2. How do the permissions work in Windows 2000? What permissions does folder inherit from the parent? When you combine NTFS permissions based on users and their group memberships, the least restrictive permissions take precedence. However, explicit Deny entries always override Allow entries.
3. Why can’t I encrypt a compressed file on Windows 2000? You can either compress it or encrypt it, but not both.
4. If I rename an account, what must I do to make sure the renamed account has the same permissions as the original one? Nothing, it’s all maintained automatically.
5. What’s the most powerful group on a Windows system? Administrators.
6. What are the accessibility features in Windows 2000? StickyKeys, FilterKeys Narrator, Magnifier, and On-Screen Keyboard.
7. Why can’t I get to the Fax Service Management console? You can only see it if a fax had been installed.

9. How do you configure mandatory profiles? Rename ntuser.dat to ntuser.man
10. I can’t get multiple displays to work in Windows 2000. Multiple displays have to use peripheral connection interface (PCI) or Accelerated Graphics Port (AGP) port devices to work properly with Windows 2000.
11. What’s a maximum number of processors Win2k supports? 2
12. I had some NTFS volumes under my Windows NT installation. What happened to NTFS after Win 2k installation? It got upgraded to NTFS 5.
13. How do you convert a drive from FAT/FAT32 to NTFS from the command line? convert c: /fs:ntfs
14. Explain APIPA. Auto Private IP Addressing (APIPA) takes effect on Windows 2000 Professional computers if no DHCP server can be contacted. APIPA assigns the computer an IP address within the range of 169.254.0.0 through 169.254.255.254 with a subnet mask of 255.255.0.0.
15. How does Internet Connection Sharing work on Windows 2000? Internet Connection Sharing (ICS) uses the DHCP Allocator service to assign dynamic IP addresses to clients on the LAN within the range of 192.168.0.2 through 192.168.0.254. In addition, the DNS Proxy service becomes enabled when you implement ICS.
16. | Describe how the DHCP lease is obtained. It’s a four-step process consisting of (a) IP request, (b) IP offer, © IP selection and (d) acknowledgement.
17. I can’t seem to access the Internet, don’t have any access to the corporate network and on ipconfig my address is 169.254.*.*. What happened? The 169.254.*.* netmask is assigned to Windows machines running 98/2000/XP if the DHCP server is not available. The name for the technology is APIPA (Automatic Private Internet Protocol Addressing).
18. We’ve installed a new Windows-based DHCP server, however, the users do not seem to be getting DHCP leases off of it. The server must be authorized first with the Active Directory.
19. How can you force the client to give up the dhcp lease if you have access to the client PC? ipconfig /release
1)What authentication options do Windows 2000 Servers have for remote clients? PAP, SPAP, CHAP, MS-CHAP and EAP.
2)What are the networking protocol options for the Windows clients if for some reason you do not want to use TCP/IP? NWLink (Novell), NetBEUI, AppleTalk (Apple).
3) What is binding order? The order by which the network protocols are used for client-server communications. The most frequently used protocols should be at the top.
4)How do cryptography-based keys ensure the validity of data transferred across the network? Each IP packet is assigned a checksum, so if the checksums do not match on both receiving and transmitting ends, the data was modified or corrupted.
5)Should we deploy IPSEC-based security or certificate-based security? They are really two different technologies. IPSec secures the TCP/IP communication and protects the integrity of the packets. Certificate-based security ensures the validity of authenticated clients and servers.
6)What is LMHOSTS file? It’s a file stored on a host machine that is used to resolve NetBIOS to specific IP addresses.
7)What’s the difference between forward lookup and reverse lookup in DNS? Forward lookup is name-to-address, the reverse lookup is address-to-name.
8)How can you recover a file encrypted using EFS?
Use the domain recovery agent.
9)Can't enable guest account
A:To enable guest account on w2k/xp, you must logon as administrator.
10))Cannot add a new local user
A:Cause: you are using domain credentials to add a new user on a computer that doesn’t connect to the domain.
11)How Inheritance Affects File and Folder Permissions
A:After you set permissions on a parent folder, new files and subfolders that are created in the folder inherit these permissions. If you do not want the files and folders to inherit permissions, click This folder only in the Apply onto box when you set up special permissions for the parent folder. If you want to prevent only certain files or subfolders from inheriting permissions, right-click the file or subfolder, click Properties, click the Security tab, click Advanced, and then click to clear the Inherit from parent the permission entries that apply to child objects. Include these with entries explicitly defined here check box.
12)If the check boxes are not available, the file or folder has inherited permissions from the parent folder. There are three ways to make changes to inherited permissions:
Make the changes to the parent folder so that the file or folder inherits the permissions.
Click to select the opposite permission (Allow or Deny) to override the inherited permission.
