Network connection issue

I have 2 windows 2008 servers:

Server1 is is DC
IP=10.35.27.4
SM=255.255.255.0
DG=10.35.27.1
Prefered DNS=10.35.27.4

This server can ping itself, loopback and DG 10.35.27.1
But it cannot ping server 2 (10.35.27.6)
firewall is on

The other server 2 is standalone server it is in a workgroup.
IP=10.35.27.6
SM=255.255.255.0
DG=10.35.27.1
Prefered DNS=10.35.27.4
This server can ping DG 10.35.27.1, can ping 10.35.27.4
firewall is on

From a PC in other subnet that has an IP 10.35.9.3
 I can ping server 1, but can't ping server 2
I can ping DG 10.35.27.1

any idea?

Thanks

What we know for sure is that the fault must reside in server 2.
This must be security software blocking the request.

First, try to put the firewall off on server2. Can you ping it now?
In windows firewall, there is an advanced settings-tab. Here you can block echo requests.

If you cannot ping the server with the firewall off, check if there is other security software installed. Security software like Norton can block the requests too.

this is clean installation of Windows 2008 Enterprise edition.
even if I put the firewall off it doesn't resolve the issue.

the only difference that I know of is one copy of windows is 2008 x64 and the other is x86.
I don't think this will be an issue.
and one server is a DC the other not yet, it's a standalone.
Do you think x64 are more tighter in security than x86 ?

Indeed, you can mix x64 and x32, this wouldn't do anything about the connectivity.
The security for both is the same.

No machine can ping server2 on it's IP. It seems server2 does not accept any incoming traffic at all.

Since there is no firewall or other security software, there must be something wrong with the nic.
Since server2 runs on a x64 OS, the best thing you can check next is the NIC driver.
What NIC do you use? we can check if there is an updated X64 driver available.

If there was a problem with NIC on server 2, do you think it can ping the DG and server 1.
