One Computer Cant See Others On Same Network
Tezdread Mar-30-02 06:21 PM
Hi, I am having a few problems getting one of my Win2k computers to see the others on the network. The computer that can't see the others is a laptop running Win2k, I have unistalled the network devices that I can and reinstalled them again but still no joy.

I have a Linux Distribution as the FTP Server/Gateway and this is part of the "MAIN" workgroup, my laptop can connect to the internet so I know that it is connected and all the hardware is working ok. I can see the laptop from the other computers just not the other way round?

Can anyone give me some advise?

Thanks

Check workgroup and computer names (http://duxcw.com/faq/network/names.htm). Be sure file and printer sharing is enabled. Check to see that you have a common protocol installed. Please send your network configuration info. Larry

Hi and thanks for your help, it's taken a while but I have a bit more info.

I have a workgroup and a domain on the network but I haven't worked out how to get the workstations added to the domain, but that's a different problem. At the mo I would just like to get them communicating properly.

The computer (laptop) that I am having the trouble with has the following settings.

- Windows 2000 Pro
- Computer name 'T2'
- Client for MS networks
- File and print sharing for MS
- Internet Protocol (TCP/IP)

Settings for TCP/IP are:
- IP address 192.168.1.102
- Subnet Mask 255.255.255.0
- Default gateway 192.168.1.100
- Preferred DNS Server 192.168.1.100

It is part of the 'main' workgroup.

I can ping all the other computers on the workgroup and the server but when I try to ping T2 from all of the other computers I get timed out. I can surf the web using Internet Explorer and Netscape but when I try to ping an external site I get timed out.

The other Windows 2000 Pro workstation has the same settings as the laptop apart from the IP address which is 192.168.1.101 and that connects to all the other computers.

I also have a Windows XP (Home Ed)which connects to the network ok again with the same settings. IP 192.168.1.104

The server is set as a domain contoller 'homeserver.local' and when I go into Entire Network I can access the 'main' workgroup and the 'homeserver' network.

I am totally confused as to what the problem is. I guess that it has something to do with the windows configuration but other than formatting the drive and re-installing everything (which is not an option) I dopn't know what else I can do.

I hope that you can help

I am also unable to ping any external site/server from the other computers?

If you have Windows set to login to a domain controller and also a Windows peer-to-peer workgroup, the domain and workgroup names have to be identical. Workgroup names cannot exceed 15 characters (other rules: http://duxcw.com/faq/network/names.htm). Also, there is a knowledgebase article and discussion of it in this forum about getting around this limitation where the domain is name.2ndname, by using one of the names, as I recall. I havenít time to look for them right now. You can surf, but you canít ping??? I would do the LAN first and worry about the Internet after it is fixed. Larry

Hi,

It sounds like to me that a router has an Extended
Access Control List per protocol meaning that you may be
able to use HTTP in IP but it will not allow you to use Ping.

Try to telnet from one to the other or use IP route.

Hi and thank you for your help.

I have found what the problem was. I had installed ZoneAlarm on the system and this was the first thing I disabled when I couldn't see the network. I had removed it from the startup folder so I was under the impression that this was not running at all. I decided to un-install it to see if it made a difference and as soon as I rebooted my system I could access the rest of the network. I believe it was minilog.exe that was running in the background but I was unable to 'end task' it.

Thanks again
TezDread
