Multihomed NetBIOS problem

Guest

We have two physically seperated networks; a Gigabit switch (192.168.0.x) and
a switch stack (10.0.0.x).

All servers (Windows[AD,DNS,WINS] & NAS) and desktops run on the 10.0.0
network.
A few of our servers and the NAS are multihomed to the 192.168.0 (Gigabit)
network.

We want to use server names [\\backupNAS\database] in our webpages and SQL
servers and have the connection over the faster gigabit switch and if there
is an interruption or disconnection it should then resolve to the 10.0.0 (100
Megabit) network.

Is there a way to consistently resolve to the 192.168 on startup and only
use the 10.0.0 as a secondary? How does it change back once it is reactivated?

That is usually fine for NetBIOS.

[NetBIOS does not deal well with two NICs in the
same broadcast domain, i.e., segment/subnet.]
We want to use server names [\\backupNAS\database] in our webpages and SQL
servers and have the connection over the faster gigabit switch and if there
is an interruption or disconnection it should then resolve to the 10.0.0 (100
Megabit) network.
I presume since you used the UNC name (\\Server\share)
that you wish to use SMB shares....

There are issues with SMB sharing (not NetBIOS per se)
using multiple NetBIOS names (Google MS or perhaps someone
will post the article links).

Is there a way to consistently resolve to the 192.168 on startup and only
use the 10.0.0 as a secondary? How does it change back once it is
reactivated?

No. If you place both address using the same
name in the name servers (DNS or WINS) this
it isn't always predictable which will be used.

If you mean for non-SMB purposes, especially
for DNS resolution, you can certainly give your
machine two names by modifying the NIC->IP->
Advanced->Properties for one of the NICs.
