Hello Everybody,

I am having trouble with pinging and remote logging to my win2k machine.
I have Zone Alarm installed. When I do nslookup to my machine I get following result:

C:\>nslookup machine_name
Server:  dns_server
Address:  ip_address

Name:    machine_name
Addresses:  ip_address1,ip_address2

So I see 2 ip addresses attached to my machine. I did not notice this before. I have tried rebooting machine, keeping it shut for few minutes and then again trying. I have tried ipconfig /flushdns, ipconfig /release, ipconfig /renew...nothing works...I always get " ip_address1"...I cant figure out why? Please help me in this regard...I oftenly need to remote login to my machine.
Thanks
Paluindian

1. did You tried to connect/ping with zone alarm disabled ?
2. My guess is that You have two IP's connected to Your network card. Or You have two network cards in Your computer. Is at least one of mentioned ip's the same all the time ? If yes You could check it at network connection prefferences:
a) Right Click on Network neighbourhood (My network places) ->preferences
b) Right Click on the local connection -> preferences
c) Click Network protocol (TCP/IP)
d) Preferences
e) On the bottom of new window -> Advanced
f) If in the IP protocol window You have two entries that means You have 2 IP's connected to this network card. If nothing is using oneof them You can delete it.

Awaiting Your Answer

One more thing:
The 2 IP adresses could be caused by wrong  DNS configuration and this might cause the connetion problems You mentioned above. Try to getting (ping/rlogin) to this machine using ip adress rather then name

Hello ,

I'm using internal (company) DNS servers...and I know they are working as they are working for others. I have configured 2 DNS servers, primary and secondary.

Marcia, I have tried when zone alarm was enabled/disabled...this problem arrived today. I can not find 2 IP addresses in the way you explaned above. In the IP address I see "DHCP Enabled".

ip_address1 is always the machine would take up!!.

Please suggest me whats going wrong?
Thanks

I'm sorry Marcin,I mispelled your name.
And yes I do not have 2 network cards.
How can I get 2 IP addresses. nslookup on both IP addresses will give me my machine name...
Please help me.

Unistall Zone Alarm. Remove it completely from the machine.

No problem about name :)

If You can't find second IP in that way thats 99% sure that dns are misconfigured (You have two "A" entries pointing to your computer name). I think You should contact DNS admin to solve the problem. DNS may work for the others becouse it might be only Your computer name which is affected. It may not have any influence on other computers.
Try to Ping/Connect to this computer via IP adress not computer name, You should be able to do so - If You will be able to connect - contanct your DNS admins - if not we will try to look further for Your problem.
