NT Netlogon Service

1. When is Netlogon Service necessary?

A WindowsNT4.0 Server, not working as a Domain Controller, is connected
via ISDN to the central LAN with PDC & BDC inside. Netlogon traffic
occurs every 15 minutes from the NT Server to the BDC. To avoid this
kind of traffic, we want to stop Netlogon Service on the NT Server.

Is Netlogon Service necessary for the NT Server which is not PDC or BDC?
I was told that the NT Server can not be managed by Server Manager of NT
remotely without Netlogon Service. Is it true?


2.How to set these Netlogon parameters on NT4.0?

According to Q154355 of MS Knowledge Base, the following Netlogon
parameters are added in Service Pack 5 of NT3.51:
/HKLM/System/CCS/Services/Netlogon/Parameters
    ExpectedDialupDelay
    ScavengeInterval

But I can't find these parameters in NT4.0 and Service Pack 2 of it. How
can set them in NT4.0?
These parameters are for Netlogon wait time and retry interval. Can I
adjust these in another way?

The NETLOGON service is required whenever a domain logon is needed. NETLOGON provides the authentication for a user logging into a domain.

Stopping a server from running NETLOGON would disable that server's ability to verify usernames/passwords for users logging to the domain.

Preventing NETLOGON from running on a server is automatically accomplished if you do NOT set up the server to act as a PDC or BDC. (The server could be a merely a domain member, much like a NT workstation).

A WindowsNT4.0 Server, not working as a Domain Controller, is connected
via ISDN to the central LAN with PDC & BDC inside. Netlogon traffic
occurs every 15 minutes from the NT Server to the BDC. To avoid this
kind of traffic, we want to stop Netlogon Service on the NT Server.

Server manager can manage all server types: PDC, BDC, domain members and stand-alone.

First, HKLM is shorthand for HKEY_Local_Machine and CCS is shorthand for CurrentControlSet. If you can't find the keys ExpectedDialupDelay or ScavengeInterval, then merely add them. If NT doesn't see the parameters in the registry, it just takes a hard-coded default.
