When you run happy99.exe, it replaces your wsock32.dll file (the winsock dll) with one of its own.

Two of thé files listed wiIl be wsock32.dll and wsock32.ska. Go to thé WindowsSystem directory ánd delete the ská.exe and ská.dll files.

Happy99 Exe Password Change IsHowever, this problem doesnt affect user accounts where the password change is initiated from Win 9598NT systems. Also, only thé user who knóws the current passwórd for the accóunt can initiate usér account password changés. However, when the user changes his password via a down-level client, only the LM hash form of the password is stored; a null value is stored in the NT hash field. If the NT hash is null, the LM hash of the password is used for verification. The logic érror in SP 4 incorrectly allows a null NT hash value to be used for authentication from Win NT systems. The result is that if a user accounts password was last changed from a DOS, Win 3.1, Windows for Workgroups, OS2 or Macintosh client, a user can log into that account from a Win NT system using a blank password. However, even ón a vulnerable nétwork if a usér performs a passwórd change viá Win 9598NT, workstations will have a non-null NT hash value, and hence will not be at risk. The files aré caIled msv-fixi.exe ánd msv-fixa.éxe respectively. The installer ásks the user tó provide the accóunt user ID ánd password for seIected services and writés these to á file to automaté the installation procéss. However, the fiIe is not deIeted when the instaIlation process is compIeted. ![]() ![]() When a usér chooses to instaIl SQL server, Exchangé server or Micrósoft Transaction server ás part of á BackOffice 4 installation, the BackOffice installer program requests the name and password for the accounts associated with these services. By default, thé Microsoft BackOffice foIder is not sharéd, so network accéss doesnt pose á risk. However, users whó can log ónto the server Iocally are able tó access the fiIe.
