For example, your connection is requesting a TCP/IP address from the server that is not usable.contact your system administrator to verify the TCP/IP settings on your server. 717 No IP addresses are available in the static pool of remote access service IP addresses 717 Try to use an IP address that does not cause a conflict on the remote network. If possible, use DHCP to avoid addressing conflicts. See To configure TCP/IP settings. 718 The connection timed out waiting for a valid response from the remote computer 718 A PPP conversation started, but terminated because the remote computer did not respond within an appropriate time. This may be caused by poor line quality or by a problem at the server.

13 Page 13 of The connection was terminated by the remote computer 719 A PPP conversation started, but terminated at the request of the remote computer. An error probably occurred on the server. 720 The connection attempt failed because your computer and the remote computer could not agree on PPP control protocols 720 Either there are no PPP network control protocols configured for your connection, or the corresponding network protocol is not installed. This error may occur when the type of network protocol is changed during the product upgrade process.for information about adding a network protocol, see To add a network component. Link Error code The remote computer is not responding 721 A PPP conversation was attempted, but the remote computer did not respond. This error occurs when the server does not support PPP, such as a Windows NT 3.51 or earlier remote access server, or a SLIP server.this error may also occur if the server requires logging on by using a terminal window before starting PPP. See To use the Terminal feature to log on to a remote computer. If using a terminal window to log on solves the problem, you can automate the process for future connections. See Automating the dialup logon process by using Windows scripting.this error can also indicate faulty hardware on your computer, or the remote server. 722 Invalid data was received from the remote computer. This data was ignored 722 A PPP packet was received that is not in a valid format. Your system administrator may need to log PPP events to a file to solve the problem. For more information, see the Personal Support Center at the Microsoft Web site ( 723 The phone number, including prefix and suffix, is too long 723 The maximum length of the phone number, including prefix and suffix, is 128 characters. 726 The IPX protocol cannot be used for dial-out on more than one modem at a time 726 Only one connection can be used to dial out by using the IPX protocol. 728 The system cannot find an IP adapter 728 There is a problem with the TCP/IP configuration. Restart your computer to ensure that all recent configuration changes have taken effect. 729 SLIP cannot be used unless the IP protocol is installed 729 Verify that TCP/IP is installed. For more information, see To add a network component. Link Error code The protocol is not configured 731 Specific information was requested on a PPP control protocol that is not configured. To identify the PPP negotiation problem, ask your system administrator to enable PPP logging by using the Netsh.exe utility. 732 Your computer and the remote computer could not agree on PPP control protocols 732 PPP parameter negotiation did not succeed because the local and remote computers did not agree on a common set of parameters. See your system administrator to verify the configuration of network protocols such as TCP/IP, IPX, or NetBEUI. Also, your system administrator can enable PPP logging by using the Netsh.exe utility, which may help identify the PPP negotiation problem. 733 Your computer and the remote computer could not agree on PPP control protocols 733 The server supports PPP but does not support the network protocol for your connection. Ask your system administrator to configure the connection to use a network protocol that is supported by your server. Also, your system administrator can enable PPP logging by using the Netsh.exe utility, which may help to identify the PPP negotiation problem.

14 Page 14 of The PPP link control protocol was terminated 734 A PPP link control protocol conversation started, but terminated at the request of the remote computer. An error probably occurred on the server. See your system administrator. Also, your system administrator can enable PPP logging by using the Netsh.exe utility, which may help to identify the PPP negotiation problem. 735 The requested address was rejected by the server 735 Your connection is configured to request a specific IP address. Either the server is not configured to permit clients that request specific IP addresses, or the specific IP address may already be in use by another client. If possible, use DHCP to avoid addressing conflicts. See To configure TCP/IP settings. 736 The remote computer terminated the control protocol 736 A PPP network control protocol conversation started, but terminated at the request of the remote computer. An error probably occurred on the server. See your system administrator. Also, your system administrator can enable PPP logging by using the Netsh.exe utility, which may help to identify the PPP negotiation problem. 737 Loopback detected 737 The local and remote computers that are involved in the PPP conversation are the same computer. This usually means that a device (for example, a modem) on the link is echoing characters back. Try resetting these devices.for other vendor's servers, it may indicate that the remote computer is attempting a teletypewriter (TTY) login before connecting. You can configure the connection for a post-connect terminal on the Security tab. 738 The server did not assign an address 738 The server cannot assign an IP address to your computer from the pool of allocated addresses. Ask your system administrator to configure the connection to use a specific IP address on the client that does not cause a conflict on the remote network. Or, if possible, use DHCP to avoid addressing conflicts. See To configure TCP/IP settings. 739 The authentication protocol required by the remote server cannot use the stored password. Redial, entering the password explicitly 739 This error occurs only when making a PPP connection to a non-microsoft server. The standard PPP authentication protocols, used for interoperating with other servers, require that the password is available in plaintext form, but Windows stores only the encrypted form for security. 740 An invalid dialing rule was detected 740 The TAPI devices configured for Network and Dial-up Connections failed to initialize or are not installed correctly. Restart your computer to make sure that all recent configuration changes have taken effect. If the error persists, consult the event log for detailed warnings or errors. 741 The local computer does not support the required data encryption type 741 The Require data encryption (disconnect if none) check box is selected on the Security tab, but your connection does not have encryption capability. Clear the check box to use unencrypted connections or see your system administrator.this error may also occur if your password is longer than 14 characters, you selected the Require data encryption (disconnect if none) check box on the Security tab, and you selected Require secured password in Validate my identity as follows. Use a password less than 14 characters, clear the Require data encryption (disconnect if none) check box, and click Allow unsecured password in Validate my identity as follows.see To configure a connection. 742 The remote computer does not support the required data encryption type 742 The required level of encryption is not available on the remote computer. One computer is probably using 128-bit encryption technology while the other is using 40-bit or 56-bit encryption. See your system administrator to determine your level of encryption, and to verify that the server is using the same level of encryption.128-bit encryption is available without restriction for North American users of Windows 2000, Windows NT 4.0 with Service Pack 3, and Windows 9 x clients that use dial-up networking 1.2 and higher. You need to order separately the version of each of these products that supports 128-bit encryption. Availability outside of North America is determined by United States Government regulation. For more information, see Data encryption. 743 The remote server requires data encryption
