LAN problem with new PC

[i]

Hi!

I have a small LAN at home, for the moment 3 PC's and one "LAN-disk".
They has worked just fine, but I have problem getting my new PC to see
the other PC's or the LAN-disk.

Config:
PC 1, ip: 10.123.123.11
PC 2, (the new) ip: 10.123.123.1
PC 3, (my wifes) ip: 10.123.123.5
LAN-disk, ip: 10.123.123.6
ADSL-router, ip: 10.123.123.222

Netmask at all of the above: 255.255.255.0
I don't have NetBEUI at at least PC 1 or PC 2. No WINS server at
anyone. No DHCP (all ip addresses are "fixed").

I can ping everyone from anyone (Including PC 2). All have groupname
"GROUP1".

***But PC 2 cannot see anyone or their shares.***

The other PC's can see PC 2 and it's shares (for the moment only the
printershare - although I haven't any printer defined for PC 2).
I have checked the firewalls and their logs. Nothing is blocked.

So I'm wondering 2 things:

1. What is my problem ?

2. What is the requisites for a working LAN ? (I e sharing disks and
printers etc.)
I thought that it should work if they have a common netmask/ipaddresses
and the same groupname. And without any WINS server or DHCP etc.
(As it worked before the new PC - and still work as the other PC's and
the LAN-disk can see each other and also the new PC 2.)

TIA
Thomas

You started at the high end by checking if the PCs can "see"
each other (which presumably means that the various shares
are visible in Windows Explorer or in My Computer"). Much
better to start at the low end and build things up until they
fail. Start a Command Prompt, then see if you can ping each
machine by IP address and by name, then report the results.

I think Pegasus missed the results of your earlier pinging tests,

Have you set up a user name and password on the new machine that matches a
username and password on the others? That sometimes helps - make sure the
password at least is in the same case, the username probably won't matter.
It is very easy to think you have done this and make a stupid typo... I've
chased a few of those in my time.

(Yes, the pings works OK.)

About the username and password: I'm not sure I follow You here. Are
You thinking of a username existing on the PC regardless if it is
currently logged on (the PC/shares that I try to access), or do You
mean the one that IS currently active ?
Normally I get a prompt the first time I access another share/PC for a
username and password (and then I give those - and they also exist at
the other PC of course). And in these cases I can see the shares
beforehand (= see the names of them, not read the directories etc.).
(The username I used was not the one that was logged on, and it
worked.)

I see now that if forgot to mention that if I add NetBEUI to
network/adapter at the new PC, then I can see the other shares. But as
I have got this (the network access in the LAN) working before without
NetBEUI I rather don't want to use it.

I mean a user name acceptable to the other PCs, not necessarily the one that
is logged in on any of them. It seems like it avoids certain glitches with
windows integral authentication. However I think you should check your
network settings to see if that machine is using NetBIOS over TCP/IP... see
if changing the setting there works. It is in the "WINS" tab of the
properties. Default usually works but maybe positively switching it on will
make a difference.

OK. Yes I have such a username. But I will check it again.
About NetBIOS over TCP\IP - yes I have it.
I have checked the settings over and over again, and if I'm not blind
they are nearly identical on both PC 1 and PC2 (computer name, ip
address etc differs of course).

I know what you mean about not being blind but sometimes you can look too
hard and still not see it

Another reason for the username I mentioned is that there are two sets of
permissions with sharing, actual sharing permissions and also the NTFS
permissions on the folders being shared. If Netbeui enables viewing though I
can't see folder permissions being the problem.

Have you tried going to network places from scratch, in other words from
"Entire Network" and all the way down? I am assuming that's what you are
doing but I've seen network places get confused also.

I did notice that you picked the IP address 1 for this machine. That's often
used by default for routers, I just wonder if that has anything to do with
anything? You can more easily view folder permissions (On the machine
sharing the folder) by opening a folder, tools>folder options>view and
uncheck simple file sharing. Other than that I think my brain has seized up,
will be back later...

I have solved the problem !

I used the registry editor and compared the values under the key
"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters"
with the same at PC 1.
I noticed that they were different and much fever at my problem PC (PC
2) compared with PC 1.

So I completely uninstalled the TCP/IP protocol at PC 2, rebooted, and
reinstalled it.
And now it worked ! (I can see and access the shares at the other
PC's.) 8O

Apparently had the orginal install of TCP/IP gone wrong and Windows
doesn't seem to recheck the parameters when You change the values in
the Network/TCP/IP properties.
(Idiotic behaviour, BTW.)

Another experience to append to my collection of scars...
