 Hardware Condition

 Line Condition


Port

The COM port the current connection is using.

Server

The name of the active server.


Modem Condition

If the value is not Normal, a hardware failure has occurred and the modem or serial port may be damaged.


Line Condition

Helps you determine if an unauthorized user is attempting to access your network.


Port Speed (bps)

The speed in bits per second (bps) at which data is being transferred between the port and the modem.


Incoming:

Bytes

The number of characters sent from the Remote Access client to the Remote Access server since the connection was established or since you clicked the Reset button.

Frames

The number of logical network frames received from the client. The format of the frame depends on the network protocol in use. The maximum size of a frame is 1514 bytes. Well-written client/server applications transmit a small number of full or almost full frames. If you observe large numbers of small frames, the application you are running was probably not designed to run efficiently across slow links.


Compression

The ratio of compression achieved on received data, where higher is better. For example, if 400 incoming bytes decompress into 1,000 bytes, the compression ratio is 60 percent. This value refers to software compression only. The compression ratio depends on the amount of redundancy in the data received. For example, text and bitmaps compress well, but executable files and previously compressed data do not.

Connections using IP protocol VJ header compression (if active) is figured into this number. This entry may be non-zero even when Disable Software Compression (which applies only to data, not headers) is selected.

Note  Software compression is not attempted on some frames, for example, multicast datagrams or very small frames. Such frames are not included in the compression computation.


Outgoing:

Bytes

The number of characters sent from the Remote Access server to the Remote Access client since the connection was established or since you clicked the Reset button.

Frames

The number of logical network frames sent to the client. The format of the frame depends on the network protocol in use. The maximum size of a frame is 1514 bytes. Well-written client/server applications transmit a small number of full or almost full frames. If you observe large numbers of small frames, the application you are running was probably not designed to run efficiently across slow links.


Compression

The ratio of compression achieved on transmitted data, where higher is better. For example, if 1,000 bytes are compressed into 400 bytes before transmission, the compression ratio is 60 percent. This value refers to software compression only. The compression ratio depends on the amount of redundancy in the data being transmitted. For example, text and bitmaps compress well, but executable files and previously compressed data do not.

Connections using IP protocol VJ header compression (if active) is figured into this number. This entry may be non-zero even when Disable Software Compression (which applies only to data, not headers) is selected.

Note  Software compression is not attempted on some frames, for example, multicast datagrams or very small frames. Such frames are not included in the compression computation.


CRC

Errors caused by the failure of a cyclic redundancy check (CRC). A CRC error indicates that one or more characters in the data packet arrived garbled from the server.


Timeouts

A condition in which an expected character is not received in time. When this condition occurs, the software assumes that the data has been lost and requests that it be resent.


Alignment

A condition in which a character received is not the one expected. An alignment error usually happens when a character is lost or when a timeout error occurs.


Framing

An error in which an asynchronous character is received with an invalid start or stop bit. If this error occurs and the computer is unable to establish a Remote Access connection, the computer to modem (DCE to DTE) bps rate may be incorrect. This problem suggests that the modem configured for Remote Access may not be the correct one for the modem you're using. Changing the bps rate or the hardware flow control setting may alleviate the problem. Contact your system administrator if this error occurs continually and if you are unable to connect through Remote Access.


Remote Workstations

The name or network address of the remote client connected to this port.


Hardware Overruns

The number of times the sending computer has transmitted characters faster than the receiving computer can process at the hardware level. If this problem persists, reduce the bps rate.


Buffer Overruns

The number of times the sending computer has transmitted characters faster than the receiving computer can process at the software level. If this problem persists, reduce the bps rate or lower the CPU load on the computer.


Resets the statistics for this connection to zero.

Data Overruns

The number of times the sending computer has transmitted characters faster than the receiving computer can process at the hardware level. If this problem persists, reduce the bps rate.


