Listed
here are the test objectives that you should know
in order to pass the NT Server Exam.
NT
Server 4.0 is very similar to the Workstation exam.
One of the major difference in NT Server; Domains,
RAS, RAID, and Global Groups.
Install
NT Server 4.0 in any given situation on a Intel Platform
using client disk or boot disk.
Setup different types of fault tolerance, ie. RAID.
View
and setup Memory dump files on the server.
Setting up Printer Pools on the server and allowing
other people to download printer drivers from the
server.
Create global and local groups and be able to manage
these groups with the proper permissions across different
domains.
Ability to view and troubleshoot NT Server with tools
such as Device.log, Dr. Watson, Event Viewer, and
error messages.
Recognize the ARC path name for any given hard disk
partition on SCSI or non-SCSI devices.
Administrate network from remote clients using Windows
NT WK, RAS, and Windows 95 client machines.
Setup, manage, and modify services for Netware such
as GSNW or Nwlink protocol.
Implement the proper file system and know all the
limitations of the file system you have installed.
License settings, either Seat or Server. Know when
to use each one.
Be aware of the permissions for the default built-in
groups for NT Server. Top of Page

4.0 in the Enterprise June 11th, 1999. (Currently

|
Disk
Managment -
Understand
and practice using the disk administrator menus and
operations.
Remember,
only primary partitions can be active. You can change
the active partition by using the disk administrator
(windisk.exe)
Remember,
when you have finished all the tasks in disk administrator
you must "commit changes now" or nothing
will happen. This is similar to using a save command
for a file.
Fault
Tolerance -
Notes for backing up information using NTBACKUP.
- Do not backup tempory files.
- Backup all PDCs and BDCs registers (included the
SAM files) - remember when you backup the account
files (SAM) and you use the backups the old account
information will be used including account names
and passwords.
- NT Cannot backup the registry over the network
using the traditional NTBACKUP utilities.
Disk
Striping with Parity (RAID 5)
- All paritions are set to the same size or very
close. Paritions must been on separate pysical disk.
You must have at least 3 disk to perform this type
of fault tolerance and 32 being the maximum. This
method is slower then stiping with parity (RAID
0) and faster then mirroring (RAID 1).
When information is lost on 1 disk it can be built
from another using the parity information. This
is untrue if you lose more then 1 disk. Do not include
RAID 5 on the boot or system paritions.
RAID 0; no fault tolerance, fastest, includes disk
stripting wit
hout parity and volume sets.
RAID
1; fault tolerance,
slowest; includes disk mirroring and disk duplexing.
RAID
5; fault tolerance, no delay in information, includes
disk
striping with parity.
Domain
Models
|
Single
Domain Model:
40,000
< Users Centralized – Centralized
|
Single
Domain: Small company few departs and want
Central management of User Accounts
and Resources.
Administrator
would like to manage all accounts and resources.
|
|
Single
Master Domain Model:
40,000
< Users Centralized – Decentralized
|
100
Users, several locations, want centralized
management of user accounts.
*
Single Master Domain: Limit up to 40,000 users.
Centralization of Users but Decentralization
of Resources.
600
employees, several locations, 1 administrator
to manager all accounts and allow local administrators
to manager resources.
20,000
Users would like to manage accounts and resources
on the network.
|
|
Multiple
Master Domain Model:
50,000
> Users – Centralized – Decentralized
|
30,000
Users, Centralized Control of Users, but let
each branch manage resources.
*
Multiple Master Domain: Support up to 50,000
Users and can manager local resources
Centralized management of User accounts.
There are two-way trust between both domains
and one-way trust between resource domains.
|
|
Complete
Trust Model:
Any
number – Decentralized – Decentralized
|
*
Complete Trust: No limit, universal access
to resources and decentralized user management.
This domain model can also be considered a
MESH or mess.
Several
locations, refuse to allow others to manager
resources or accounts, only if the local administrator
allows it.
|
Local
and Global Groups
| Local
Group: |
Can
contain: User accounts and global groups.
Can’t
contain: Other local groups
|
| Global
Group: |
Can
contain: User accounts from the domain
directory database that contains the global
group.
Can
be created using: User manager for domains
for NT and client machines.
Can’t
contain: Local groups, other global groups,
or user accounts from other domains.
|
Domain
Controllers
| PDC
(Primary Domain Controller) |
Primary
Domain Controller. Every domain must have a
primary controller. This is where the authentication
takes place for users when they logon. After
40,000 Users MS recommends that you add a BDC. |
| BDC
(Backup Domain Controllers) |
Microsoft
requirements 1 BDC for every 2000 user accounts.
30,000 accounts = 30,000 / 2,000 = 15 BDC’s.
You
will be unable to change your password through
a BDC, when the PDC is offline.
|
Registry
Hacks
| Pulse
300(60 - 3,600 sec) |
This
is the amount of time that the PDC wait to send
a pulse to the BDCs. |
| PulseConcurrency
20(1 - 500) |
Increasing
will load more on the PDC. Defines the maximum
number of BDCs that the PDC pulses simultaneously.
|
| PulseMaximum
7,200(60 - 86,400) |
Sends
a pulse to all BDC's regardless. |
| PulseTimeout1
5(1 - 120) |
Shows
the time the PDC will wait for the BDC to respond
to. |
| PulseTimeout2
300(60 - 3,600) |
How
much time it will wait for the BDC to partial
update. |
Troubleshooting
| Scenerio
|
Solution |
| User
has failed to establish a session with a remote
computer? |
Make sure your both using the same protocol.
Check to see if you can see other computers
on the network. |
| While
attempting to install NT Server as a BDC, the
brings back the error that the PDC is not found? |
Verify that the PDC is online. Make sure that
the network card is functioning properly. |
| Networking

traffing? |

Reduce logon validation · Reduce logon validation
over the WAN Wish to reduce WINS traffic on
the WAN |
1.
Configure a new domain so traffic will be reduced
over the WAN. Setting up a LMHOST file on the
new domain will also reduce WINS traffic over
the WAN. |
| ·
Reduce logon validation Reduce traffic over
the WAN |
1.
Configuring a BDC on each domain will reduce
logon validation over the WAN. Having each domain
manage their own resources will reduce traffic
over the WAN also. |
