Just some feedback regarding my experiences with Win 2008:
For the LCPM course VM I created the domain and users in LC directly (no LDAP) and this went down fairly well, but did require a small workaround in the exercise of lesson 7. I haven't yet had time to build a proper LDAP-enabled VM.
For the LCDO course VM I ran into some other issues related to PDF Generator. In particular it related to the UAC feature in new Windows versions, but I also noted an issue with the PDFG Readiness testing tool. After resolving both issues I documented my experiences in the hope of preventing other people from spending a saturday afternoon at the office.

Enough work for now, the game between England and South Africa is starting in 10 minutes...
