Unattended Setup May Not Work During Upgrade from Windows NT 4.0 To Windows 2000 (257814)

The information in this article applies to:

Microsoft Windows 2000 Server
Microsoft Windows 2000 Professional

This article was previously published under Q257814

SYMPTOMS

You may receive the following error message when you automate the upgrade of a Windows NT 4.0-based computer to Windows 2000:

The specified Setup script file (path:\unattend.txt) is inaccessible or invalid. Contact your system administrator.

NOTE: This error message occurs when you use an Unattend.txt file from the command line (for example, winnt32 /unattend:unattend.txt).

CAUSE

This behavior occurs because the UnattendMode=FullUnattended parameter is missing in the Unattend.txt file.

For example, if you are performing an upgrade and you want to automate the application of the Product ID, the following causes the error message:

[Unattended]
NTUpgrade=Yes

[UserData]
ProductID="xxxxx-xxxxx-xxxxx-xxxxx-xxxxx"

RESOLUTION

To resolve this behavior, add the UnattendMode=FullUnattended parameter as shown in the following example:

[Unattended]
NTUpgrade=Yes
UnattendMode=FullUnattended

[UserData]
ProductID="xxxxx-xxxxx-xxxxx-xxxxx-xxxxx"