Click to clear the Inherit from parent the permission entries that apply to child objects. Include these with entries explicitly defined here check box. When you do this, you can make changes to the permissions or remove the user or group from the permissions list. However, the file or folder does not inherit permissions from the parent folder.
13)How to access Domain Console without logon the domain
A:Sample issue: I have group policy that is locking down the computer for ALL User, Even the administrator. Now I cant access the domain network from any computers
Solution: Logon as the administrator with the same password of the domain administrator. Then access the AD Users and Computers-Connected to the domain controller. Moved the admin accounts up to the Users OU.
14)How to check the group policy settings and result
A:You can use gpresult.exe which displays the resulting set of policies that were forced on the client for the specified user at logon.1.
15)How to manage inherited permissions
A:By default, Everyone has Full Control for a NTFS folder and the permission is inherited from the root folder on the partition or volume. To block Permissions Inheritance, click to clear the Allow inheritable permissions from parent to propagate to this object check box.
16)How to change the password policy
A:For local computer, go to Local Computer Policy>Computer Configuration>Windows Settings>Security Settings>Account Policies>Password Policy. For domain controller, go to Default Domain Security Setting>Security Settings>Account Policies>Password Policy.
17)How to protect my computer without buying hardware or software firewall?

A:Symptom: Your WinXP, in a peer-to-peer mixed network, may receive the following error when you double-click My Network Places/Computers Near Me:
Resolution: 1) Enable NetBIOS over TCP/IP on one or more computers in the workgroup. To do that, go to properties of Local Area Connection>properties of Internet Protocol (TCP/IP)>General> Advanced>WINS, check Enable NetBIOS over TCP/IP (If you have a DHCP-assigned IP address, select Use NetBIOS setting from the DHCP server ). 2) Make sure the Computer Browser service is started.
22)The password does not meet the password policy requirement
A:Symptoms: when attempting to create a new account with a password or change the password on 2003 server and the member of computers, you may receive this messages "Windows cannot complete the password change. The password does not meet the password policy requirement. Check the minimum password length, password complexity and password history requirement".
Cause: The default minimum password length is 7 and the password must meet complexity requirement on 2003 domain controller. By default, member of computers follow the password configuration of the their domain controller.
23)The Sharing tab is not visible
A:The sharing tab is not visible if you are logged on to a machine with an account that does not have adequate rights.
24)Understand Allow and Deny permissions
A: 1) Allow permissions are cumulative, so a user's permissions are determined by the cumulative effect of all of the groups to which the user belongs. 2) Deny permissions override Allow permissions. Use caution when you apply Deny permissions.
25)Why can't I have permission button while setup sharing on XP
A:The reason you can't see the permission is because the XP simple file sharing is enabled. To disable simple file sharing, go to windows explorer>tools>folder options>view, uncheck use simple file sharing. Just remember that, after disabling simple file sharing, some users may have
difficulty to access the sharing folders.

Resolution: enable file and printer sharing.
71)Can't net view computer name - error 52
Symptoms: you can ping a host but not net view it. When using net view \\hostname, you get system error 52 - a duplicate name exists on the network.
Resolutions: there are two host names or alias name (cname) are pointed to the same IP. 1) check the WINS records. 2) check DNS records.
72)Can't ping or net view computer name - error 53
Symptom: if you can ping IP but not computer name, or if you can net view \\IP but not \\computername (error 53). You have name resolution problem.
Resolutions: 1) if it is domain environment, check your WINS. 2) if it is peer-to-peer workgroup, enable NetBIOS over TCP/IP. 3) or add NetBEUI on all your workstations.
Troubleshooting Ping
73)Can't ping another computer because of the ICF
Sometimes, XP's built-in Firewall may enable after running network setup wizard on LAN connections. You can't ping or access the XP computer. To disable the XP firewall on the connection, go to the properties of the Connections, select Advanced, and deselect the firewall.
74)Can't ping outside IP or name
If you can't ping outside IP, make sure you have correct gateway. If you can't ping outside computer name or web name, check the DNS settings.
75)Can't use ping
If you cannot use ping successfully at any point, confirm that:
1)The computer was restarted after TCP/IP was configured.
2) The IP address of the local computer is valid and appears correctly on ipconfig /all.
3) IP routing is enabled and the link between routers is operational.
4) For the security reasons, many organizations block the return of ICMP (ping) packets so that ping or tracert may not be possible to obtain a response.
76)Error code 65, 10043 and 10050, transmit failed
Symptoms: When using ping command, you may receive either of the following: "Transmit failed, error code 65" or "Transmit failed, error code 10050"
Resolutions: make sure your firewall, NAT or router doesn't disable ping and to allow ICMP Echo and Echo Reply packets.
77)Hardware Error
Symptom: when you try to ping an IP, you may receive "hardware error" reply.
Causes: 1. Bad NIC.
