It's preferred to do this in tcpexit.cmd.  Tcpstart.cmd is owned by TCPIP
and will not preserve your edits.

Can I assume that while testing you are starting named from the command
line?

As I mentioned elsewhere, I've never seen named fail this way.  It may be
interesting when we track down the reason.

Bind ships with a tool to validate your configuration files -
named-checkconf.exe.  On your setup, run it as:

  D:\servers\BIND\bind9\sbin\\named-checkconf c:\mptn\etc\named.conf

When it runs without complaining, run it as

  D:\servers\BIND\bind9\sbin\\named-checkconf -z c:\mptn\etc\named.conf

Once this runs withou error messages you are ready for a live test of
named.  My named.conf includes the following logging setup:

logging{
channel simple_log {
// 2023-05-30 SHL
file "/Internet/bind9/log/named/bind.log" versions 3 size 5m;
severity warning;
print-time yes;
print-severity yes;
print-category yes;
    };
    category default {
simple_log;
    };
};

This will log errors that named-checkconf is not capable of detecting.

Since you are having startup errors, I recommend you try

  named -d3 -g -c named.conf

adjusting paths as needed.  This should provide a reasonably verbose debug
log and might tell us where and why bind is giving up on your system.

Unlikely based on what I know, but I am not a bind expert.

I've never needed to do this.

See https://www.isc.org/bind-keys/

According to the code the 3 values are flags, protocol number and
algorithm number.

You can do this, but it's unlikely to address your problem.

Nowhere, TTBOMK.

Let's see what the debug log reveals.
