• You have installed Basic windows server 2003 installation

• Make sure you have assigned a static ip address to your server

Now start DC and DNS Setup process

1. Go to Start–>All Programs–>Administrative Tools–>Manage Your Server

2. Select Add or remove a role and Domain Controller (Active Directory) as the role and click Next

3. Next window select the default option of “Domain Controller for a new domain” and click “Next”

4. Create a domain in a new forest, because it is the first DC, so keep that option selected

5. Give a full DNS name for the new domain. (i.e. PBO.com)

6. Give a NetBIOS name of the domain.

7. The next dialog suggests storing the AD database and log on separate hard disks and you can just leave the default settings.

8. Next Screen basically says that you will need a DNS server in order for everything to work the way we want it. We will install the DNS server on this machine or if you want you can installed else where select “Install and Configure…” and click next.

9. On the next window you need to select the permissions for win 2000 or win 2003 server if you have any NT4 select first option otherwise select second option and click next.

10 The restore mode password is the single password that all administrators hope to never use, however they should also never forget it because this is the single password that might save a failed server.click Next.

1. Go to  Start–>All Programs–>Administrative Tools–>Manage Your Server

2. Select Add or remove roles

3.  Click Next and Select Server Role as DHCP Server option and click on Next again until the ‘New Scope Wizard’ window pops up.

4. Enter the name and description of your scope and click next. (A scope is a collection of IP addresses for computers on a subnet that use DHCP.)

5. Now you need to define the range of addresses that the scope will distribute across the network,the subnet mask for the IP address . Enter the appropriate details and click next.

6. Next you can enter the IP addresses to exclude.

7. Select lease duration how long a client can use an IP address assigned to it from this scope. It is recommended to add longer leases for a fixed network (in the office for example) and shorter leases for remote connections or laptop computers and click Next.

8. You are given a choice of whether or not you wish to configure the DHCP options for the scope now or later.You can select Yes,I want to… radion button and click Next.

9. Enter the router, or gateway, IP address click Next. The client computers will then know which router to use and click Next

10. Enter the DNS and domain name settings can be entered. The DNS server IP address will be distributed by the DHCP server and given to the client click Next

Configuring DHCP

1. Go to Start—>Administrative Tools—>DHCP

2. Right Click on your server click on Authorize your DHCP Server

Start Manage Your Server by clicking Start->Programs->Administrative Tools->Manage Your Server.

This will start the Configure Your Server Wizard. Read the text and make sure you have connected all the necessary cables and all the other things it says you should do before continuing.

Click next and select the server role and click next again. You will now specify the type of authentication and type the email domain name. And then next it and finish the wizard.

2. Configure the Email Server

• Click Start, then run, and type p3server.msc

This will open up the POP3 Service. This is where you configure and manage the POP3 part of the mail server.

• Click on <ComputerName> in the left pane
• Click on Server Properties in the right pane

Fact Sheet:

The standard port for the POP3 protocol is 110. If you change this, make sure you notify all users so they can configure their email clients to use this other port. Also make sure you restart the POP3 service if you change this.

3. Create a mailbox

The Setup Wizard created a domain to us, so we do not need to create this manually. If you did not use Manage Your Server to install, add the domain manually be clicking the server name in the left pane and then click New domain in the right pane. Remember to set the properties before you add the domain.

• Click on your domain in the left pane.
• Click Add Mailbox in the right pane.

4. Configure the SMTP Server

• Open Computer Management
• Expand Services and Applications, expand Internet Information Service
• Right click Default SMTP Virtual Server and click Properties
• Click the Access tab
• Click the Authentication button and make sure Anonymous Access and Integrated Windows Authentication is enabled.
• Click the Relay button and make sure Allow all computers which successfully… is enabled and Only the list below is selected.

First of all, Authentication and Relay is not the same thing. We use the Authentication button to specify which authentications methods are allowed for users and other SMTP servers. So enabling Anonymous here is not a security issue, in fact, it’s required if we want our server to be able to receive emails from other servers on Internet (I doubt you want to tell all administrators of email servers on Internet how they should logon to yours). We also need Windows Authentication so the email clients can authenticate to the server and be able to relay (send emails).