2. The cable doesn't plug in.
78)Host is unreachable
Q: When I ping the server using one of the clients it says the host is unreachable. Why?
A: 1) Make sure all machines are on the same local subnet and no routers in between.
2) Check the lmhosts file to make sure that you do not have an outdated file.
79)Ping lists a public IP instead of private IP
Symptom: when you ping a LAN computer like ping chicagotechpc1, you may receive a public ip 64.176.153.103 instead of the computer private IP 192.168.1.100.
Cause: Incorrect DNS settings. For consultants, refer to case 060104RL
80)Receiving a reply from a different IP
Symptoms: when you ping a public IP, you may receive reply from a different IP, for example,
ping 4.2.2.1
Pinging 4.2.2.1 with 32 bytes of data:
Reply from 209.165.105.129: Destination net unreachable.
Causes: If you have incorrect IPSec settings, you may have above mentioned symptom.
81)Cannot view event log after changing administrator password
A:Symptoms: After you changed the administrator password on a 2003 server, you are unable to access some server information like the event logs.
Cause: When using Reset Password on Local Users and Groups, that may cause irreversible loss of information. You should use Ctrl+Alt+Del instead of Reset Password to change administrator password.
82) How do cryptography-based keys ensure the validity of data transferred across the network?
Ans:Each IP packet is assigned a checksum, so if the checksums do not match on both receiving and transmitting ends, the data was modified or corrupted.
83) Should we deploy IPSEC-based security or certificate-based security?
Ans:They are really two different technologies. IPSec secures the TCP/IP communication and protects the integrity of the packets. Certificate-based security ensures the validity of authenticated clients and servers.
84) What is LMHOSTS file?
Ans: It’s a file stored on a host machine that is used to resolve NetBIOS to specific IP addresses.
85) What authentication options do Windows 2000 Servers have for remote clients?
Ans: PAP, SPAP, CHAP, MS-CHAP and EAP.
86)AD communication, including replication, fails on multihomed domain controllers
A:Cause: network adapters on the multihued domain controllers are registering both the inside and outside Internet Protocol (IP) addresses with the DNS server. Replication operations require multiple lookup requests of SRV records. In this case, half of the DNS lookup requests return an IP address that cannot be contacted, and the replication operation fails.
87) Tracert
A:Tracert.exe is a route-tracing utility that you can use to determine the network path to a destination. To determine the path that a packet takes on the network and where that path may be ending.
88)NBTSTAT
A:Nbtstat.exe is a useful tool for troubleshooting NetBIOS name resolution problems. You can use the nbtstat.exe command to remove or correct preloaded entries.
Viewing configuration by using ipconfig /all or winipcfgl
Refreshing configuration by using ipconfig /renew
Managing DNS and DHCP class IDs by using ipconfig
Testing connections by using ping
Troubleshooting hardware addresses by using arp
Troubleshooting NetBIOS names by using nbtstat
Displaying connection statistics by using netstat
Tracing network connections by using tracert
Testing routers by using pathping
Viewing configuration by using ipconfig /all or winipcfg
89)Name 3 differences between Windows 2000 Standard and Windows 2000 Advanced
90))In reference to Windows 2000 DNS, what are resource records -better known as SRV records?
91))What is the current service pack for Windows 2000?
92))Where would I go in Windows 2000 to find out more information in reference to a
service not starting?
Active Directory Services:-
93) If I have 2 servers one at Mumbai & one at U.K on which server u
will place the Global Catlog?

mode?
95) which dialer you are using in your company?
96) why we get disturbance in IPLC?
97). Broadcast is in which range of IP range?
98) how many IP u can give on 1 LAN card?
99) whats the difference between Router & switch?
100) Can i give the IP starting from 163. in my LAN? If yes then Why? If noThen Why?
101)What is “REGEDIT” ?
102)Port Numbers for the following:-
1)HTTP-80
2)DNS -53
3)POP3-110
4)SMTP-25
5)TCP/IP-6
6)FTP-21
7)DHCP
103) What does PING stand for? What are the error messages in PING command? What does TTL stand for? On which layer does PING work? Which is the protocol that PING uses?
A:A utility to determine whether a specific IP address is accessible. It works by sending a packet to the specified address and waiting for a reply. PING is used primarily to troubleshoot Internet connections. There are many freeware and shareware Ping utilities available for personal computers.
It is often believed that "Ping" is an abbreviation for Packet Internet Groper, but Ping's author has stated that the names come from the sound that sonar makes.
Time to Live- length of time to get the packet returned.
104)What is data link layer in the OSI reference model responsible for? Data link layer is located above the physical layer, but below the network layer. Taking raw data bits and packaging them into frames. The network layer will be responsible for addressing the frames, The physical layer is responsible for retrieving and sending raw data bits.
105) What is a level 0 backup?
106) What is an incremental backup?
