- 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 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, while the physical layer is reponsible for retrieving and sending raw data bits.
- 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.

Windows 2000 administration questions
- Explain hidden shares. Hidden or administrative shares are share names with a dollar sign ($) appended to their names. Administrative shares are usually created automatically for the root of each drive letter. They do not display in the network browse list.
- 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.

- How do you convert a drive from FAT/FAT32 to NTFS from the command line? convert c: /fs:ntfs
- 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.
- 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
Windows Server 2003 IIS and Scripting interview questions
- What is presentation layer responsible for in the OSI model? The presentation layer establishes the data format prior to passing it along to the network application’s interface. TCP/IP networks perform this task at the application layer.
- Does Windows Server 2003 support IPv6? Yes, run ipv6.exe from command line to disable it.
- Can Windows Server 2003 function as a bridge? Yes, and it’s a new feature for the 2003 product. You can combine several networks and devices connected via several adapters by enabling IP routing.
- What’s the difference between the basic disk and dynamic disk? The basic type contains partitions, extended partitions, logical drivers, and an assortment of static volumes; the dynamic type does not use partitions but dynamically manages volumes and provides advanced storage options
- What’s a media pool? It is any compilation of disks or tapes with the same administrative properties.
- How do you install recovery console? C:\i386\win32 /cmdcons, assuming that your Win server installation is on drive C.

- What’s the relation between SSL and TLS? Transport Layer Security (TLS) extends SSL by providing cryptographic authentication.
- What’s the role of http.sys in IIS? It is the point of contact for all incoming HTTP requests. It listens for requests and queues them until they are all processed, no more queues are available, or the Web server is shut down.
- Where’s ASP cache located on IIS 6.0? On disk, as opposed to memory, as it used to be in IIS 5.
- What is socket pooling? Non-blocking socket usage, introduced in IIS 6.0. More than one application can use a given socket.
- Describe the process of clustering with Windows 2003 Server when a new node is added. As a node goes online, it searches for other nodes to join by polling the designated internal network. In this way, all nodes are notified of the new node’s existence. If other nodes cannot be found on a preexisting cluster, the new node takes control of the quorum resources residing on the shared disk that contains state and configuration data.
- What applications are not capable of performing in Windows 2003 Server clusters? The ones written exclusively for NetBEUI and IPX.
- What’s a heartbeat? Communication processes between the nodes designed to ensure node’s health.
- What’s a threshold in clustered environment? The number of times a restart is attempted, when the node fails.
- You need to change and admin password on a clustered Windows box, but that requires rebooting the cluster, doesn’t it? No, it doesn’t. In 2003 environment you can do that via cluster.exe utility which does not require rebooting the entire cluster.
- For the document of size 1 MB, what size would you expect the index to be with Indexing Service? 150-300 KB, 15-30% is a reasonable expectation.
- Doesn’t the Indexing Service introduce a security flaw when allowing access to the index? No, because users can only view the indices of documents and folders that they have permissions for.
- What’s the typical size of the index? Less then 100K documents – up to 128 MB. More than that – 256+ MB.
- Which characters should be enclosed in quotes when searching the index? &, @, $, #, ^, ( ), and |.
- How would you search for C++? Just enter C++, since + is not a special character (and neither is C).
- What about Barnes&Noble? Should be searched for as Barnes’&’Noble.
- Are the searches case-sensitive? No.
- What’s the order of precedence of Boolean operators in Microsoft Windows 2003 Server Indexing Service? NOT, AND, NEAR, OR.
- What’s a vector space query? A multiple-word query where the weight can be assigned to each of the search words. For example, if you want to fight information on ‘black hole’, but would prefer to give more weight to the word hole, you can enter black hole into the search window.
- What’s a response queue? It’s the message queue that holds response messages sent from the receiving application to the sender.
- What’s MQPing used for? Testing Microsoft Message Queue services between the nodes on a network.

- How does HSRP work?
What is the significance of the IP address 255.255.255.255? – The limited broadcast address is utilized when an IP node must perform a one-to-everyone delivery on the local network but the network ID is unknownWindows Server and MS Exchange interview questions

- What would a rise in the Local Delivery queue generally mean? – This indicates a performance issue or outage on the local server. Reasons could be slowness in consulting AD, slowness in handing messages off to local delivery or SMTP delivery. It could also be databases being dismounted or a lack of disk space.
