DOCUMENT:Q191192 28-JUL-2001 [win95x] TITLE :Cannot Change Password with DUN 1.2b and 128-Bit Encryption PRODUCT :Microsoft Windows 95.x Retail Product PROD/VER:Win2000:95 OPER/SYS: KEYWORDS:kberrmsg dun win95 kbDialUp ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft Windows 95 ------------------------------------------------------------------------------- SYMPTOMS ======== If a new account logs on using the Point-to-Point Tunneling protocol (PPTP) and the Change Password On First Logon option is enabled, the user is prompted to change the password. During the password change, however, error message -629 is generated and the PPTP connection is dropped. The following entry appears in the system log on the PPTP server: Error 741: The local computer does not support the required encryption type. Note that this behavior occurs only if 128-bit encryption is being used. CAUSE ===== This behavior occurs because the Dial-Up Networking (DUN) 1.2b client does not use the correct hashing to encrypt the password. STATUS ====== Microsoft has confirmed this to be a problem in the Microsoft Dial-Up Networking 1.2b client. To resolve this issue, upgrade to DUN 1.3.
