Ras server suports-TCP/IP,NETBEUI and IPX/SPX
RAS AutoDial supports-TCP/IP and NetBEUI
To enable RAS.log need to edit the registry
HOST and LMHOST Files are stored on the RAS client
ARC names was my hard part I used this to study:
SCSI-BIOS disabled
MULTI-BIOS enabled
DISK-0 if multi and if SCSI # of bus
RDISK-0 if SCSI and if multi # of disk
PARTITION- is easy, # of partitions starting from 1, the rest start from 0
Explorer-manage permissions
Server Manager-manage shares
Import-NT server, recommend Domain Controllers
Export-NT servers
PPP supports-named pipes, remote cells, Winsock, IPX and TCP/IP
Questions that people had controversy about.....
server is down using mandatory profiles-Users CAN'T logon, even though transenders say that they can
IPX doesn't work always frame type-manual detect and add the frames if not 802.2
HP questions always DLC protocol
Info about TCP/IP enable SNMP
A BDC can be promoted to a PDC from Server Manager
-When the BDC is promoted, the PDC is automatically DEMOTED if it is Online while
the former BDC was being promoted.
If the PDC was offline during the promotion of the BDC, then, when you boot up the
former PDC after promotion of the former BDC, the former PDC shall not be accessible
from the new PDC, in fact, it shall appear grayed from the Server Manager of the new
PDC.
The Solution now, is to access the former PDC and DEMOTE it yourself to make it the
new BDC through its Server Manager.
PPP supports:
Named Pipes
Remote Procedure calls
Winsock TCP/IP
Winsock IPX
Excessive paging, check:
Avg disk sec/transfer
Pages/sec
Auto Dial for RAS
Only works with TCP/IP and NetBEUI
RAS works with TCP/IP, NetBEUI and IPX/SPX for dial out and dial in.

The infamous logon question regarding a mandatory user profile and the PDC goes
down. (YOU CAN NOT LOG IN)
You want to be alerted if there's a system error on any one of 5 servers. (Using Server
Manager on each server, configure it to send an alert to a group of adminstrators. The
key here is System Error. If it's a system error, use Server Manager, if it's a counter alert
such as low disk space, then you use the Performance Monitor)
You want to be alerted for low disk space on any one of 5 servers.
(create 5 alerts using Performance Monitor on your workstation and configure it to send
an alert to you)
What do you have to configure to gather TCP/IP related counters on a server?
(SNMP on the server(s) you want to gather the info on)
Dialing into RAS with clients using 3rd party software that supports DES encryption?
(Use encrypted logon authentication), not Microsoft authentication.
Clients dialing into RAS (both server and clients using NetBEUI and TCP/IP), they want
to access a Windows socket application. What must you configure on the RAS server?
(What IP address to assign the clients).
Tricky question about installing NT Server to a MS-DOS system over the network.
A couple of the answers involved using Client Administrator to create an installation
startup disk but the catch was that one answer said to boot to MS-DOS and then insert
the startup disk and run winnt.exe off of the disk. The correct answer was to simply boot
to MS-DOS, connect to the shared directory containing the installation files, and running
winnt.exe.
A couple of ARC naming questions. Just remember scsi is used with scsi drives with
BIOS not enabled, multi() for everything else.
Creating a boot disk with a SCSI drive with BIOS not enabled, what file do you need?
(NTBOOTDD.SYS)
What can DHCP also provide to clients besides IP Address?
(DNS server, WINS server, default gateway, NetBIOS name resolution)
Converting FAT to NTFS? (Use CONVERT command)
Copying files from NTFS to FAT? (Retains long filenames but permissions are lost)
Clients dialing into RAS want to be able to set their own authentication, what do you set
in RAS? (Allow any authentication including clear text)

MANDATORY LOGON QUESTION:
SYMPTOMS
Even though the Windows NT Concepts and Planning Guide states, on page 88, that,
you should be able to log on using cached profiles on the local workstation, USERS
ARE DENIED ACCESS, THEY ARE UNABLE TO LOG ON, AND THE FOLLOWING
ERROR MESSAGE APPEARS IF THE SERVER BASED MANDATORY PROFILE IS
NOT AVAILABLE:
Unable to log you on because your mandatory profile is not available.
Please contact your administrator.
Windows NT Concepts and Planning Guide Excerpt:
The Windows NT Concepts and Planning Guide states on page 88:
"If a user has a personal profile, the per-user settings are saved to both the user's
personal profile and the locally cached version of the profile when the user logs off.
The locally cached profile is identical to the updated personal profile.
If a user has a mandatory profile, changes made by the user during a session are not
uploaded to the mandatory profile when the user logs off. The user can never change
the mandatory profile. However, if the mandatory profile allows the user to make
changes during a session, any changes made by the user are saved in the locally
cached version of the mandatory profile. So, the next time the user logs on at this
workstation, if the user's mandatory profile is unavailable, the locally cached
profile is loaded, and the user will have the changes made during his or her last
session."
