"Please reconfigure a different IP address" error message and the OK button becomes unavailable when you use the Change IP Address Tool in Windows Small Business Server 2003 (885684)


The information in this article applies to:

  • Microsoft Windows Small Business Server 2003, Premium Edition
  • Microsoft Windows Small Business Server 2003, Standard Edition

SYMPTOMS

When you use the Change IP Address Tool to change the IP address that is assigned to the Server Local Area Connection network connection in Microsoft Windows Small Business Server 2003, you experience all the following symptoms:
  • You receive the following error message:
    The static IP address that was just configured is already in use on the network. Please reconfigure a different IP address.
  • When you click OK, you receive the following error message in the Change IP Address Tool dialog box:
    An error occurred while changing the IP address. Your server might be partially configured. We recommend that you run the Change IP Address Tool again and enter the original IP address of the server.

    If this error message appears again, ensure that the local network adapter is enabled in Network Connections and that it is connected to a switch or hub that has power. Also, open Services, and ensure that any services having a startup type of Automatic are running.

    If the error message still occurs, see the log file at C:\Program Files\Microsoft Windows Small Business Server\Support\Changeiplog.txt.
    When you click OK, the Change IP Address Tool quits unexpectedly.
  • When you next try to change this IP address assignment by using the Change IP Address Tool, you cannot do so. In this scenario, the OK button in the Change IP Address Tool dialog box is unavailable and appears dimmed.

CAUSE

This issue occurs if a duplicate IP address exists on the local network or if an invalid IP address is assigned to the network connection. This issue occurs if one of the following conditions is true:
  • You use the Change IP Address Tool to assign an IP address that is already being used on the network to the Server Local Area Connection network connection. In this scenario, the IP address of the Windows Small Business Server is set to 0.0.0.0.
  • You assign an IP address that is already being used on the network to the Server Local Area Connection network connection. To do this, you modify the IP address in the Internet Protocol (TCP/IP) Properties dialog box of the network connection, and then you run the Change IP Address Tool.
  • An invalid IP address and an invalid subnet mask are assigned to the Server Local Area Connection network connection, and then you run the Change IP Address Tool.

RESOLUTION

To resolve this issue, assign a new IP address to the Server Local Area Connection network connection, and then run the Change IP Address Tool.

Note By default, in Windows Small Business Server 2003, the local area network (LAN) connection is named "Server Local Area Connection." If the LAN connection on your computer is not named Server Local Area Connection, modify these steps accordingly. Additionally, you can view the Changeiplog.txt file to determine the computer's original IP address, subnet mask, and default gateway. This file is located in the following folder:

%PROGRAMFILES%\Microsoft Windows Small Business Server\Support

Note If you have never run the Change IP Address Tool, this file will not exist.

To modify the IP address for the LAN connection, use one of the following methods.

Method 1: Use the graphical user interface

  1. Click Start, point to Control Panel, point to Network Connections, right-click Server Local Area Connection, and then click Properties.
  2. Click Internet Protocol (TCP/IP), and then click Properties.

    Note Do not clear the Internet Protocol (TCP/IP) check box.
  3. Click Use the following IP address, and then type a valid IP address in the IP address box.

    Note This IP address must be unique on your network. Additionally, this IP address must be an address that is in the range of IP addresses that you use on your network. For example, type 192.168.0.2.
  4. In the Subnet mask box, type the subnet mask that you use for your network. For example, type 255.255.255.0.
  5. In the Default gateway box, type the IP address of the computer or of the device that connects your network to another network or to the Internet. For example, type 192.168.0.1.

    Note Typically, if your Windows Small Business Server-based computer has more than one network adaptor installed, you do not have to specify a default gateway for the Server Local Area Connection network connection. In this scenario, leave the Default gateway box blank.
  6. In the Preferred DNS server box, type the IP address of the computer that resolves host names to IP addresses. If your Windows Small Business Server-based computer is configured as your DNS server, type the same IP address that you typed in the IP address box. For example, type 192.168.0.2.
  7. Click OK, and then click Close.
  8. Run the Change IP Address Tool to change the IP address of the Windows Small Business Server-based computer and to update all the Windows Small Business Server-based components with the new IP address information. To run this tool, follow these steps:
    1. Start the Server Management tool.
    2. Expand Standard Management, and then click Internet and E-mail.
    3. In the right pane, click Change Server IP Address.

Method 2: Use the Netsh command

  1. Click Start, click Run, type cmd, and then click OK.
  2. Type the following command, and then press ENTER:

    netsh interface ip set address "Server Local Area Connection" static 192.168.0.2 255.255.255.0

    This command sets the IP address of the network connection that is named "Server Local Area Connection" to 192.168.0.2. Additionally, this command sets the subnet mask to 255.255.255.0. If you want to use a different IP address or subnet mask, or if your network connection is not named Server Local Area Connection, modify this command accordingly.
  3. Run the Change IP Address Tool to change the IP address of the Windows Small Business Server-based computer and to update all the Windows Small Business Server-based components with the new IP address information. To run this tool, follow these steps:
    1. Start the Server Management tool.
    2. Expand Standard Management, and then click Internet and E-mail.
    3. In the right pane, click Change Server IP Address.
  4. If your Windows Small Business Server-based computer has only one network adaptor enabled, you may have to specify a default gateway on the Server Local Area Connection network connection. In this scenario, you may not be able to connect to the Internet if you do not specify a default gateway.
