DHCP server log files may be corrupted in Asian language versions of Windows Server 2008, such as in the Japanese edition, in the Chinese edition, or in the Korean edition. In these DHCP server log files, there is no CRLF code, and the last few bytes of each line are truncated. Therefore, different lines may be merged into one very long line.
This problem does not occur in the English editions of Windows Server 2008.
DHCP server log files are saved in the %windir%\System32\Dhcp directory.
This problem occurs because, when the DHCP server service outputs logging, it assumes that the characters are in half-length Unicode format. This assumption is true for English language characters. However, this does not apply to Asian language characters, such as to Chinese, Japanese, or Korean characters.
