I'm using packer and answerfile to build windows server image. When I set autologon and AdministratorPassword as plaintext, it works fine.
However, when I set autologon and AdministratorPassword as plaintext=false, I get an error shown below.
<AutoLogon>
<Password>
<Value>cAB3AEEAZABtAGkAbgBpAHMAdAByAGEAdABvAHIAUABhAHMAcwB3AG8AcgBkAA==</Value>
<PlainText>false</PlainText>
</Password>
<LogonCount>1</LogonCount>
<Username>Administrator</Username>
<Enabled>true</Enabled>
</AutoLogon>
<UserAccounts>
<AdministratorPassword>
<Value>cAB3AEEAZABtAGkAbgBpAHMAdAByAGEAdABvAHIAUABhAHMAcwB3AG8AcgBkAA==</Value>
<PlainText>false</PlainText>
</AdministratorPassword>
</UserAccounts>
Error
Windows could not parse or process unattended answer file for pass [oobeSystem]. Setting specified in the answer file cannot be applied. Error was detected while processing settings for component Microsoft Windows shell setup.
I noticed that when I just use autologon with plaintext=false and delete adminpassword alltogether, it works.
What seems to be the issue here?