CAUSE:
MANDATORY PROFILES DO NOT GET CACHED ON THE LOCAL
WORKSTATIONS.
RESOLUTION: THIS IS A DOCUMENTATION ERROR.
If a user logs on and both the server-based profile and local version of the profile are
unavailable, the user is logged on using the computer's default profile, if the user has a
personal profile. If the user has a mandatory profile, the logon attempt is denied.
This is expected for mandatory profiles.
INSTALLING A SECOND PROCESSOR IN YOUR NT SERVER TO IMPROVE

Help.
1.Mandatory Profile, Server down ? User cannot logon.
2.Install Winnt from CD-ROM ? Select all that apply ? Boot to DOS, make sure dos
CD-ROM drivers installed, run winnt.exe from CD, Boot from Setup boot disk.
3.Workgroup of NT wkstns. Want to install a NT Server as a PDC. Want NT wkstns to
be in domain. ? Domain Admin to add computer acct of each wkstn using Server
Manager, and, Wkstn Admin to login to each wkstn and from ?network? join the
domain.
4.RAS clients keep getting disconnected ? enable device logging from registry.
5.RAS have 2 type of clients. Win95 and 3rd party which only recognise DES. The
most secure ? Require Encrypted Authentication.
6.RAS clients dial in to access Winsock program. All servers and wkstns have
NETBEUI and TCP/IP. What needs to be done to allow communication ? ? Select
how an IP add will be assigned.
7.Exhibit ? require clients to be able to select own method of authentication ? Any
authentication including clear text.
8.1 PDC and 3 member servers, want to speed up Logon ? reinstall one member server
to be BDC.
9.TCP/IP in a non-routed network. Need only IP add and subnet mask.
10.For NT to act as a router ? need 2 NICs, enable IP forwarding and manually assign
unique IP add to each NIC.
11.2 NT servers and a group of wkstns. 1 tape connected to 1 NT server, back up all
machines. Backup took too long. ? Connect another tape drive to the other server,
backup the wkstns, the original tape drive backup servers.
12.To monitor TCP/IP on NT servers from wkstn, use perfmon and must install SNMP
on each server to be monitored.
13.To create share on a server from a remote client, install client network tools and run
server manager.
14.To manage print security over the network, run Windows Explorer.
15.To change file permissions over the network, run Windows Explorer.
16.Printer Pool ? must ensure that all printers can use the same printer driver.
Incidentally they also share the same name. But they need not be directly connected
to the print server.
17.Printer broke down. Decided to use another network printer to finish the pending
print jobs, goto the ports tab and add a logical port with a UNC path to the printer.
18.DHCP can assign to clients, IP address, subnet mask, Default gateway, WINS server
IP add, DNS server IP add??others like DNS domain name, NetBIOS node type?.
19.Netware clients to access client/server app that supports NetBIOS on NT server.
Install NWLink on NT server.
20.Win95 and Win3.1 clients with clients for MS-networks and NWLink installed. Need
to access resources on both NT and Netware server ? Install GSNW on NT.
21.After Installing GSNW, you must create a group called NTGATEWAY on Netware
server.
22.To migrate from Netware to NT, you need Nwlink and GSNW. However if asked
what do u need to install ? ? Install GSNW will do. NWLink comes along.
23.1 HDD. 2 partitions. 1 FAT ? sys and boot partition. 2 NTFS ? empty. Want to
implement security on 1st partition. ? Don?t need to format to NTFS. Just
CONVERT.EXE from command prompt. Remember if NT is running, the conversion
only runs the next time u reboot the server. It converts at the blue screen and then
restarts again. So the server will reboot twice to convert.
24.2 SCSI adapter 2 HDD. Want FT. ? Only Duplex is possible. Mirror was not among
the choices.
25.3 HDD 1 adapter? Want Fastest access, Want Continue access in case 1 HDD failed.
The choices were really bad ? Only 2 FT choices. Duplex and Stripe set with Parity.
You tell me.
26.2 SCSI adapter. Duplex mode. 1 adapter BIOS disabled. Need to create Boot Disk in
case 1st adapter failed. What among the others files is required ? NTBOOTDD.SYS.
27.During Installation, setup did not detect your CD-ROM. Restart the setup from the
beginning and this time invoke the ?S? ? manual selection of CD-ROM drivers.
28.Exhibit ? Mirror Set, SCSI adapter. BIOS disabled. 3 partitions on each disk. What is
the ARC path to the mirror ?
Disk 0 : System | Data | Data
Disk 1 : Data | System ( Mirror ) | Data
Scsi(0)disk(1)rdisk(0)partition(2)
1.Move a file from one dir to another within the same NTFS partition. ? Permissions
retained.
2.Move a file from NTFS partition to FAT partition ? LFN retained, Permissions
discarded.
3.Your server seldoms have more than 10 connections, how to change server settings
to take advantage of the situation ? ? Server Service.
4.Exhibit - So and so just got promoted from engineer to consultant. Need to access
certain shared folder. Rights for engineer ? No access. Rights for consultant ?
