LAN with laptop

I have a company laptop set up to talk to the Domain at work.

At home I have a Workgroup LAN set up, with all pieces going through a router then out through a phone modem.

When I connect the laptop to the network, it gets Internet access but I cannot access it from the other machines on the network, nor even see them.  Likewise the other machines can neither see nor talk to the laptop.

Oddly, when I connect to the router, the router cannot ping any machine!

Assuming the desktop is set at and the laptop is set at auto (and gets ip how can I get the two to see each other so that I can transfer some files.

(And note that I previously tried to temporarily configure the laptop to be part of the workgroup and that totally screwed things up until the company IT department reset the laptop.)
4 Solutions
Sounds like your IT dept. has the firewall enabled (and should be). If you know the IP of the laptop when hooked up at home and you have administrator privileges   on that laptop when you logon (at home), try \\LAPTOP IP\c$ and you should see the c: drive of your laptop from the other PC. you can then transfer files from there on.
here is how you do this.

first check if your laptop is configured for DHCP or with a static IP address.

If its configured for DHCP then you need to assign static IP to it( from same subnet as your desktop have).

Now check if firewall is not enabled on either Desktop or Laptop.

How are you connecting your Laptop and DEsktop at home. Do you have a hub?

Now you should be able to ping each of the machines from other.

If you are using windows xp, I would check the Windows Firewall. Go to Start >> Control Panel >> Windows Firewall. If the firewall is turned on, momentarily turn it off and try to ping your home computers. If you can ping them, you found your culprit.

OK, partial points to hangeles and juan.

The laptop is on XP and the firewall was on.  Turning it off, I was able to ping it from the desktop, but still not access it using the IP/C$  (how do I enable an IP in Windows Firewall?)

On the desktop side, I'm running W2K with ZoneAlarm firewall.  I enabled the IP where the laptop is located but still can't ping the desktop from the laptop.

(I don't care if they can both see each other, as long as I can transfer the file.)

File sharing is enabled on all parts on both sides.
Also, the desktop is not using DHCP but the laptop is Fixed IP.
On the laptop, I see 3 enabled connections: Local Area/Ethernet controller, 1394 Net Adaptor, and Wireless.
I know the wireless lets me connect out and one of the others (if I'm plugged in), but I'm not sure what the 1394 is versus the Ethernet controller.  Which do I set the static IP and what do I put for DNS (same as desktop?)
If the objective is to simply transfer files from and to the laptop machine, and provided you have administrator privileges on your logon account to the laptop, you should be able to access the root files of the laptop drive thru the following procedures...

From the desktop PC; click START, RUN, and type on the field the ff: \\"laptop IP Address"\c$ (without quotes); click OK and it should open a windows with the list of the files and folders of the notebook C: drive. You may be prompted for the username and password; supply the username and password of the laptop local user account with administrator privileges.

Hope it helped.

"The network path was not found"
rspahitzAuthor Commented:
However, pinging still works.
First off.....your connecting via Dial Up Modem....if so....being the IT director I would tell you get DSL or Cable Modem....and then we will talk...
rspahitzAuthor Commented:
Actually, it's a DSL phone modem.  I just called it phone modem.

So let's talk.
Why can't I talk to that machine?

What are some quick alternatives?  FTP? Telnet?
I really wish I understood this stuff so I can have a fully functional LAN.
While Sharing the drive or folder assign full control to everyone and than try and access the system from explorer using the // IP address / Share. Best of Luck

Something I've seen somewhere else which may not solve the conection issues but may solve some other issues you may have is changing your workgroup name to that of the domain, so if your domain was called DOMAIN you would change the workgroup name on all of your home PCs to DOMAIN.   I can't say I've tried this in practice myself, but I've heard it does resolve some issues that can otherwise occur.
on your notebook, from a dos prompt; run IPCONFIG /ALL and post back the info here.
I just ran across this last night with two XP laptops doing an ad-hoc wireless connection... I could ping both ways, but the work laptop would not connect to my home laptop's C$ share.  I simply created a new share of the root/folder where I wanted to drop/pick-up files and was able to connect to my home laptop, from my work laptop, using
\\{home laptop IP}\{new share name}  and providing home laptop user credentials...

Hope this helps,
Check Your Windows Firewall Setting it should be turn off or you shuld have checked the File and Printing Sharing & also the ICMP request in Advanced ---> Local Area Connection ---> Settings.
If you have any other firewall install on your Laptop like Norton you have to turn that off also.
After that you will be able to Ping it & can gain access on your drives also. (For Administrator it is Hidden Share so you can access any drive by putting "$" sign after drive letter,or share the drive).

1) I set up a separate share (full permissions to all) on the laptoip and turned off the Windows firewall (no others installed per ICMP).  Win2K desktop still can't see the laptop but can ping it ad I see it in My Network Places but can't see any shared items.

I tried tracert and it goes directly from desktop to laptop
rspahitzAuthor Commented:
I just shutdown ZoneAlarm and I was able to see the laptop....

What setting in Zonealarm lets me see the laptop so I can still be protected from outside intrusions?
rspahitzAuthor Commented:
OK...got it...Firewall Zones, Advanced, Allow Outgoing DNS in trusted zones.

Thanks all...now I'll have to figure out how to distribute the points.
rspahitzAuthor Commented:
Ultimately, the first post was the right one, but it was many of the other posts that allowed me to figure out how to get it working.

Thanks all.
Thanks for the points...

Good luck.
