Hello Andrew & list,

This has not been a Samab4 issue but strange configuration side effect.

Issue has been resolved by editing CN=NTDS
Settings,CN=<SERVERNAME>,CN=Servers,CN=Default-First-Site-Name,CN=Sites,<COFIGURATION> "option" attribute from 0x7 to be 0x1.

Strange side effect:
I have started with dcpromo of "Windows Server 2008R2 64bit" at
functional level 2000-native (both forest & domain). Then I made a
snapshot. After which I opened "Sites-and-Services" tool and from there
I started to raise the forest functional level then take snapshots.
Unfortunately after 1 or 2 of these cycles the above attribute gets
changed to 0x7 which rejects all inbound and outbound replication. As a
result of that my 2008 and 2008R2 snapshot levels did not work.