Hardware Condition

If the value on the Port Status dialog box is not Normal, a hardware failure has occurred and the modem or serial port may be damaged. The following table shows the possible values for this field:

Value	Meaning
Normal	No errors have been detected on the modem. The modem is operating normally.
Modem not responding	The modem is not responding. Make sure that the modem has been turned on and is properly connected to the serial port.
Hardware failure	An unknown error has occurred. The modem or serial port may be damaged.
Incorrect modem response	The modem has responded with an unknown error. You may be using a modem that is not supported by Remote Access, or your modem configuration file may be corrupted. Contact your system administrator to ensure that your modem is supported by Remote Access. If you are using a supported modem, reinstall the Remote Access software.
Internal error	An internal software error has occurred. Restart Remote Access or restart your computer.


Line Condition

The value on the Port Status dialog box helps you determine if an unauthorized user is attempting to access your network. The following table shows the possible values for this field:

Value	Meaning
Waiting for call	Remote Access has put the modem in Listen mode and is waiting for incoming calls. The modem is operating normally.
Connected, user authenticating	A telephone connection has been established. The user may be trying to be authenticated by the Remote Access server, or may be idle. If you get this condition followed by the waiting-for-call phase, then the user was unable to provide a correct user name, password, and/or domain name. If you repeatedly get this phase followed by the waiting-for-call phase, an unauthorized attempt to access your network may be under way.
Connected, user authenticated	A telephone connection has been established and the user has entered a correct user name and password. If the user has callback permission and has requested callback, the connection is followed by the calling-back phase. If the calling-back phase is followed by a waiting-for-call phase, then the server was not able to reach the user at the specified number. The user may have provided an inaccurate callback number (in the case of Set by Caller callback), or an unauthorized attempt to access your network may be under way (in the case of Preset To callback).
Calling back	The Remote Access server has determined that the user has a valid Windows NT user account, Remote Access permission, and callback permission. The Remote Access server is now calling the user back.
Line non-operational	The modem and/or serial port is not working. Make sure your modem has been turned on and is properly connected to the serial port.

Troubleshooting

Backward Compatibility

For backward compatibility, the Remote Access servers, version 1.1 or earlier, should contain the following minimal configuration.

LANMAN.INI File

[remoteaccess]

MaxNames=8	;For extra NetBIOS names on

;Windows NT workstations.

remotelisten=all	;Enables the peer capabilities of

;Windows NT workstations

;through the Remote Access server.

PROTOCOL.INI File

[netbeui_xif]

sessions=160

ncbs=180

name=160

[tcpip_xif]

nbsessions=100

;numnames=85	;Commenting out the numnames

;line lets the TCP/IP stack

;assume the highest value possible.

If servers with earlier versions of the Remote Access Server do not have this minimal configuration, Windows NT-based workstations will get the following error message when dialing in: "Server name table full."


X.25 Network

An X.25 network transmits data with a packet-switching protocol, bypassing noisy telephone lines. You can access an X.25 network in two ways:

Method of access	Server / Client
Asynchronous PADs	Client (Windows NT)
Direct connection	Server (Windows NT and Windows NT Advanced Server) and client (Windows NT)

ISDN Wide Area Network

 ISDN Overview

 Installing an ISDN Card


ISDN Overview

Integrated Services Digital Network (ISDN) offers a much faster communication speed than a telephone line. The phone line communicates at 9600 bits per second (bps), whereas ISDN communicates at speeds of 64 or 128 kilobits per second. Businesses that need this kind of speed usually have a large telecommuting work force or need to do extensive administrative tasks remotely, such as install software on off-site workstations.

The Remote Access Service sees ISDN as a combination of the following:

Serial port

ISDN card connected to the port

See Also

 Installing an ISDN Card


Installing ISDN
Installing an ISDN Card

An ISDN line comes with two B channels and one D channel. Each B channel transmits data at 64 kilobits per second. The D channel is for signaling and transmits data at 16 kilobits per second.

Install ISDN cards on the server and on each client. (For instructions, see the card's documentation.) Then configure each B channel to act as a port, or configure all B channels to act as a single port.

If your business has a large number of people calling in to the Remote Access server, configure each channel to operate as a port. This configuration allows the greatest number of people to call in.

However, if your business has few people calling in, but needs more data-transmission speed, configure both channels to act as a single port. With this configuration, line speed increases to 128 kilobits per second. If you have installed more than one card, you can combine the channels on each card and get even faster transmission speed.

To configure the ISDN card to work with the Remote Access Service, see online help for the Remote Access Phone Book.
