When you start the DHCP Server service manually from Control Panel, you receive the following error message:

Can't start the Microsoft DHCP Server Service on \\<machine-name>.
Error 2140: An Internal Windows NT Error Occurred.

When you start the DHCP Server service from a command line, the following error message will be produced:

System error 10049 has occurred.
The system cannot find message for message number 0x2741.
The message file for BASE.

CAUSE

This problem can be caused if the server's IP address or addresses listed in the registry contain leading zeros in one or more octets. For example: 015.057.120.001.

When the DHCP Server service starts, it fails to come up on any of these computer.

Adding leading zeros to the IP address from TCP/IP GUI Setup will not write to registry. However, it is possible to enter leading zeros in IP addresses in an Unattend.txt file; these leading zeros can be written to registry.

RESOLUTION

Do not use leading zeros for any of the IP addresses listed in an Unattend.txt file.

STATUS

Microsoft has confirmed this to be a problem in Windows NT Server version 4.0.
