REG-Internet Error(Network configuration)

Dear All,

I have found the following error when I launched Internet browser. Can any one explain what happened wrong in my network configuration?

Netscap Error
Warning:
The following hosts are unknown

		Home.netscape.com
		Home6.netscape.com
		Internic.net

This means that some or all hosts will be unreachable.
Perhaps there is a problem with your name server?
If your site must use a non-root name server, you will
need to set the $ SOCKS_NS environment variable to
point at appropriate name server. It may or(may not)
be necessary to set the variable, or the
SOCKS host preference, to the ip address of the host
in question rather than its name

Can you ping them?

can you try this and share the results:
ping Home.netscape.com

Can you also try this and share the results:
ping google.com

And can you try this and share the results:
ping 64.233.167.99

This will tell us if you have access to a DNS server and/or can go outside your internal network.

regards,
Johan Louwers.

Dear Johan,

Some time I can connect the Internet, but it asks the following thing,

The server www.sun.com
Wish to set a cookie that will be sent only back to itself
the name and value of the cookie are:.
staload=star=feb3
do you wish to allow the cookie to be set?

Some time I can connect windows PC to Solaris through ftp, some time I could not contact.

I have one more error whenever I open the terminal I have found,

Jun 14:07:42:29 wkabt001 Ip:warning IP: Hardware address '00:14:85:ac:29:0e' trying to be our address 141.86.XXX.XXX!

Could you please help me to resolve this issue?

Thanks and Regards,

Sounds like you have a wrongly configured switch in your network or your network card is in promising mode. Meaning that "somehting" (a switch) is sending all the packets to the same port .... could be a flushing MAC forwarding table.....

Or it could be something else wrong on your network... maybe someone is trying to boot a pc with the same IP in your network?

Please do a ifconfig and post the results...
Plase do a (if you have a connections to the internet) traceroute to google and post the results so we can view what steps it takes to get to the outside world.. Please indicate when you leave your company network.

Thank you for your reply,
