On this page of the Windows® Internet Explorer® Customization Wizard 8, if you are an Internet service provider, you can configure your users' dial-up connections so that they can connect to your Internet server.


The Internet sign-up option is not available for the Windows Vista® operating system.

Item Details

Connection name

Type the name of your sign-up server. This can be a friendly name.

File name

Type the file name for your file. The file for sign-up parameters should have an .isp extension. The file for Internet settings should have an .ins extension.

Area code/Phone number

Type the area code and telephone number for this connection.


You can prevent a default area code from being set by setting a flag in the .isp file. The syntax for this flag is: Dial_As_Is=Yes.

Country code/ID

Type the country/region code and the country/region ID for this connection.


Type the default user name for this connection.


Type the default password for this connection.

Support phone number

Type the telephone number that users can dial for support.

URL of first online sign-up page

Type the URL of the first page in the sign-up process.

Advanced Options

To set the following dialing and gateway settings, click Advanced Options.

  • Use static DNS address

  • The Domain Name System (DNS) is a set of protocols and services for Transmission Control Protocol/Internet Protocol (TCP/IP) networks. DNS enables you to use friendly names, such as www.microsoft.com, instead of numeric addresses. To ensure that all DNS servers are searched in an attempt to map name and IP addresses, select this check box and type a primary address and an alternate address.

  • Requires Logon

  • Select this check box if you need to ensure that the client computer has Windows logon authentication turned on. Providing a Windows password enables access to the Windows password cache, where the Internet service provider (ISP) password is stored. This option is particularly useful if you assign long random strings as passwords. This option is valid only for client computers running Windows 95 and Windows 98.

  • Negotiate TCP/IP

  • Select this check box to enable TCP/IP negotiation when the user is establishing an Internet connection.

  • Disable LCP

  • Select this check box to disable the use of Link Control Protocol (LCP) extensions in establishing a point-to-point protocol link. If the sign-up server cannot handle LCP extensions, you should disable LCP on the client computer that is connecting to your server. This value is valid only for client computers running Windows NT® 4.0.

  • Dial number as shown

  • Select this check box to prevent a default area code from being set. You might want to set this flag if, for example, users might call from an area code different from the default. If users are not aware that the default area code differs from their current area code, they could unexpectedly incur long-distance charges.


    You can prevent the setting of a default area code by setting a flag in the .isp file. The syntax for this flag is: Dial_As_Is=Yes.

  • Encrypt passwords

  • Select this check box to specify that only encrypted passwords can be sent to or accepted by your computer. This is useful if you need additional security for this connection. The computer that you are connecting to must support encrypted passwords.

  • Use software compression

  • Select this check box to specify that incoming and outgoing information is compressed before it is sent, which speeds up the transfer of information. Compression occurs only if both computers are using compatible compression methods.

  • Use IP header compression

  • Select this check box to use TCP/IP header compression, which is designed to improve the efficiency of bandwidth use over low-speed serial links. It typically optimizes data transfer between computers. When a smaller header that identifies the connection and indicates the fields that have changed is constructed, fewer bytes have to be transmitted. For compression to work, however, packets must arrive in order.

    Compression may not always be desirable. For example, if you are using older equipment, you might not be able to use compression. For the sake of interoperability, Serial Line Internet Protocol (SLIP) drivers that allow header compression should include some sort of user-configurable flag to disable compression.

  • Use default remote gateway

  • Select this check box to specify that IP traffic is routed to the wide area network (WAN) connection by default. A gateway is a connection or interchange point that connects two networks that otherwise would be incompatible.
