1. a. No, b. No. On a LAN the existence of multiple subnets does not imply
a need for multiple DCs or DNS servers. Multiple servers provide
redundancy, and can improve network performance or provide load balancing,
but the need for this on a high speed LAN is related to traffic
demand/volume, not routing.

2. On the client run: echo %logonserver%. As to which DC is likely to
authenticate in an upgraded mixed mode domain, well .......see:

 http://support.microsoft.com/default.aspx?scid=kb;en-us;309273

3. Best practice for remote locations would be to configure Sites and place
a DC at each location. But with only 5 clients, this probably is not cost
effective. MS used to have a recommendation based upon number of clients at
the remote site - can't remember what it was, but it was more than 5. If
the links are reasonably reliable and logon/name resolution performance is
acceptable, I would go without a remote DC.

4. Subnets can help reduce NetBios traffic, and you can further reduce this
by designating master browsers. By default Windows machines are potential
browsers - you turn this off by stopping the computer browser service or by
setting the MaintainServerList value to No in the regisitry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Browser\Parameters

You can use the same registry key to set IsDomainMaster on the PDC to TRUE.
For down level clients, it may be helpful to use an lmhosts file, but this
should not be necessary if you have WINS. see:
