When you use the Microsoft Remote Installation Services (RIS), by default, the Administrator password is set to null (blank) during the installation. You can, however, let the user set a password during the final GUI portion of installation. To do so, perform the following steps:

1. On the RIS server, open the .sif file of the installation you want to modify. By default, this file is in the RemoteInstall\Setup\\[language\]\Images\\[folder name\]\I386\Templates folder with a name of Ristndrd.sif.
2. Go to the \[GuiUnattended\] section of the .sif file, and find the line that says: AdminPassword = *.
3. Change this line to: AdminPassword = "".
4. Save the change.

During installation, the system will prompt the user to type an Administrator password. Test the change to ensure that it works correctly.

As a side note, instead of "" you could type a password (e.g., AdminPassword = "fred"), which sets the Administrator password to the password you specify and doesn't prompt the user. However, this password travels as clear text, so I don't recommend this approach. The Windows 2000 Resource Kit describes another option (although not well). You can use a Custom Installation Wizard (CIW), and let the user type in a password, but this approach is quite complex.
