RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may
require you to reinstall your operating system. Microsoft cannot guarantee that you can solve
problems that result from using Registry Editor incorrectly. Use Registry Editor at your own
risk.
To resolve this issue and configure the "Allow calling computer to specify its own IP address" feature, use the appropriate method:
Method 1
NOTE: The registry key listed below will only be used if the remote access policy is set to "Server settings define policy." If the policy is set to anything else, then the registry key is ignored. Once the registry key is set manually, configuring or disabling RRAS will not reset the registry key.
Use Registry Editor (Regedit.exe) to locate the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RemoteAccess\Parameters\Ip
Add a new DWORD Value with the following registry value:
Value Name: AllowClientIpAddresses
Data Type: REG_DWORD
Value: 1
Method 2
Windows 2000 RRAS and the Internet Authentication Service (IAS) use remote access policies to determine if a connection should be accepted. You may configure the "Allow calling computer to specify its own IP address" feature by modifying remote access policies. By default, Windows 2000 configures a default policy called "Allow access if dial-in permission." You can either modify the default policy or create a new policy. To modify the default policy:
NOTE: By following the steps below, any client with remote access rights will be allowed to request a Transport Control Protocol/Internet Protocol (TCP/IP) address. If you do not want every client to be able to do this, you must create a new policy with new conditions. Then, only users who meet the conditions of the policy will be allowed to request a predetermined TCP/IP address.
- Depending on how your user authentication is configured, open either the IAS Microsoft Management Console (MMC), or the RRAS MMC snapin.
- Select Remote Access Policies.
- Right-click Allow access if dial-in permission is enabled, and then click Properties.
- On the Policy Condition dialog box, click Edit Profile.
- From the Edit Dial-in properties dialog box, click IP.
- Click Client may request an IP address, click OK, and then click OK.
