check with
http://whatismyip.com/.

The 1st case usually requires 2 public routable IP addresses from the

reboot the CM then the PC so it can resync addresses.

The 2nd case, doesn't. The router connected to the cable mobel provides
translation of the 1 public ISP IP address in to the private 192.168.x.x
range. That's called NAT.

Leave it as the router to switch to your 2 PCs setup.

It's the easy and simple solution. Right now I have cable modem to
router. Port 1 on router is an uplink to 1Gbps switch (3PCs) , Port 2 on
router is uplink to 10/100 dual speed switch , wire runs to another
