Not soon after servers have started recovering from WannaCry ransomware, there is this new Petya ransomware which spreads rapidly to Windows servers via the networks.
Once infected, the Petya ransomware locks up your entire server files and encrypts them in such a way that you can no longer use them. The attackers then demand $300 Bitcoins as ransom to decrypt your data.
WannaCry ransomware is all over the news now, causing the internet world to shake in doubt and fear. With over 200,000 computers in 150 countries being affected, the damage is really wide-spread.
For businesses and servers that are affected by this malware, the impact of this attack is huge and can lead to loss of business. As a result, it is important to secure your servers for ensuring their normal functioning. (more…)

DHCP is a protocol that is designed to reduce the complexity that is involved in IP address allocation. Consider an organization having, say, 20 computers. In this case, it is easily possible for an administrator to specify the IP addresses, default gateways and DNS servers. However, in the case of a corporate network having more than 300 machines, it’s definitely not an easy job to allocate all the parameters to all the machines on the network.
This is where the advantage of DHCP comes in. It totally removes this over head for system administrators and helps to automate the entire process.
For this, you first need to configure a DHCP server on your network. In Windows 2003, this process is simple and requires only an hour of administrative work.
The DHCP sever will assign an IP address that is taken from a predefined scope, for a specified amount of time. If a client requires an IP address, longer than the lease period, they must request an extension before the lease expires. Otherwise that IP address is considered free and would be assigned to another client.
Consider a business organization that has its facilities spread across the country or around the world. There is one thing that it will need – a way to maintain fast, secure and reliable communication amongst all its branches. There are also many organizations which require their employees to access the network remotely, when they are on any on-site work. This way, the employees are able to access the network resources, as they are connected to the network of the company.
Until recently, the only choice available to the administrators was to use leased lines to maintain a WAN, which provides reliability, performance and security. However, this was not a very feasible solution, as maintaining a WAN is quite expensive. And the expenses increase with distance between the offices.
An alternative came in the form of Virtual Private Networks. A VPN is a private network that utilizes a public network (Internet) to connect remote sites or users together. Thus, instead of dedicated leased lines, a VPN uses a secure virtual connection, which is routed through the Internet, connecting remote sites or users to the network.
Windows is a self tuning operating system. It’s kernel is already optimized to work in a variety of scenarios. There are only limited operations that can be performed to optimize the system.
The benefits associated with such a system include:
Server Administration becomes easy.
There are less chances of damaging the system by fiddling with the kernel level.
Performance Analysis is more of an art than a science. This article mainly focuses on familiarizing the readers with Performance Console also known as System Monitor Tool, by explaining some technical terms that are associated with it. Towards the end of the article, four major Subsystems that affect the performance of the system are also explained.
The boot process starts when you turn on your computer and ends when you log on to Windows Server 2003. There can be various reasons for startup failures. Some can be easily corrected, while others might require you to reinstall Windows Server 2003.
This article will help you understand and troubleshoot most of the errors commonly occurring during the Windows Server 2003 boot process. (more…)
