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.
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).
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.
How can you force the client to give up the dhcp lease if you have access to the client PC?
ipconfig /release
What authentication options do Windows 2000 Servers have for remote clients?
PAP, SPAP, CHAP, MS-CHAP and EAP.
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).
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.
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.
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.
What is LMHOSTS file?
It’s a file stored on a host machine that is used to resolve NetBIOS to specific IP addresses.
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.
How can you recover a file encrypted using EFS?
Use the domain recovery agent.
What is the Difference between Windows 2003 standard Enterprise, Premium, Data center and Web Edition?
WEB EDITION:
To position windows server 2003 more competitively against other web servers, Microsoft has released a stripped-down-yet-impressive edition of windows server 2003 designed specially for web services. the feature set and licensing allows customers easy deployment of web pages, web sites, web applications and web services.
Web Edition supports 2GB of RAM and a two-way symmetric multiprocessor(SMP). It provides unlimited anonymous web connections but only 10 inbound server message block(SMB) connections, which should be more than enough for content
publishing. The server cannot be an internet gateway, DHCP or fax server. Although you can remotely administer the server with Remote Desktop, the server can not be a terminal
server in the traditional sense. The server can belong to a domain, but cannot be a domain controller. The included version of the microsoft SQL server database Engine can support as many as 25 concurrent connections.
How do you recover an object in Active Directory, which is accidentally deleted by you, with no backup?
Using ntdsutil.exe command,we can restored the AD objects.
What is the Logical / Physical Structures of the AD Environment?
physical structure:
Forest, Site, Domain, DC
logical structure:
Schema partition, configuration partition, domain partition and application partition
How to change the windows xp product key if wrongly installed with other product key but you have original product key? What you will do to Make your os as Genuine?
Some third party software are available for this function or reinstall this system
If 512mb Ram is there what will be the minimum and maximum Virtual memory for the system?
To workout the total virtual memory (page file) required for windows XP you should take the amount of ram in the system and + 25% (512MB + 25% (128MB) = 640MB total virtual memory. by setting both the min and max to 640MB you can increase the performances of the operating system.
What is LDAP?
LDAP, Lightweight Directory Access Protocol, is an Internet protocol that email and other programs use to look up information from a server.
What is the SYSVOL folder?
The Sysvol folder on a Windows domain controller is used to replicate file-based data among domain controllers. Because junctions are used within the Sysvol folder structure, Windows NT file system (NTFS) version 5.0 is required on domain controllers throughout a Windows distributed file system (DFS) forest.
What are application partitions? When do we use them?
Application Directory Partition is a partition space in Active Directory which an application can use to store that application specific data. This partition is then replicated only to some specific domain controllers.The application directory partition can contain any type of data except security principles (users, computers, groups).
How do we Backup Active Directory?
Backing up Active Directory is essential to maintain an Active Directory database. You can back up Active Directory by using the Graphical User Interface (GUI) and command-line tools that the Windows Server 2003 family provides.You frequently backup the system state data on domain controllers so that you can restore the most current data. By establishing a regular backup schedule, you have a better chance of recovering data when necessary.To ensure a good backup includes at least the system state data and contents of the system disk, you must be aware of thetombstone lifetime. By default, the tombstone is 60 days. Any backup older than 60 days is not a good backup. Plan to backup at least two domain controllers in each domain, one of at least one backup to enable anauthoritative restore of the data when necessary.
How do we restore AD?
You can’t restore Active Directory (AD) to a domain controller (DC) while the Directory Service (DS) is running. To restore AD, perform the following steps.
Reboot the computer.
The computer will boot into a special safe mode and won’t start the DS. Be aware that during this time the machine won’t act as a DC and won’t perform functions such as authentication.
1. Start NT Backup.
2. Select the Restore tab.
3. Select the backup media, and select System State.
4. Click Start Restore.
5. Click OK in the confirmation dialog box.
After you restore the backup, reboot the computer and start in normal mode to use the restored information. The computer might hang after the restore completes; I’ve experienced a 30-minute wait on some machines.
What are GPOs?
Group Policy gives you administrative control over users and computers in your network. By using Group Policy, you can define the state of a user’s work environment once, and then rely on Windows Server 2003 to continually force the Group Policy settings that you apply across an entire organization or to specific groups of users and computers.
What domain services are necessary for you to deploy the Windows Deployment Services on your network?
Windows Deployment Services requires that a DHCP server and a DNS server be installed in the domain
What is the difference between a basic and dynamic drive in theWindowsServer2008environment?
A basic disk embraces the MS-DOS disk structure; a basic disk can be divided into partitions (simple volumes).
Dynamic disks consist of a single partition that can be divided into any number of volumes. Dynamic disks also support Windows Server 2008 RAID implementations.
What is the main purpose of a DNS server?
DNS servers are used to resolve FQDN hostnames into IP addresses and vice versa
Commonly Used DNS Records?
A-Records (Host address)
CNAME-Records (Canonical name for an alias)
MX-Records (Mail exchange)
NS-Records (Authoritative name server)
PTR-Records (domain name pointer)
SOA-Records (Start of authority)
