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.
