You can use this service to adjust the advanced network settings of DHCP clients. The Distributed File System Replication DFSR service is a state-based, multi-master file replication engine that automatically copies updates to files and folders between computers that are participating in a common replication group.

It is not used on a Windows Server domain controller. The Distributed Link Tracking Server system service stores information so that files that are moved between volumes can be tracked to each volume in the domain. The Distributed Link Tracking Server service runs on each domain controller in a domain. This service enables the Distributed Link Tracking Client service to track linked documents that are moved to a location in another NTFS file system volume in the same domain.

The Distributed Transaction Coordinator DTC system service coordinates transactions that are distributed across multiple computer systems and resource managers, such as databases, message queues, file systems, or other transaction-protected resource managers.

DNS servers are required to locate devices and services that are identified by using DNS names and to locate domain controllers in Active Directory. The Event Log system service logs event messages that are generated by programs and by the Windows operating system. Event log reports contain information that you can use to diagnose problems. You view reports in Event Viewer. The Event Log service writes events that are sent to log files by programs, by services, and by the operating system.

The events contain diagnostic information in addition to errors that are specific to the source program, the service, or the component. This service has the same firewall requirements as the File and Printer Sharing feature.

Fax Service lets users use either a local fax device or a shared network fax device to send and receive faxes from their desktop programs. The File Replication service FRS is a file-based replication engine that automatically copies updates to files and folders between computers that are participating in a common FRS replica set.

FRS is the default replication engine that is used to replicate the contents of the SYSVOL folder between Windows based domain controllers and Windows Server based domain controllers that are located in a common domain. By default, the FTP control port is The default data that is used for active mode FTP port is automatically set to one port less than the control port. Therefore, if you configure the control port to port , the default data port is port This means that the client first connects to the FTP server by using the control port.

Then, the client opens a second connection to the FTP server for transferring data. You can configure the range of high ports by using the IIS metabase. If any one of these protocols is unavailable or blocked between the client and a relevant domain controller, Group Policy will not apply or update. For a cross-domain logon, where a computer is in one domain and the user account is in another domain, these protocols may be required for the client, the resource domain, and the account domain to communicate.

ICMP is used for slow link detection. When you initiate remote group policy results reporting from a Windows Server computer, access to the destination computer's event log is required. See the Event Log section in this article for port requirements. Windows Server support the initiation of remote group policy update against Windows Server computers. SSL is an open standard for establishing an encrypted communications channel to help prevent the interception of extremely important information, such as credit card numbers.

Although this service works on other Internet services, it is primarily used to enable encrypted electronic financial transactions on the World Wide Web WWW. Internet Authentication Service IAS performs centralized authentication, authorization, auditing, and accounting of users who are connecting to a network. 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.

There is a small,free utility available at that site which can open or close the port for you. Shunned , Mar 25, I don't use IE, but the Opera browser Strange stuff.
