Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base: How to back up and restore the registry in Windows. Verify that the cluster node that is having problems is able to properly authenticate the Service account.
You can determine this by logging on to the computer with the Cluster service account, or by checking the System event log for Cluster service logon problem event messages. Start Registry Editor Regedt The cluster hive should have a structure that is very similar to Cluster Administrator.
Make note of the network and quorum keys. If the database isn't valid, you can copy and use the cluster database from a live node. If the node isn't the first node in the cluster, check connectivity to other cluster nodes across all available networks. Please provide additional feedback optional :.
Cancel Submit. You are using Microsoft Internet Explorer! Microsoft no longer supports this browser. These users can be on a LAN connection or on a remote connection. This system service provides NAT, addressing, and name resolution services for all computers on your home network or your small-office network. When the Internet Connection Sharing feature is enabled, your computer becomes an Internet gateway on the network. Other client computers can then share one connection to the Internet, such as a dial-up connection or a broadband connection.
They do not provide these services on the external network interface. When you use the Kerberos Key Distribution Center KDC system service, users can sign in to the network by using the Kerberos version 5 authentication protocol.
As in other implementations of the Kerberos protocol, the KDC is a single process that provides two services: the Authentication Service and the Ticket-Granting Service. The Authentication Service issues ticket granting tickets, and the Ticket-Granting Service issues tickets for connection to computers in its own domain.
The License Logging system service is a tool that was originally designed to help customers manage licenses for Microsoft server products that are licensed in the server client access license CAL model. By default, the License Logging service is disabled in Windows Server Because of legacy design constraints and evolving license terms and conditions, License Logging may not provide an accurate view of the total number of CALs that are purchased compared to the total number of CALs that are used on a particular server or across the enterprise.
License Logging is not included in Windows Server and later operating systems. We recommend that only users of the Microsoft Small Business Server family of operating systems enable this service on their servers.
The Message Queuing system service is a messaging infrastructure and development tool for creating distributed messaging programs for Windows. These programs can communicate across heterogeneous networks and can send messages between computers that may be temporarily unable to connect to one another. Message Queuing helps provide security, efficient routing, support for sending messages within transactions, priority-based messaging, and guaranteed message delivery.
The Microsoft POP3 service provides email transfer and retrieval services. Administrators can use this service to store and manage email accounts on the mail server. When you install POP3 service on the mail server, users can connect to the mail server and can retrieve email messages by using an email client that supports the POP3 protocol, such as Microsoft Outlook.
The Net Logon system service maintains a security channel between your computer and the domain controller to authenticate users and services. It passes the user's credentials to a domain controller and returns the domain security identifiers and the user rights for the user. This is typically known as pass-through authentication. Net Logon is configured to start automatically only when a member computer or domain controller is joined to a domain. The NetMeeting Remote Desktop Sharing system service allows authorized users to use Windows NetMeeting to remotely access your Windows desktop from another personal computer over a corporate intranet.
You must explicitly enable this service in NetMeeting. You can disable or shut down this feature by using an icon that is displayed in the Windows notification area. Clients can use a news client, such as Microsoft Outlook Express, to retrieve newsgroups from the server and to read the headers or the bodies of the articles in each newsgroup.
Offline Files and Roaming User Profiles cache user data to computers for offline use. These capabilities exist in all supported Microsoft operating systems.
All of these systems use SMB. Folder Redirection redirects user data from the local computer to a remote file share, using SMB. Primary Computer provides a capability to prevent data caching to computers that are not authorized by administrators for specific users. This system was added in Windows Server The Performance Logs and Alerts system service collects performance data from local or remote computers based on preconfigured schedule parameters and then writes that data to a log or triggers a message.
Based on the information that is contained in the named log collection setting, the Performance Logs and Alerts service starts and stops each named performance data collection.
This service runs only if at least one performance data collection is scheduled. The Print Spooler system service manages all local and network print queues and controls all print jobs. Print Spooler is the center of the Windows printing subsystem. The Remote Procedure Call RPC system service is an interprocess communication IPC mechanism that enables data exchange and invocation of functionality that is located in a different process.
