1. Here is the GUI that I used in the Server CORE demo last night - http://blogs.microsoft.co.il/files/folders/guyt/entry68860.aspx

2. Unattend.txt for building Server CORE RODC -

[DCInstall]
AutoConfigDNS=Yes
ConfirmGC=Yes
CriticalReplicationOnly=No
DisableCancelForDnsInstall=No
Password=
RebootOnCompletion=No
ReplicaDomainDNSName=Corp.com
ReplicaOrNewDomain=ReadOnlyReplica
replicationSourceDC=SWIG-DC-01.corp.com
SafeModeAdminPassword=
SiteName=BranchOffice
UserDomain=Corp
UserName=administrator

3. I used Virtual PC 2007 for my environment. In order to deploy the VMAdditions to the Server Core Image, you need to do the following:

At the command prompt:

• Press Right Alt I to mount VMadditions
• Browse to D: (Mounted image) 
• cd windows
• setup.exe

Thats it....VMadditions will now run!
