RE: Windows 7 - Multiple NIC binding order

2011-06-14 Thread Bob Fronk 
True, but it wasn't doing that.  It was using the lower bandwidth connection.

For some reason the Interface metric was greyed out for the lower bandwidth 
NIC.  I uninstalled it and re-installed it and can now set a higher metric on 
the USB NIC.  This has resolved the issue.

Quick Google uncovers that if you have a gateway setup on multiple NICs, by 
default in Win7 it will use the NIC with the higher bandwidth.

More testing shows that Windows seems to use Ping times to decide which network 
is "faster".  The slower network has better ping times by a couple of 
milliseconds, however, it is less than half the bandwidth, and not the network 
that has first priority in the network bindings

Subject: Windows 7 - Multiple NIC binding order

Windows 7 Enterprise 64bit with two 1GB NICs.  (NIC 1 is internal.  NIC 2 is 
USB dongle) Each NIC is connected to a different subnet, LAN 1 = Domain LAN.  
LAN 2 = Local Test network.   LAN1 is the domain LAN and has a 45mbps Internet 
connection.  LAN2 is a test network and is connected has a 20mbps Internet 
connection.  LAN1 is 192.168.x.x.  LAN2 is 10.10.x.x.   Both are DHCP.  Both 
are 1Gbit networks.

I have set the binding order for network services to use NIC1(LAN 1) first.  
The wireless (not connected) second.  NIC2 (LAN 2) third.  Windows has 
designated LAN 1 as "Domain Network" and LAN 2 as "Work network".  However, at 
each log on, the OS is using NIC2 for external traffic (Such as WEB, Outlook 
connection, etc.).  I can still connect to the domain LAN, however it is not 
primary.  I have to unplug the network cable for the OS to switch to LAN1.  If 
I plug the cable back in, the OS will switch back to NIC2 at various intervals.

I use the test network for some VMs I run on my PC for testing purposes.  I 
need external access for these VMs, but I do not want them on the domain 
network.

This was working fine for me until my old 100mbps USB NIC experienced a "drop 
and break it" incident.  The new USB NIC is 1Gbit, so I am guessing that 
Windows sees this as a "better or faster" network and somehow makes it priority 
over the Domain network.

Beyond setting the binding order (which I have done), does anyone know another 
way to force Windows to use "think" LAN1 is the best priority network?
