Windows Server 2003 is one of the latest operating systems which is built on the base of the most powerful, stable and popular (formerly) Windows 2000’s kernel. Undoubtedly Server 2003 has much more power, speed and stability that its “ancestor”.
So in comparison to Windows 2000 and Windows NT4.0, Windows Server 2003 has the following features improved: 1. Active Directory improvement: NT4.0 did not have this feature because it was introduced only in 2000 series. This technology allows “it easy for users to locate resources on even the largest networks”. In Server 2003 it is completely integrated and additionally allows renaming domains, editing attributes and classes in the schema. 2. Group Policies improvement: NT4.0 did not have this feature also. Group policies allow to define the settings and permissions for different users. It is much better than local policies because of its flexibility and ability to work with separate elements of Active directory. 3. Resultant Set of Policy: in order to ease and control work of system administrators this feature allows to check out how group policies work relatively separate users or groups. 4. Volume Shadow Copy Restore: this technology makes reserve copies of data on the server and thus secures data from accidental deletion or critical damage without service interruption. 5. Internet Information Services updated: completely rebuilt and based on new algorithms this feature enables Web Services and applications. Each application works in a separate pool now and thus failures of separate pools do not affect the performance of the whole server. There is a good monitoring of pools ability which helps to determine and eliminate the reasons of the failures. 6. Integrated .NET Framework: “takes care of the integration and management details, reducing code complexity and increasing coherency”.
7. Clustering: this technology joins several nodes (servers) to work as one. So far if one of the servers crashes while performing a critical operation (printing, messaging or working with a database) the other one continues this operation until it is finished. Windows Server 2003 Enterprise and DataCenter editions provide up to eight nodes. 8. Secure Wireless LAN: this feature secures any network activities, encrypting data stream and prevents unauthorized access to the system. 9. Emergency Management Services: this technology allows system administrators to manage computers under extreme conditions such as computers without monitor, mouse or keyboard etc.
Of course these are the main advantages of Server 2003 operating system and are not the only. In general Windows Server 2003 system works better with files and folders, networks, Web Services and provides a dramatic increase of system performance. I strongly recommend to upgrade current operating systems to Windows Server 2003 DataCenter in order to improve overall company’s performance and ease everyday operations of the personnel and receive all the features of this system.

Essentials of Supply Chain Management
The well-structured, easy-to-read book “Essentials of Supply Chain Management” written by Michael Hugos is a perfect introduction into supply chain management. It clearly tells about the most important concepts of supply chain management.
The effects of supply chain integration on supply chain capabilities
Nowadays, managers emphasize that functional capabilities - new-product development, manufacturing, technology, marketing - are enablers for success, but are no longer sources of competitive advantages, because they can all be replicated in time.
