Cannot connect

[SteveD73]

Hi

I have a PC which is running Win2000 and it uses a dial-up connection to connect to the Internet. It is a stand-alone PC and so it does not have a network card.

I can connect to the Internet without any problems but when I try and do any the following I get failures:

1) I cannot ping anyone.
ping

http://www.google.com

- times out
ping 'an IP address' - times out
ping 127.0.0.1 - works fine
2) I cannot FTP anyone. I have tried various FTP clients and they all fail.
3) I cannot TELNET anyone.
4) I am trying to connect to an SQL2000 Server with no success. SQL2000 Client is saying that it cannot find the connection (or something similar).

I would be grateful for any assistance as this problem is driving me mad.

Thanks

How do you know that you are connected to the internet okay? What CAN you do?

I can browse the Internet using Internet Explorer.

Have you looked at any W2k security settings? Are you logged in as administrator?

 

[SteveD73]

Yeah im logged in as Administrator. When I installed Win2K I installed it on top of Win98. Would that make any difference. My dial-up connection is a simple Freeserve connection.

It appears that only Internet Explorer can see external addresses.

hi,
your PC is going well, compliment.

What you are trying to do, rather than surf on the web,
probably is impossible.

Why google server would you permit to login on it ?
Are you sure that the google server can answer to yout ping?

If you surf on web by modem you are sure that:

your tcp-ip protocol goes well, and your internet provider,
using ppp, negotiates with you a temporary IP address
for your pc.

enter from command line

netstat -p tcp -a

this will show all tcp connection of your PC; if you give

netstat -p tcp -an

you will see some address xxx.yyy.com, translated in their
ip address: if you ping them, you are sure that Names to ip
are well tranlated, but I belive that you cannot still ping.

IP speaking, each node has one (or more) IP address: then, it may use one or more transport protocol (TCP/UDP) and
then the port:
every service (telnet,ftp,http,mail,snmp....) uses a
specific port ( 21,25,80,57897 ).
When you install a Linux box or a W2K one,
almost all these services are enabled:
if you are in a LAN, you can ping, ftp, telnet,... the
computer just installed.

If you can http//:

http://www.google.com,

you are connected on port 80 of that server: nobody ensure you that you can ping,telnet, ftp something from that IP address:

http://WWW does

not mean that you can see every thing you want on all world servers !

bye
