Beginner!! In my local network all PCs can use the DSL modem but...

[mercenario nr.7157892]

it is impossible to sheare folders. Also a ping between PCs don't give
results.

I use automatic DHCP.

In the past I used fixed IPs and so the PCs culd share folders and the
printer!

How can I do the same with DHCP?

Thank n advance for your suggestions.

This has nothing to do with how the computers get their IP's. You
haven't set up the local area network (lan) sharing correctly is all.

This is most commonly caused by a misconfigured firewall. Run the
Network Setup Wizard on all computers, making sure to enable File &
Printer Sharing, and reboot. The only "gotcha" is that this will turn
on the XPSP2 Windows Firewall. If you aren't running a third-party
firewall or have an antivirus with "Internet Worm Protection" (like
Norton 2005/06) which acts as a firewall, then you're fine. If you have
third-party firewall software, configure it to allow the Local Area
Network traffic as trusted. I usually do this with my firewalls with an
IP range. Ex. would be 192.168.1.0-192.168.1.254. Obviously you would
substitute your correct subnet.

If one or more of the computers is XP Pro:

a. If you need Pro's ability to set fine-grained permissions, turn off
Simple File Sharing (Folder Options>View tab) and create identical user
accounts/passwords on all computers.

b. If you don't care about using Pro's advanced features, leave the
Simple File Sharing enabled.

Simple File Sharing means that Guest (network) is enabled. This means
that anyone without a user account on the target system can use its
resources. This is a security hole but only you can decide if it
matters in your situation.

Then create shares as desired. XP Home does not permit sharing of users'
home directories (My Documents) or Program Files, but you can share
folders inside those directories. A better choice is to simply use the
Shared Documents folder.

If that doesn't work for you, here is an excellent network
troubleshooter by MVP Hans-Georg Michna. Take the time to go through it
and it will usually pinpoint the problem area(s) -

Many thanks for your explanations!
I try to understand:
1) I can use DHCP
2) I don't have to configure a LMHOSTS file
3) because I have installed NAV 2005 or 2006 with the firewall active, I
must swich off all the WinXP firewalls.
4) because I want to make simple (at the beginning), I wouldn't use the XP
Professional features.

Questions:
Is really necessary restart the Network Setup Wizard on all PCs? It is a
little bit boring! Can I avoid this?

Yes and configure the NAV firewall to allow the lan as trusted (if your
NAV program has that option).

4) because I want to make simple (at the beginning), I wouldn't use
the XP Professional features. Fine.

You can configure File/Printer Sharing and firewalls manually of course.

Excuse me, I'am really stupid; I hope you are online because I made a
mistake:
I clicked on the Wireless Network Setup Wizard in WinXP Pro and now this PC
is not able to connect to the router. the log file says:
----------------------------------------------------------------------------
------
Wireless Network Settings

Print this document and store it in a safe place for future reference. You
may need these settings to add additional computers and devices to your
network.


Wireless Settings

Network Name (SSID): WLAN-filippo
Network Key (WEP/WPA Key): xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Key Provided Automatically (802.1x): 0
Network Authentication Type: open
Data Encryption Type: WEP
Connection Type: ESS
Key Index:


To enable File and Printer Sharing on this computer, run the Network Setup
Wizard.

To set up your Internet connection, follow the instructions from your
Internet Service Provider (ISP).
----------------------------------------------------------------------------
------
I think it means that WEP security is active on the local network drive but
not on the router.
So only this PC cannot connect!

I don't know how I can remove this new configuration!

Can you help me?

Do a System Restore to before you made the mistake.
Start>Programs>Accessories>System Tools>System Restore
"Restore my computer to an earlier time".

In the meantime I deinstalled the wireless adapter and installed again.

It seams to work now!

thanks.
