Hi Andrew,

I played around a bit.

in source4/selftest/tests.py line 696

for env in ["rodc", "promoted_dc", "ad_dc", "fl2000dc", "fl2008r2dc"]:

which sets the targets for the test. If I remove the fl2000dc target, the 
fl2008r2dc works just fine.

If I change the line to:

for env in ["rodc", "promoted_dc", "fl2000dc", "ad_dc"]:

sefltest fails to provision the ad_dc target.

So the fl2000dc taints the environment!


I need to investigate further but the questions which comes to my mind is: Why 
do we still support fl2000?

Cheers,
