Error reporting is enabled by default in Windows 7. You might want to disable error reporting for privacy concerns, if you're not connected to the Internet all the time, or maybe just to stop being annoyed by the alerts. Error reporting works by prompting you after a critical error in the Windows 7 operating system or in other programs and then notifying Microsoft about it. This way, Microsoft can gather technical information about serious errors from millions of PCs which helps them develop patches and service packs. See the easy steps below if you'd like to disable error reporting in Windows 7: Difficulty: Easy Time Required: Disabling error reporting in Windows 7 usually takes less than 5 minutes

In this section we see. · SNMP Architecture · SNMP Manager/Agent Communication · SNMP Management Systems and Agents · SNMP Messages Use Simple Network Management Protocol (SNMP) management software to monitor any network device configured with SNMP agent software. The SNMP agent, which is an optional component of Windows Server 2003, interacts with third-party SNMP management software to enable the flow of network status information between monitored devices and applications and the management systems that monitor them. You can use SNMP in environments that include large networks with hundreds or thousands of nodes that would otherwise be difficult and costly to monitor. SNMP allows monitoring of network devices such as servers, workstations, printers, routers, bridges, and hubs, as well as services such as Dynamic Host Configuration Protocol (DHCP) or Windows Internet Name Service (WINS). The following sections describe the architecture, components, and processes us...

Simple Network Management Protocol (SNMP) is a popular protocol for network management. It is used for collecting information from, and configuring, network devices, such as servers, printers, hubs, switches, and routers on an Internet Protocol (IP) network. Microsoft Windows Server 2003 provides SNMP agent software that works with third-party SNMP management software to monitor the status of managed devices and applications. Automating Network Management Large networks with hundreds or thousands of nodes are difficult to manage without a large staff to monitor every computer. SNMP, which is widely used in local area networks (LANs), lets you monitor network nodes from a management host. You can monitor network devices such as servers, workstations, printers, routers, bridges, and hubs, as well as services such as Dynamic Host Configuration Protocol (DHCP) or Windows Internet Name Service (WINS).

In Microsoft Windows Server 2003 network monitoring technologies help network administrators track and manage the functions of devices on the network. Network Monitoring Components There are two network monitoring technologies that help network administrators track and manage the functions of devices on the network: Simple Network Management Protocol (SNMP) SNMP is a network management protocol that can monitor and alert administrators regarding the condition of hardware components such as workstations and servers. Microsoft Computer Browser Service The Computer Browser Service in computers running Windows enables network administrators and users to browse and gain access to the resources of the network. The browser service provides a convenient listing of devices such as workstations and printers, and allows network users access to them with the proper authentication.

When the DHCP Server role is installed on a domain controller, the DHCP Server inherits the security permissions of the domain controller. To prevent possible misuse of the domain controller’s elevated permissions, DHCP Servers that are installed on Windows Server 2003 do not register DNS records on behalf of the clients that are associated with the DHCP Server unless the DHCP Server is explicitly configured with DNS credentials. This behavior prevents a potential escalation of privilege to clients of the DHCP Server. Configuring DNS credentials on a DHCP Server that is running Windows Server 2003 Follow these steps to configure the DNS credentials of a DHCP Server that is installed on a domain controller running the Windows Server 2003 operating system: Start the DHCP management console. Click Start , then click Run and type dhcpmgmt.msc . In the DHCP navigation pane, expand the server node and right-click IPv4 , and then click Properties . In...

Set Windows as Default OS in OS choice menu when Dual Booting Ubuntu & Windows When you install a dual-boot of Ubuntu, one of the frustrating things that you’ll immediately notice is that Ubuntu is now set as the default operating system in the Grub loader. There’s an easy way to switch back to using Windows as the default. To make this change, you’ll first have to boot into Ubuntu, and then run the following command: sudo gedit /boot/grub/menu.lst Find this section of the file: ## default num # Set the default entry to the entry number NUM. Numbering starts from 0, and # the entry number 0 is the default if the command is not used. # # You can specify ’saved’ instead of a number. In this case, the default entry # is the entry saved with the command ’savedefault’. # WARNING: If you are using dmraid do not change this entry to ’saved’ or your # array will desync and will not let you boot your system. default 0 The important line is the last...

Introduction This page describes how to set up your computer in order to dual boot Ubuntu and Windows. Back Up Your Data Although this may seem obvious, it is important to backup your data files to an external backup medium before attempting a dual-boot install (or any other hard drive manipulation), in case your hard drive becomes corrupted during the process. External hard drives, USB flash drives, and multiple DVDs or CDs are useful as external backup media. Have a Windows recovery CD/DVD available Many computer manufacturers that pre-install Windows provide a Windows recovery/re-installation CD or DVD with the computer. However, many companies no longer ship a physical disk but instead create a hidden partition on the hard drive in which the recovery-disk information is stored. A utility is then usually provided which allows the user to burn a recovery/re-installation CD or DVD from it. If you are buying a new computer and intent on dual-booting, make su...

The master servers for a stub zone are one or more DNS servers authoritative for the child zone, usually the DNS server hosting the primary zone for the delegated domain name. What does a DNS stub zone consists of? A stub zone consists of:  The start of authority   (SOA) resource record, name server (NS) resource records, and the glue A   resource records for the delegated zone.
