Today I was at one cutomers and they had two Windows 2003 domain controllers. They bought another server and wanted to install domain controller on Windows 2008 R2.

When I installed role Active Directory Domain Services I wanted to run adprep to modify AD forest and AD itself. When I ran adprep /forest my screen stucked on new line for a while. I thought adprep is working, but it was not. I waited at it for an 10 minutes. Nothing changed:

Stucked ADPrep

Also adprep log file was empty. 🙂

Appeartely adprep was not going to do his job. After couple Process Monitor lookings I found out that adprep is looking for directory “en-US”  in its own directory. But there was no “en-US” directory at my installation DVD:

Missing directory en-US

I know that M$ started to create multilanguage packages and in those directories are stored just language versions. Then I just created directory en-us and copied content from cs-cz into en-us adprep started to do its work:

working adprep

There is couple weird things:

• Why do I have just cs-cz directory on my DVD even I use only english distros of DVDs?
• Why did adprep say it’s missing directory?
• Why adprep log was empty?
• Why do I have English adprep even the directory was called cs-cz (Czech Republic)?
• Why did adprepr didn’t fall into only one directory available?

I don’t think M$ will ever answer this question and neither they will fix it. 🙂 But thing is that when I was missing en-us directory, I could press “C” and Enter and adprep would do its job done and I would never know what has been done.
