DHCP Server Cannot Be Accessed with Dhcpadmin.exe Tool

ID: Q189038

The information in this article applies to:

Microsoft Windows NT Workstation version 4.0 SP4
Microsoft Windows NT Server version 4.0 SP4

SUMMARY

SYMPTOMS

On a computer running Windows NT 4.0 with Service Pack 4, when you start the DHCP Manager from a DHCP server running Windows NT 4.0 with Service Pack 3 (for example, \\server\c$\WINNT\system32\Dhcpadmn.exe) and then double-click the DHCP Server, DHCP Manager fails with the following error:

Unable to connect to DHCP server at X.X.X.X.
Server may be down, or DHCP service not started.

CAUSE

When you run the Dhcpadmin.exe utility from the %SystemRoot%\System32 folder on a server running an earlier Service Pack version, the program will use the supporting *.dll files from this network directory instead of the local %SystemRoot%\System32 folder, which causes incompatibilities on the system.

RESOLUTION

For DHCP manager to function properly on the workstation:

Install the DCHPadmn.exe utility on the workstation from the Windows NT 4.0 Server compact disc, Clients\srvtools\winnt\setup.bat.

Reapply Service Pack 4 to the system to update these files.

NOTE: Rename the $ntservicepackuninstall$ folder so that it will not be overwritten when reinstalling Service pack 4.
