Ping: request, no resquest....

I have got 4 servers HP proliant. 3 are dl 360 g5 and one is dl 380 g5. Those
four with the same net problem. They have two net cards and a software
that it negotiates them. At the beginning we thought that it happened him/her alone to the server of domain.
These machines have less than one year. We have realized the problem now that we have put cable to the second net card.
They possess each one:
Two xeon 2.0ghz
4GB
SO w2k3 standard edition R2 x64, in English.
Without activating firewall of Windows.
Upgrades activated Windows and automatic.
The technical phone service of hp has just passed to its department of engineering this problem after many tests, they say that not they can make more.

Problem:
When starting the servers, the connectivity with the wan or the net-lan, I want to say the ping –t www.google.com or ping with my place of vpn doesn´t work, when pass a time it works a time, after other minutes again doesn´t work, and so.

Interesting data:
The problem sticks to alone beyond the router, since the connectivity with
the lan is normal.
Another server that we possess old, of another mark and with one net card,
doesn't have this problem.
We possess two routers with exit to Internet. Each one has created one
vpn with a different headquarters.
Other pc's with a net card, inside the lan and of the domain Windows in
that they are also the servers in question, with same DNS and the same one
gateway, they don't have this behavior.

Solution intents:
-Net configuration with another link door, since we have two
routers, and also also other DNS's, that is to say, not the dns of the server of
I dominate, but one of Internet.
-uninstall antivirus panda.
-Software upgrade HP network configuration utility, of firmware, of
driver and of bios.
-HP changed the motherboard that it integrates the net cards.
-Uninstall of devices of net , I restart and driver upgrade of net, as well as upgrade of the sw. The sw of net hp one is not able to unisntall, is not in to "add or to remove programs."
-Upgrade of different devices of Server with a package of HP called support pack.
-All the possible on configurations with the sw HP NUC.

Solution of urgency:
After restarting the servers, in net connections, to disable and to return
to enable the connection of net of the hp team. Or, directly to disconnect the one
net cord corresponding to the connection of secondary net. Or, to disable the
connection of secondary net.
Or, not to use the hp sw, to put them independent.

are you in favor of the windows upgrades?.
you have some advice, fight, helps, he/she devises, solution, solution intent
that to give me?.
Thank you ,and sorry about my english, i´m from spain.

To uninstall the HP NCU go to start -> Settings -> Network Connections. Right click on one of the network card and select properties. Under "this connection uses the following items", select the HP Network Configuration Utility and click uninstall.

Things to check

Disolve the network teaming. Is the problem related to both network cards? Are both cards connected to the same switch?

make sure the current speed and duplex are set. The switch port that the server is connected to must have the same settings.

Check the subnet mask and default gateway. Can you ping via the ip address? If it does not work via the name it may be a DNS problem. Can you do a tracert using IP address?

Check the cables, try different patch cables. Check the lights on the back of the server.

Go to the system management home page for the server and select the network card. Are there any errors being reported? Also check the port on the switch that the server is connected to, are there any errors?

Hope this helps

Disolve the network teaming. Is the problem related to both network cards?.
-When i disolve the network team, you can work with an ip for every card.
Are both cards connected to the same switch?
-Yes, and i have checked in other ports and in other switch.
make sure the current speed and duplex are set.
-His config is: auto. I haven´t tried another.
The switch port that the server is connected to must have the same settings.
-Ok, well, but i have check in other switch with other mark and modell.
Check the subnet mask and default gateway.
-I have cheked and with others.
Can you ping via the ip address?
-No, no with netbios name and no with ip number.
If it does not work via the name it may be a DNS problem.
-It don't make ping a www.google.com, but i will probe to the name of the pc in other headquarter, because, i only probe his ip.
Can you do a tracert using IP address?
-i will probe.
Check the cables, try different patch cables. Check the lights on the back of the server.
-That is checked.
Go to the system management home page for the server and select the network card. Are there any errors being reported?
-All is correct there.
Also check the port on the switch that the server is connected to, are there any errors?
-That is probed.
A lot of thanks.
When i know more things i'll say you.

Hi,

Firstly don't worry about your English. It's a lot better than my Spanish !

Another question... How did you build your servers ?

I've seen similar problems when using RDP (Remote Deployment Pack) to install a number of servers. This caused problems because the software MAC address of the network team got copied to all my server installations. Consequently our network switches got confused as to which machine was which.

If you can, try and look at the ARP table and/or MAC address table on your switches. That might show where the problem lies.

Hope this helps,

Regards,

Rob

Thanks a lot.
There is solution.
My vendor gives me solution and not HP.
Only to put in mode network tolerancy fault, i think. Good, the way for to work with only a nic, and with the other if the fisrt don't work.
The switch with the mode balancing load of the machines don't work very well, but why not in the lan and yes in the vpn and internet.
Ok. Thanks.