As Relay Restrictions we selected Only the list below because we do not want to be used by spammers to send emails. But we never specified any computers. That is valid, because we want our clients to always use the username and password to authenticate, no matter where they are.

If you want users to only be allowed to relay if they are on a private network, then you can uncheck Windows Authentication as allowed authentication method, and specify the IP range for your network in the Relay Restrictions window.

5. Configure the email client

You can use a e mail client such as Outlook.

Make sure all the devices are plugged in and only swapping is required. One of the most important devices when it comes to a internet utilizing network is your router. Routers are very expensive devices, rarely breaks down. The second most important device is the switch. Make sure to have several backup switches.

In case you can also plugging your wireless router to a switch and enable internet connection to part of the LAN network. But still you will be using the available bandwidth but dynamic IP’s could be assigned. Having a DHCP server comes in handy, for example if an ISP is down you can automatically assign IP’s from an up and running ISP. Still dedicated lines are not 100% reliable. Ups and downs may occur time to time and therefore balancing the load is very important.

Backups are very important for servers which function 24*7. If you are having a domain server and if the domain server breaks down the whole network could break down.

You can use a process called load balancing to spread the application load across two or more servers. This prevents one server from becoming overloaded while another is loafing. Load balancing works on the principle that if a server is busy or unavailable, a client connection is routed to the next available server. Normally it takes about 5 seconds to identify the situation and about 10 seconds to connect. Another fault tolerant feature available in Windows 2003  is clustering. Clustering is an advanced feature that allows the workload to be switched over from one server to another, either manually, or because of a hardware or software failure.

1. First, close ALL open programs, including any running in the background, like your anti-virus program, etc.

2. Search all files or folders. (Make sure you tick select hidden files, search sub folders, search system folders)

3. Now copy this *.tmp,*.chk,~*.* and paste it on the search box.

4. Now delete the temporary files.

For this I had to add some windows components. IIS is not installed as a default component. You can do this by:

Control Panel> Add/Remove programs > Click Add/Remove  Windows components  tab and tick IIS. Before you proceed make sure to click the detail tab and enable FTP services. The installation will ask for the XP CD.

You can use the Microsoft Management Console (MMC) Internet Information Services snap-in to configure the FTP service.

After the snap-in starts, expand the computer name, then expand FTP Sites. A Default FTP Site will have been added. Right-click Default FTP Site, then select Properties from the displayed context menu to set options such as Home Directory, accounts, and anonymous access. To stop the FTP service, right-click the FTP site and select Stop from the context menu; likewise, select Start from the context menu to restart the service.

The default FTP site is actually located in C:\Inetpub\ftproot. You can drop in some files and checkout this.

Now you will need a FTP client to access this directory. I used Filezilla. So now I have an up and running FTP server on your local computer. But I faced some problems, which I would like to share with you. If you can’t upload files and the client software gives a critical error message, make sure you enable read write and access. This can be done by right clicking on the virtual directory and going to properties.

The default configurations automatically enables anonymous access. This means than anyone who has your IP could access your files. Note that only the admin could make changes to your files.

Configure The FTP Service

// To configure the FTP Service to allow only anonymous connections, follow these steps:

1. Start Internet Information Services Manager or open the IIS snap-in.
2. Expand Server_name, where Server_name is the name of the server.
3. Expand FTP Sites
4. Right-click Default FTP Site, and then click Properties.
5. Click the Security Accounts tab.
6. Click to select the Allow Anonymous Connections check box (if it is not already selected), and then click to select the Allow only anonymous connections check box.

   When you click to select the Allow only anonymous connections check box, you configure the FTP Service to allow only anonymous connections. Users cannot log on by using user names and passwords.

7. Click the Home Directory tab.
8. Click to select the Read and Log visits check boxes (if they are not already selected), and then click to clear the Write check box (if it is not already cleared).
9. Click OK.
10. Quit Internet Information Services Manager or close the IIS snap-in.

The FTP server is now configured to accept incoming FTP requests. Copy or move the files that you want to make available to the FTP publishing folder for access.

The default folder is drive:\Inetpub\Ftproot, where drive is the drive on which IIS is installed.

Jitter is the variation of time between packets arriving. This could be caused by network congestion, timing drift, or route changes. A jitter buffer can be used to handle jitter. Some of the causes could be electromagnetic interference (EMI) and crosstalk with other signals.

