System Diary. November 13, Three network components are listed:. All three of these are described in Chapter 3. This is the protocol we will be manually configuring in this chapter. Directly under the list of network components are three buttons: Install, Uninstall, and Properties. Click the Install button to install a network component. Three component types are offered:. A client component is the client side of some network service. The Client for Microsoft Networks component described above is one example.
A service component is the server side of a network service. A protocol component is a network communications protocol. Of course, the client and service components also contain protocol elements, so the distinction is somewhat arbitrary. By default, the Select Network Protocol window offers the following five protocol component selections:.
This is the IPv6 protocol described in Chapter 2. The Uninstall button removes an unneeded network component. To remove a component, simply highlight the component name in the list box and click Uninstall. You will be asked to verify the removal.
Click Yes and the network component is removed. The Properties button is used to configure a protocol. Protocol configuration is the principal topic of this chapter. This tab is used to manually define the basic configuration or to select automatic configuration from the DHCP server. DHCP is a key component of a manageable, reliable, and efficient network. Despite the label on this option button, it does much more than just obtain the IP address automatically. Of course, as the administrator of the network it is your responsibility to set up the DHCP server as described in Chapter 5.
But your work relieves end users of configuration responsibilities and reduces the number of user configuration errors that you have to fix. The configuration steps described in the next section are not needed for the majority of systems on a network that uses DHCP. Below are the manual configuration fields on the IP address portion of the General tab:. Enter a valid IP address for this computer, using dotted decimal format.
This is a single address from your address range. Enter the appropriate subnet mask, again using dotted decimal format. By default, this field will use the natural mask for the address entered above. If you subnet, you should place your subnet mask here.
If you do not subnet, use the prefix-length assigned with the address block to determine the mask. Chapter 2 covers subnets and address masks. Enter the IP address for the default router in dotted decimal format. Chapter 2 provides background on routing and the use of default gateways, and there is more on routing and gateways later in this chapter.
Of course, before manually entering data into any of these fields you must know exactly what you are going to enter. The network administrator is responsible for making and communicating decisions about overall network configuration.
If you are creating a new network, you will have to make some basic decisions. One of these decisions is how to choose a network number for your new network, which is the topic of the next section. If you already have IP addresses for your network, you can skip this section.
First, you must decide how many hosts on a new network will be fully accessible from the Internet. Many new networks attach to the Internet indirectly so that access into the new network from other Internet networks is limited.
Users on the new network can access remote Internet hosts but remote users cannot directly access all of the hosts on the indirectly connected network. Because the hosts on this network are not accessible to users in the outside world, they do not require public IP addresses.
Only the subset of systems exposed to the outside world requires public IP addresses. Therefore, the network administrator of this network can select a network address from RFC , Address Allocation for Private Internets. The private network numbers are The pros and cons of using a network address from RFC are covered in Chapter 2 , where private network numbers are discussed in detail. But, in general, if you can use a private network number, you should. Some organizations choose to give every device on the network an address that will make that device fully accessible from the Internet.
A network that wants to be fully accessible from all sites on the Internet must obtain a public network address to allow outside users direct access into the systems on your network. An official address is needed for every system on the network that is directly accessible to remote Internet hosts.
Every network that communicates with the Internet, even those that use NAT, has at least one public address, although that address may be assigned to the NAT box.
To make many or all of the systems on your network accessible, you need a block of addresses. The first step toward obtaining a block of addresses is to determine how many addresses you need. A small- to medium-sized organization focused on connecting itself to the Internet. What categorizes this organizational type is that it wants to use the Internet while limiting the number of systems it makes available to remote users.
From the point of view of the Internet, all Internet end-user organizations appear small because they use only a limited number of official addresses. A medium- to large-sized organization that distributes official addresses to systems throughout its network. This type of organization tends to have a distributed management under which divisions within the overall organization are allowed to make systems remotely accessible.
High-volume end-user organizations usually satisfy their address requirements through their ISP or a Local Internet Registry. If the organization needs more than 8, addresses, it may go directly to a Regional Internet Registry. While in reality a high-volume end-user organization may not be any larger than an Internet end-user organization, it appears to be larger from the point of view of the Internet because it exposes more systems to the Internet.
An organization that provides Internet connection services to other organizations and provides those organizations with official addresses. Even an ISP connects to the Internet in some way. The upstream provider assigns addresses to the ISP. An organization that provides addresses to ISPs. In effect a Local Internet Registry is an organization that provides addresses to other organizations that provide addresses.
RFC lists four organizational types in order to be thorough. Most organizations are either Internet end users or high-volume end users. In all likelihood, your organization is one of these, and you will obtain all of your addresses from your ISP.
Your ISP has been delegated authority over a group of network addresses and should be able to assign you a network number. Ask your local ISP whom it receives service from and ask that organization for an address. If all else fails, you may be forced to go directly to an Internet registry. If you are forced to take your request to a registry, you will need to take certain steps before you make the application.
You need to prepare a detailed network topology. The topology must include a diagram that shows the physical layout of your network and highlights its connections to the Internet. You should include network engineering plans that, in addition to diagramming the topology, describe:. Your routing plans, including the protocols you will use and any constraints that forced your routing decisions.
Your subnetting plans, including the mask you will use, and the number of networks and hosts you will have connected during the next year. The biggest challenge is accurately predicting future requirements for addresses.
If you have previously been assigned an address block, you may be required to provide a history of how that address block was used. Even if it is not requested by the Internet registry, a history can be a helpful tool for your own planning. Additionally, you will be asked to prepare a network deployment plan. This plan typically shows the number of hosts you currently have that need official addresses and the number you expect to have in six months, one year and two years.
One factor used to determine how much address space is needed is the expected utilization rate. The expected utilization rate is the number of hosts assigned official addresses divided by the total number of hosts possible for the network. The deployment plans must show the number of hosts that will be assigned addresses over a two-year period. The total number of possible hosts can be estimated from the total number of employees in your organization and the number of systems that have been traditionally deployed per employee.
Clearly you need to have a global knowledge of your organization and its needs before applying for an official address assignment. In addition to providing documentation that justifies the address request, obtaining an official address requires a formal commitment of resources. Most address applications require at least two contacts: an administrative contact and a technical contact.
The administrative contact should have the authority to deal with administrative issues ranging from policy violations to billing disputes. The technical contact must be a skilled technical person who can deal with technical problems and answer technical questions.
Internet registries require that these contacts live in the same country as the organization that they represent. You must provide the names, addresses, telephone numbers, and email addresses of these people. These are not honorary positions. These people have targets on their backs when things go wrong. In addition to human resources, you need to commit computer resources. It is essentially the computer object and has more permissions than necessary.
The recommendation I recall for SQL Server was that you should configure a domain user account to run the service. The account should have only the permissions necessary for the service. The only documentation I could quickly find:. Was your dc recently promoted, and perhaps the problem started after that?
Since the network service account is essentially the local system, maybe forcing a password change would help. One recommendation I remember for sure; Never run dcpromo either to promote to a dc or to demote to a member server on a computer with SQL Server installed.
I'm with problem like this, a service 'microsoft exchange transport' don't up with account 'network service', that I did for resolve this was put this account 'network service' in administrators group, so it can up, I tried do this procedure clock syncronization that you sad, but don't work,.
Does it happen in your case? When a service fails to start an error is logged to the Event Log. What error do you get regarding the Microsoft Exchange Transport service? Office Office Exchange Server. Not an IT pro? Expand your skills. Get new features first.
