Server Second nic causes ping to fail
Posted on 2013-05-28
Windows 2003 R2 Enterprise Edition SP2 all updates.
This server is used for VPN accces running ISA PPTP
This server replaced an old server running Windows 2003 with two nics that one worked no problem
A Dell PowerEdge 860 with two embedded nics
When both nics are enabled I am unable to ping any network address.
Both nics are on the same subnet.
Nic 1 ip 192.168.1.22
Nic 2 ip 192.168.1.23
With the nic enabled I can not vpn in was getting 718 errors.
So then I started testing
ping fails to ping any address on the local network
Then tried from another computer
ping servername to test dns.
it failed it was using the ip address of the second nic
In the properties of the second nic I do not have checked register this ip address in DNS
that is unchecked.
Only for Nic 1 I have that checked.
But when I looked at my DNS records both ip addresses were listed in the zone
I tried to ipconfig /flushdns no luck.
So no I have nic 2 disabled and all is working for the network
I need the second nic for the vpn traffic.
I compared all the settings from the old computer
Do not see what I am missing here.
Any ideas or suggestions
