IMPORTANT: This article contains information about modifying the registry. Before you modify the registry, make sure to back it up and make sure that you understand how to restore the registry if a problem occurs.

256986 Description of the Microsoft Windows Registry



SYMPTOMS
On multihomed computers that have only one network adapter connected to the network, the following Dynamic Host Configuration Protocol (DHCP) message may appear every time you start the computer:

The DHCP Client could not obtain an address. If you want to see these messages in the future choose yes, otherwise choose no.



CAUSE
The DHCP service on the client computer tries to obtain and renew a lease; the DHCP message is the expected behavior if this does not succeed. Typically, this is better handled by configuring the computer to have different hardware profiles and booting into the right profile.



RESOLUTION
A supported fix is now available from Microsoft, but it is only intended to correct the problem that is described in this article. Apply it only to computers that are experiencing this specific problem. This fix may receive additional testing. Therefore, if you are not severely affected by this problem, Microsoft recommends that you wait for the next Windows NT 4.0 service pack that contains this fix.

To resolve this problem immediately, contact Microsoft Product Support Services to obtain the fix. For a complete list of Microsoft Product Support Services phone numbers and information about support costs, visit the following Microsoft Web site:

http://support.microsoft.com/default.aspx?scid=fh;EN-US;CNTACTMS

NOTE: In special cases, charges that are ordinarily incurred for support calls may be canceled if a Microsoft Support Professional determines that a specific update will resolve your problem. The typical support costs will apply to additional support questions and issues that do not qualify for the specific update in question.

The English version of this fix should have the following file attributes or later:   Date        Time    Size    File name     Platform --  07/24/2000  03:29p  38,672  Dhcpcsvc.dll  Intel 07/24/2000 03:28p  64,784  Dhcpcsvc.dll  Alpha

This fix introduces a new registry entry that you can use to prevent the DHCP message from being displayed even once.



STATUS
Microsoft has confirmed that this is a problem in Windows NT 4.0.



MORE INFORMATION
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.

If you install the hotfix by using the hotfix installer, the installer adds the new registry entry.

If you apply the fix manually, you must add the registry value:  Start Registry Editor (Regedt32.exe). Locate and click the following key in the registry:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Dhcp\Parameters

 On the Edit menu, click Add Value, and then add the following registry value:

Value Name: PopupFlag

Data Type: REG_DWORD

Radix: Hexadecimal

Value: 0

 Quit Registry Editor.</li></ol>

NOTE: To restore the original behavior, set the PopupFlag value to a data value of 1. If the PopupFlag registry value does not exist, the default is 1, and the message is displayed.