Qos is the ability of the ISP to provide a constant stream of data without fluctuations. This is very important for Voip, most of the ISP’s would ignore this factor. You may notice that the maximum download speed shown is more than the connection speed rated by your ISP. This is usually due to how your connection is regulated. For example, an ISP may supply a 10 Mbit connection by allowing 100 Mbit for 10ms, and pause for 90ms.
The higher the download speed, the better, but a quality connection will also demonstrate very little fluctuation in download speeds.

TCP pause graph: Data is sent across the Internet in “blocks”. Usually a connection will send a block of data and pause before sending the next. (This pause is known as the TCP pause.) If the pauses become excessive it means that the connection throughput is being degraded.
A good connection will have both a low TCP pause (less than 20 ms), and also demonstrate very little fluctuation in the TCP pause values. This in essence defines a quality of data as it defines how much of the test time was spent actually transmitting data versus being idle waiting for data to arrive.

Now you got your reasons to nail your ISP……..

First use a good software to do the online tests.

Right click My Computer > Properties > Click Computer Name tab > Click Network ID tab and follow the Wizard.  Make sure you give the same work group name.  And thereafter you should enable Computer Browser service and NetBIOS.

Method 1: Enable NetBIOS over TCP/IP and start the Computer Browser service

// To resolve this issue, make sure that NetBIOS over TCP/IP is turned on and that the Computer Browser service is running on each computer in the workgroup. To do this, follow these steps.

Step 1: Enable NetBIOS over TCP/IP

//

1. Click Start, click Control Panel, and then click Network and Internet Connections. (Run > ncpa.cpl)
2. Click Network Connections.
3. Right-click Local Area Connection, and then click Properties.
4. Click Internet Protocol (TCP/IP), and then click Properties.
5. Click the General tab, and then click Advanced.
6. Click the WINS tab.
7. Under NetBIOS setting, click Enable NetBIOS over TCP/IP, and then click OK two times.
8. Click Close to close the Local Area Connection Properties dialog box.
9. Close the Network Connections window.

Step 2: Start the Computer Browser service

//

1. Click Start, right-click My Computer, and then click Manage.
2. Double-click Services and Applications.
3. Double-click Services.
4. On the right side, right-click Computer Browser, and then click Start.
5. Close the Computer Management window.

Step 3: Make sure PC’s are in the same workgroup.

Right click My Computer > Properties > Click Computer Name tab > Change Tab

Step 4: Share folders

Right click on folder > Sharing and security > Sharing Tab

Step 5: Map Network drives from remote PC

Go to My Computer > Tools > Map Network Drives > Browse your work group > browse your Shared folder > Select and click OK.

Method 2: By giving a secondary IP

First make sure to turn off simple file sharing and other applications that block your connection. (Firewalls). And also note that PC’s need to have static IP addresses.

Go to tools > folder options > view tab and un-check the simple file sharing.

Step 1: Giving a secondary IP

This need to be done in both host and remote PC’s.

Right click Local area connection > Properties > Select TCP/IP > Properties > Click advanced tab > Add a secondary IP (Something like 192.168.4.3)

Step 2: Share the drives

Right click the driver > Sharing and security > Click the Sharing tab and give a share name followed by the ‘$’ sign.

Step 3: Connecting to the PC

Run > \\IP \[driver name]$ – Ex: \\192.168.4.17\c$

Follow these steps to connect your computer to your wireless network:

1. Right-click the wireless network icon in the lower-right corner of your screen, and then click View Available Wireless Networks. If you run into any problems, consult the documentation that came with your network adapter. Don’t be afraid to call their tech support.
2. The Wireless Network Connection window should appear and you should see your wireless network listed with the network name you chose. If you don’t see your network, click Refresh network list in the upper-left corner. Click your network, and then click Connect in the lower-right corner.
3. Windows XP prompts you to enter a key. Type the encryption key that you wrote down earlier in both the Network key and Confirm network key boxes, and then click Connect.
4. Windows XP will show its progress as it connects to your network. After you’re connected, you can now close the Wireless Network Connection window. You’re done.

Note: If the Wireless Network Connection window continues to show Acquiring Network Address, you may have mistyped the encryption key.