Change. So and so is member of engineer and consultant group. Can he access ?
How to allow him the access ? ? Remove so and so from engineer group.
5.Suspect excess paging is causing the performance to degrade, how to confirm ? ?
Check the counter ? number of pages per second.
6.Need to be notified when disk space of servers fall under 25%. ? From perfmon. Not
Server Manager.
7.Need to alert the domain admin of any system event of the 4 domain controllers.
Add each user of the domain admin to the list for each server. One choice says add
the domain admin group to the PDC.
8.Want to backup user accounts and registry when server is running ? ? NTBACKUP.
9.Netware clients in a network. A new NT server running SQL appl is added to the
servver. How to allow the clients to access SQL ? Just install NWLink on the NT
server.
10.Just created a partition on a new HDD. Want to format now. What need to be done
first before u can format? Click Commit Changes Now.
11.Client with IPX/SPX cannot communicate with NT server. NT has Nwlink installed.
What is the most likely reason ? Wrong frame type. The other choices ? No access
to resources, Workstation service on NT not running, ?..another dubious one.
12.Exhibit ? Want to replicate files to the other servers in the domain. Where to put
the files ? ? In a subdir under winnt\system32\repl\export
13.Confirm excess paging, what to do ? ? Add RAM.
14.2 HDD. 1st one has sys and boot partition and pagefile.sys. How to improve
performance ? Shift the pagefile.sys to the 2nd disk.
15.4 HDD Want FT want to maximise disk space for data usage. 2 choices have FT.
Mirror and SWP. But question wants maximise disk space so it?s SWP.
16.Remote monitoring 5 servers using perfmon on your own NT wkstn. As a result your
wkstn slows down dramatically. How ? Increase the sampling interval.
17.Want to monitor a few servers for a week, use LOG view.
18.To assign Home Dir , use User Manager for Domain and type in the UNC path.
19.To assign roaming user profile, user Manager for Domain and type in the UNC path.
20.Your boot sector infected. You cleansed it. Whoops?the boot sector is corrupted.
Don?t fear, boot up the computer using the 3 installation disks, when prompted,
press ?R? for repair. One of the options allow rebuilding of your boot sector.
21.Mirror failed. Got a new disk. Before u try to create a new mirror, what is the very
1st thing u need to do ? Break the original mirror set.
22.1 HDD of a SWP failed. It does not contain the sys or boot partition. Got a new
disk. What to do ? From Disk Admin, click on the SWP, click on the FREE SPACE
from the new disk and choose REGENERATE from the FT menu.
23.Install NT from MSDOS station without CDROM. ? Boot to DOS. Connect to
network share and run winnt.exe from the shared folder.
24.Very long question ? basically remote NT wkstns use NETBEUI 90% and TCP/IP
10%. How to improve performance. Bind the workstation service to use NETBEUI 1st
* Know Trusts inside out (if you don't you fail - simple as that)
* Know domain models inside out (single, single master, multi-master, fulltrusts)
* Scenario: You want to give ONLY the sales group remote access (mandatory) and require data encryption AND password encryption. Proposed Solution: Configure only sales to have remote access thru usrmgr, allow any authentication method, require passwords to be changed every 40 days.
* Same scenario as above. Proposed Solution. Configure only sales to have access thru usmgr, require encrypted authentication, require passwords to be changed every 40 days,
implement hardware based security between the modems and the server
* Scenario. You have 2 identical printer devices pooled. Accounting is always hogging the printer with 500 page docs that require alot of processing. You want Managers to always print first and have both printers in the pool available to them. You want Sales to also print to both
printers but their jobs come after Managers. You want Accounting to print last and only to one of the printers.
*Proposed Solution: Configure a printer pool. Assign the Managers highest priority, followed by Sales, followed by Accoutants. Config Managers/Sales to print to both printers, Accountants to only 1. Allow Sales/Mangers to print after the first page is spooled, Accountants only print after last page is spooled.
* Same Scenario as above, similar solution. Only major difference was that system was setup so Accounting group would print in off-peak hours.
* You're the admin of master domain and u want to create a global group that has right to backup all DC (mandatory) and member server/Workstations (optional).
*Proposed Solution: Create a global group called PrintGlobal in master, put them into
backup ops in resource domain. (This does not fulfill the Optional)
* Same Scenario as above: Proposed Solution was different. Create a global group called BackUpGlobal in Master, create BackUpLocal in each resource domain. assign BackUpGlobal to BackUpLocal, assign BackUpLocal backup/restore rights. Also, put BackUpGlobal groups in all member server/workstations local backup groups.
* Your designing several server roles. You have 5000 users accessing a SQL server. How would you config this server?
(Here you have a graphic with four options...)
1.???
2. Balanced
3. Maximize Throughput for File sharing
4. Maximize Throughput for Network access
* You have configed a server/printer with the DLC protocol, after you reboot, you can't print why?
Something about someone connected to the printer with a continuous connection
