Troubleshooting Group Policy Using Event Logs Sept. 28, 2018, 8:53 a.m.

Most of the events in the Group Policy operational log appear in pairs. For each start event, there is an end event. End events can be successful, warning, or error events. Usually these events share the last two digits in their event ids. For example, a 4017 event appears in the event log, which represents a Group Policy component beginning a specific action. If the action completes successfully, then the Group Policy service records a 5017 event. If the action completes with errors or fails then the Group Policy service records a 6017 or 7017 event, respectively. Policy processing events use the same numbering scheme for warning and error events messages in the 8000–8007 range for Group Policy success events. You can use these numbering patterns to quickly identify warning and failure events in the Group Policy operational log.

But, yes normally there is a but as well Smile the first CSE to be applied is {35378EAC-683F-11D2-A89A-00C04FBBCFA2}, this is the one for Registry/Administrative Templates this also includes if you write an ADMX template on your own, this will be applied first.

Borg, Omega, and Kubernetes July 31, 2018, 8:53 a.m.

Though widespread interest in software containers is a relatively recent phenomenon, at Google we have been managing Linux containers at scale for more than ten years and built three different containermanagement systems in that time. Each system was heavily influenced by its predecessors, even though they were developed for different reasons. This article describes the lessons we’ve learned from developing and operating them.

Connect to SQL Server When System Administrators Are Locked Out July 19, 2018, 2:15 p.m.

Start the instance of SQL Server in single-user mode by using either the -m or -f options. Any member of the computer's local Administrators group can then connect to the instance of SQL Server as a member of the sysadmin fixed server role.

Should I leave now? We look at Auckland Traffic Data June 28, 2018, 9:04 a.m.

There is a linear relationship between the time you want to leave and how busy the traffic will be at the time. If you normally leave your house at 7am and you are planning to leave at 7.30am, this will add another 10 minutes to your total travel time. So, every half an hour is equivalent to 10 minutes additional travel time when getting into the city in the morning hours, and leaving the city in the afternoon.

Non-functional requirement - Wikipedia May 6, 2018, 8:08 p.m.

In systems engineering and requirements engineering, a non-functional requirement is a requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviours. They are contrasted with functional requirements that define specific behaviour or functions.

DNS requirements for installing Active Directory April 16, 2018, 2:44 p.m.

When you install Active Directory on a member server, the member server is promoted to a domain controller. Active Directory uses DNS as the location mechanism for domain controllers, enabling computers on the network to obtain IP addresses of domain controllers.

During the installation of Active Directory, the service (SRV) and address (A) resource records are dynamically registered in DNS, which are necessary for the successful functionality of the domain controller locator (Locator) mechanism.

How DNS Support for Active Directory Works: Active Directory April 16, 2018, 2:44 p.m.

Active Directory uses DNS as its domain controller location mechanism and leverages the namespace design of DNS in the design of Active Directory domain names. As a result, DNS is positioned within the discoverability and logical structure components of Active Directory technology components.

An introduction to services, runlevels, and rc.d scripts April 13, 2018, 8:28 a.m.

A symlink, /etc/rc2.d/S91apache2, points to /etc/init.d/apache2. This tells init to start Apache 2 in runlevel 2, but only after other services with lower S numbers.

When the system is shut down, there is another symlink in the /etc/rc0.d and /etc/rc6.d directories (halt and reboot, respectively) that starts with a K instead of an S, which tells init to shut down the process.

CentOS Wiki - IPTables April 12, 2018, 8:46 a.m.

Iptables places rules into predefined chains - INPUT, OUTPUT and FORWARD - that are checked against any network traffic relevant to those chains and a decision is made about what to do with each packet based upon the outcome of those rules. These actions are referred to as targets, of which the two most common predefined targets are DROP and ACCEPT.

  • INPUT - All packets destined for the host computer.
  • OUTPUT - All packets originating from the host computer.
  • FORWARD - All packets neither destined for nor originating from the host computer, but passing through (routed by) the host computer. This chain is used if you are using your computer as a router.

Repeated characters when typing in VMware remote console April 12, 2018, 8:41 a.m.

If you are using a wide-area or low-bandwidth connection, the time delay over the network may be long enough to cause the virtual machine to start auto-repeat. To reduce these effects, increase the time threshold necessary for auto-repeat in the remote console by setting keyboard.typematicMinDelay = "2000000" in the virtual machine's configuration (.vmx) file.
