You may receive the following message when you connect your 2000 or 2003 server from other computer on the network.

a)Error = There are currently no logon servers available to service the logon request.
This error you’ll get from Windows NT Server 4.0-based computer.

b)Error =Server name is not accessible. The logon server cannot be found.
This is the error you’ll get from Windows 98-based computer.

The Windows server 2000 or 2003 is logged on to the domain and connects everything on the network but the computer cannot contact the domain controller is shown by the event viewer. The computer is logged on to the domain through cached credentials which is reported by Netdiag utility.

Solution:
To solve this problem join the windows 2003 server to workgroup named WORKGROUP and then restart the computer. Rejoin the computer to the domain and restart the computer again. The computer doesn’t log on through cached credentials then.

Hello,

For anyone trying to get the cheapest internet available, there are tons of options available. Some providers offer completely free service. But the trade-off is permanent pop ups along the bottom of your desktop, or other advertiser gimmicks that may inhibit your Internet experience.

But if you are living in the U.K. and want broadband service at its very cheapest, there are a few companies you should consider first.
First off would be Homecall Broadband. Homecall has voice and data bundled packages starting at just 19.99 pounds. These deals include 2 mbps in bandwidth, and the company always seems to be running specials too. For cheap Internet access and, as a bonus, solid broadband service, Homecall is someone worth checking out.
Wanadoo Broadband is another U.K. company to look at if you are looking for cheap broadband. The company also offers a 2 mbps deal that starts at 17.99 pounds. The deals also go up depending on how light or heavy a user you are. Wanadoo also offers a free modem and connection from time to time, a 50 pound value. Wanadoo also offers a six months free program for qualifying members.
BT Broadband is another U.K. firm that is becoming increasingly popular with its cheap Internet offerings. What BT offers deals from 26.99 pounds per month, and also has a variety of packages available for home or business.
Like anything, finding the cheap Internet access is not too hard. But doing a little research to find the most reliable and suitable product for your needs may be what’s important. There are a number of cheap Internet providers. But it may be best to talk to a few people who use their service to find out if they are reliable or not.
Also, look at your personal needs. Don’t let yourself get sold up into a package that is more than what you need. Figure out what you need first, and then shop for that when you are looking to find a cheap Internet provider. One aspect of finding cheap Internet access knows if you are using it for home or office. If you have a small business that relies heavily on your computers, the cheapest may not always be the best option for you.
With competition for Internet users by Internet providers becoming more and fiercer every day, it can be said that cheap Internet access is more a buyer’s market. There are a number of providers who are willing to cut their rates or match the competitors’ prices to get your business. Anyone looking for cheap Internet access should know this before they start doing research. After that, you can look at who is offering the cheapest service with decent quality and use them as a barometer when shopping around.
All the best.

FDDI is an abbreviation for Fiber Distributed Data Interface. It’s a set of ANSI and ISO standards for transmitting data on fiber optic cables in a local area network(LAN) at a rate of around 100,000,000 bits-per-second. The LAN range can extend upto 200kms and the data transmission is 10 times as fast as ethernet, and about twice as fast as T-3. The FDDI protocol is based on the Token Ring protocol.

In addition to it being large geographically, an FDDI local area network can support thousands of users. FDDI networks are typically used as backbones for wide-area networks.

An FDDI network contains two token rings, The primary ring offers up to 100 Mbps capacity and the secondary ring is for possible backup in case the primary ring fails. If the secondary ring is not needed for backup, it can be used to carry data, extending the capacity to 200 Mbps. The single ring can extend the maximum distance; a dual ring can extend for 100 km.

An extension to FDDI, called FDDI-2, supports the transmission of voice and video information as well as data. Another variation of FDDI, called FDDT - Full Duplex Technology uses the same network infrastructure but can potentially support data rates up to 200 Mbps.

Token Ring is a type of computer network in which all the computers are connected in a star or ring topology. A token, which is a special bit pattern, travels around the circle. To send a message, a computer catches the token, attaches a message if it has one to send, and then lets the token go to continue around the ring. A token ring can be wired as a circle or a star, with the workstations wired to a central wiring center, or to multiple wiring centers.

In a Token Ring network, each computer is constantly in direct contact with the next node in the ring but a Token Ring network cannot communicate within itself if any one of the rings is broken.

The token ring network architecture was developed by IBM and later standardized as the IEEE 802.5 standard and is the second most widely-used protocol on local area networks after Ethernet.

BITNET is short form for Because It’s Time Network. BITNET is one of the oldest and largest major wide-area networks, used extensively by universities and other academic and research computer networks to store and forward messages that are sent between users. This system was often used before the Internet was developed, but today its use is limited.

BITNET isn’t truly a part of the Internet as it is not based on the TCP/IP protocols that Internet networks generally use. BITNET users can send and receive electronic mails to and from the Internet, due to gateways that act as “translators” between the different network protocols.

Other non-TCP/IP networks are also linked to the Internet using a mixture of gateways, but more commonly, the sites on BITNET and other networks that don’t do TCP/IP are switching to networks with capabilities of talking in the TCP/IP language so that they can fully utilize the resources of the Internet. The popularity and use of BITNET seems to be on a decline and its numbers of sites and users is reducing as sites manage to connect directly to the Internet.

There’s also a new version of BITNET, called BITNET-II, which relies on the Internet network to transfer messages and files.

Peer-to-peer network is a communications network that allows all computers in the network to act as servers and share their files with all other users on the network. On the Internet, peer-to-peer network is a type of transient Internet network that allows a group of computer users with the same networking program to connect with each other and directly access files from one another’s hard drives. Peer to Peer networks also referred to as P2P networks are generally used for connecting nodes via largely distinct connections. Such networks are useful for many purposes like sharing content files containing audio, video, data or anything in digital format is very common, and realtime data, such as telephony traffic, is also passed using P2P technology.
