The "netsh" command changes the Byte option value when you export and then import a DHCP server configuration file in Windows Server 2003 SP1 (923492)

SYMPTOMS

Consider the following scenario. On a Microsoft Windows Server 2003 Service Pack 1 (SP1)-based server, you use the netsh dump command to export a Dynamic Host Configuration Protocol (DHCP) server configuration to a file. You then use the netsh exec command to import this same configuration file to a different DHCP server.

In this scenario, the configuration file that you import may lead to wrong values in the Byte option values. Additionally, there is no error message when you import the configuration.

MORE INFORMATION

When you run the netsh dhcp server 10.0.0.1 dump command to create a script file for your current DHCP configuration, you will find output that resembles the following if you use the Byte option values in DHCP:

DHCP Server 10.0.0.1 Scope 192.168.0.0 set optionvalue 222 BYTE 101

Note The 101 value represents the decimal interpretation of the 222 option that was defined as a Byte value.

When you use the netsh Dhcp Server 10.0.0.1 Scope 192.168.0.0 set optionvalue 222 BYTE 101 command to create a new Byte option value or to change an existing one, the 101 value is then interpreted as a hexadecimal value instead of a decimal value. Therefore, the 222 option is set to 0x01, a decimal value of 1, instead of 0x65, a decimal value of 101.
