Windows Clustering and Load Balancing, Explained
Monday, March 16th, 2009 | Author:

Clustering in Windows 2003 Dedicated or Shared hosting is a means of providing High Availability to your applications and websites. Clustering is a group of machines acting as a single entity to provide resources and services to the network. In time of failure, a fail over will occur to a system in that group that will maintain availability of those resources to the network. You can be alerted to the failure, repair the system failure, and bring the system back online to participate as a provider of services once more. You learn about many forms of Windows clustering. Clustering in Windows 2003 hosting can allow for failover to other systems and it can also allow for load balancing between systems. Load balancing in Windows 2003 hosting is using a device, which can be a server or an appliance, to balance the load of traffic across multiple servers waiting to receive that traffic. The device sends incoming traffic based on an algorithm to the most underused machine or spreads the traffic out evenly among all machines that are on at the time. A good example of using this technology would be if you had a web site that received 2,000 hits per day. If, in the months of November and December, your hit count tripled, you might be unable to sustain that type of increased load. Your customers might experience time outs,

Thursday, March 12th, 2009 | Author:

Some times Configuring MSDTC and their error can ruin your Windows Cluster service and your time as well. You may get one of the following error when you failover the MSDTC service from one Dedicated node to another.

This would only happen if the Cluster services has been installed before installing and configuring MSDTC Service. Hence it is highly recommended that you first install and configure MSDTC and then configure the Windows Cluster Service.

Check list for Remote Desktop not Working
Wednesday, March 11th, 2009 | Author:

Remote Desktop [RDP] not Working..?

This applies to all versions of Windows 2003 and Windows 2008 and also to Vista and XP Professional. This problem normally occurs to our client with Dedicated Server hosting. So I thought I will create a check list to make their hosting service a bit easy.
Yes, you will need physical access to the machine to check this, it is obvious that you will not be able to check this problem unless you have remote access to the server. These steps can only be performed if you have physical access to the dedicated server or through a Keyboard-Video-Mouse [KVM]. So there we go:

* First thing that you need to check is whether the Remote Desktop Console [RDC] is enabled on your server.
Go to Desktop >> My Computer >> Properties >> Remote Tab
Check the box for “Enable Remote Desktop on this computer” and click OK.

How to Block IP on Windows.
Friday, February 27th, 2009 | Author:

It is very easy to block a single IP address on a Linux server but Windows Default firewall doesn’t allow us to block a single IP address on the server or for particular ports. However Microsoft released this and introduced IP Security Polices in their Local Security Polices option in the release of their SP2. But most of us are not aware of this option and we mostly adopted third party firewall and pay for their heavy license. However Firewall onl Windows 2008 Server is far more advanced than that on Windows 2003.

It would not be the case now as I have listed detailed steps along with the images on how to block IP using the IP security policy in Windows. This option is also available in XP as well as Windows 2003 Server edition.

How to BLock IP Using Windows:

You can either open MMC from START >> RUN >> MMC and add a new Snapin for IP Security policy with steps below:

Group Policies Overview for SQL Server
Friday, February 27th, 2009 | Author:

Group Policy is a core part of Microsoft’s IntelliMirror technology.You can use Group Policy to manage all aspects of the Server environment for Windows Server, including Registry settings, software installation, scripts, security settings, and so on.The possibilities of what can be done with Group Policy are almost limitless.With VBScript or Jscript, you can write entire applications to execute via Group Policy.You can install software automatically across the network and apply patches to applications. When deciding on the Group Policies you plan to enforce on your network, you should keep in mind that the more policies applied, the more network traffic, and hence the longer it could take for users to log onto the network. Group policies are stored in Active Directory as Group Policy Objects (GPO).These objects are the instructions for the management task to perform. Group Policy is implemented in four ways:

PROCEDURE TO MAKE CDONTS WORK ON A WINDOWS 2003 SERVER

Microsoft Windows Server 2003 does not install Collaboration Data Objects (CDO) for
NTS (CDONTS). Therefore, applications that use   do not function on a Windows
Server 2003-based computer.

Windows Server 2003 provides improved alternatives to CDONTS. To make CDONTS

When you first learn about ‘Remote Desktop‘ and ‘Remote Assistance‘, you might easily make it out that both services are the same. They allow you to remotely control a PC from any where, let it be on your local network or even over the Internet. Although there are some important differences that we need to check between these two services.

1] Remote Assistance uses Windows XP/2003 Terminal Services to share desktop and other resources between two PCs.

Terminal Services - It is a way of using RDP (Remote Desktop Protocol), which allows users to connect to their Windows XP desktop or a dedicated server (Terminal Server) combining with VPN (Virtual Private Network) with the help of which users can connect to their office network remotely and work with their applications.

Virtual Private Network – Creates a secure connection between private networks.

In a *Remote Assistance Session* -

Both users must be present at their respective PCs and must agree to establish a connection.