Many services depend on the RPC service to start successfully. By default, this service is turned off. The Remote Storage Notification system service notifies users when they read from or write to files that are available only from a secondary storage media. Stopping this service prevents this notification. The Remote Storage system service stores infrequently used files on a secondary storage medium. If you stop this service, users cannot move or retrieve files from the secondary storage media.
Although the Routing and Remote Access service can use all the following protocols, the service typically uses only a few of them. For example, if you configure a VPN gateway that is behind a filtering router, you will probably use only one protocol. For more information about this, see the References section. The Server system service provides RPC support and file sharing, print sharing, and named pipe sharing over the network. The Server service lets users share local resources, such as disks and printers, so that other users on the network can access them.
It also enables named pipe communication between programs that are running on the local computer and on other computers. Named pipe communication is memory that is reserved for the output of one process to be used as input for another process. The input-accepting process does not have to be local to the computer. Preloaded Lmhosts entries will bypass the DNS resolver. Windows and newer clients can work over port The SharePoint Portal Server system service lets you develop an intelligent portal that seamlessly connects users, teams, and knowledge.
It helps people take advantage of relevant information across business processes. Microsoft SharePoint Portal Server provides an enterprise business solution that integrates information from various systems into one solution through single sign-on and enterprise application integration capabilities. It accepts and queues email messages for remote destinations, and it retries at set intervals. Windows domain controllers use the SMTP service for intersite e-mail-based replication.
SNMP Service includes agents that monitor activity in network devices and report to the network console workstation. After the user attaches a debugger to the resource monitor process, and the resource monitor process starts up, the Cluster service continues with its initialization. NoRepEvtLogging Function: The norepevtlogging switch prevents replication of those events recorded in the event log. This switch is useful in reducing the amount of information displayed in the command window by filtering out events already recorded in the event log.
Event log replication is a feature that was added in Windows Usage scenarios: This switch is used to prevent replication of the event logs. If there is a large number of event log entries, the Cluster service will replicate these, and log these to the cluster. This can cause the cluster. The switch can also be used to start the Cluster service and log those events that are not recorded in the event log to a local file, Debugnorep. The command-line syntax is:.
NoQuorumLogging Function: Turns off all logging of the cluster registry changes to the quorum disk. Registry check pointing does not effect other resources. Requirements: This switch must be used only in diagnosis mode to diagnose problems with the quorum log file Quolog. If one node is started up by using this switch, any other node must also be started up by using this switch.
Typically, this switch is used on one node alone. Usage scenarios: Use this switch when the quorum log file or checkpoint files become corrupted and you want to manually replace these files with backup copies. Operation: The Cluster service completely bypasses the logging functionality in this case. When run in this mode, "partition-in-time" scenarios can occur. If this is the case, cluster node registry entries can fall out of synchronization, and new changes can be lost.
ForceQuorum Function: When you use a Majority Node Set MNS quorum model on a Windows Server cluster, in some cases a cluster must be allowed to continue to run even if it does not have "quorum" majority.
While there are no failures, the cluster is a seven-node cluster where resources can be hosted on any node, on any site. If there is a communications failure between the sites or if the secondary site is taken offline or fails , the primary site can continue because it will still have quorum.
All resources will be re-hosted and brought online at the primary site. In the event of a catastrophic failure of the primary site, however, the secondary site will lose quorum, and, therefore, all resources will be terminated at that site. One of the primary purposes for having a multi-site cluster is to survive a disaster at the primary site; however, the cluster software itself cannot make a determination about the state of the primary site.
The cluster software cannot differentiate between a communications failure between the sites and a disaster at the primary site. That must be done by manual intervention.
In other words, the secondary site can be forced to continue even though the Cluster service believes it does not have quorum. This is known as forcing quorum. Because this mechanism is effectively breaking the semantics associated with the quorum replica set, it must only be done under controlled conditions.
In the example above, if the secondary site and primary site lose communication and an administrator forces quorum at the secondary site, resources will be brought online at BOTH sites, thus allowing the potential for inconsistent data or data corruption in the cluster.
Requirements: Forcing quorum is a manual process that requires that you stop the Cluster service on ALL the remaining nodes. The Cluster service must be told which nodes should be considered as having quorum. Usage scenarios: Special care must be taken if and when the primary site comes back because the nodes are configured as part of the cluster.
