Laptop refuses to network

Laptop refuses to network

I have a Compaq nx6110 laptop which refuses to see the network when it attempts to connect. It is running Windows XP Home, and is trying to connect to a TCP/IP Ethernet 10 Mbps network with one HP (desktop) system running XP Home, and two Compaq desktops running Win2k SP4.

The laptop can ping any other system over the network, but cannot see them through Windows. The other systems can see it on the network, but cannot access it in any way (including by ping). All of the systems are being assigned an IP address dynamically, and no other system has a problem seeing or accessing any other system.

Re: Laptop refuses to network

SMK,

There are a number of things that could be causing this. First off, I am assuming that you are using a hub or switch to connect all these PCs together. Have you tried plugging the laptop into one of the other ports on the hub? or tried a different network lead.

When you plug the laptop in, does it's NIC LEDS light up at all? and also if you have access to a company LAN or similar does the laptop work on that? If not then I would suspect the NIC drivers are faulty and will need updating

Re: Laptop refuses to network

1) I have tried both changing the cable and the port; even on the exact same port as another, working computer and using its network cable, the laptop suffers the same condition. Also, both the cable and the port that the laptop is on work for other computers.

2) The NIC lights do light up when the laptop is connected.

3) I do not have access to any network besides the one that I am trying to connect the laptop to.

Re: Laptop refuses to network

Is this system a member of the same Workgroup?

Make sure of the assigned IP address (ipconfig /all).

Are any of the other systems using their hosts or lmhosts file to provide the browsing ability?

Usually, one of the systems will attempt to become a Master Browser. XP Home wins out over 2000, so the HP should be the Browse Master. Can the HP system ping the Laptop?

The other possibility is that the laptop is trying to auto negotiate 100MB rather than 10MB. Try setting the NIC at 10MB manually.

Re: Laptop refuses to network

1) The laptop is a member of the same workgroup as all of the other systems.

2) Ipconfig is giving me the same ip address that Windows is.

3) Hosts? Browsing? You're talking about areas that seem to be outside my experience.

4) The HP system cannot ping the laptop.

5) The NIC is set at 10 Mbps; same as all the other systems.

Re: Laptop refuses to network

Windows SP2 firewall enabled?

Another firewall software installed?

Do you have a Wins server on the network?

Is netbios enabled over TCP/IP?

No. TCP/IP is the default protocol that's running on WinXP. Besides, A Dell WinXP Home system & 2 Compaq Win2K systems are working fine with file & print sharing running on the system.

Re: Laptop refuses to network

Hi SMK
Well, let's look into something diferent.
The icon of your lan (is it on a bridge?) shows limited connectivity? Uninstall the NIC adapter and let Windows find it.

Did it help?

Make sure you have the same user name and password on each of the units.

This issue is probably an authenication problem.

Restart and try to browse...........

Re: Laptop refuses to network

I have a very similar problem except that none of my computers are HP or Compaq (am I allowed to speak here?).

One existing PC in a 3-PC home network died and a new PC was purchased, running Windows Media Center Edition. It works great on the Internet but like SMK's situation won't see the other computers and vice versa. The other two are running Win XP Home Edition SP2 and Win ME (I just reverted this from Windows 2000 Pro which got very sick).

All my knowledge and that of others on other forums is not helping. I am getting close to uninstalling Norton Internet Security which came as a 90-day trial on the new computer and installing the free A-V program Avast! which I use on the others to see if that is the issue.

Re: Laptop refuses to network

Yes please uninstall that version of Norton.
Go with the Systemworks version instead.

Also, Please enable sharing of your hard drives in "My Computer" or "File Explorer" tools. Then enable sharing at the folder level as well on the PCs you want to access.

Right click on the hard drive letter or folder name...............

Again make sure the same login accounts and passwords are on the other PCs........

>>Go with the Systemworks version instead.<<
I'd rather just stick with Avast! for A-V, ZoneAlarm for firewall (at least on ME, so far using XP SP2's firewall on XPs), and various free anti-spyware.

>>Again make sure the same login accounts and passwords are on the other PCs...<<

That is necessary? I never heard that before. I was told that Guest account needed to be activated so I did that on the 2 XP systems. I have some personal user accounts set up on the XP systems but not necessarily the same and not requiring passwords.

I have no Windows login requirement on the ME system. Someone recommended installing Netbeui on all 3 systems due to one of them being Win9x (ME) and that's simpler and more secure than TCP/IP. What are your thoughts on that?

Re: Laptop refuses to network

Although Zone Alarm is a standard, most people I consult with are using hardware firewalls instead of software based firewalls - the environment is more stable.

Avast might be fine, but does it remove errors in the Windows registry or cleanup cached files? Norton does that........
Scheduling works fine with Norton.

Probably since you are stuck and your friends are not networking techs or admins, their information might not be well thought out. Again the key to accessing other PCS is authenicating with passwords. The ME PCs also need passwords. The "Netbeui" protocol is legacy technology that is not needed when you have TCP/IP protocol working. Be sure to enable sharing of your hard drives.
Netbeui is not exacting anymore secure that TCP/IP, or Microsoft would be wanting to use it instead of TCP/IP.

Finally, please do not enable your Guest accounts for normal login on the XP PCs, as that would be a security breach, which means anybody can log into your PCs.
