3 quick questions, on a brand new OES2SP2 dsfw install I cannot do the following things, is this correct/how do I correct?

1) Cannot write to netlogin share or sysvol share as Administrator through Windows
2) DNS does not create an entry for a newly registered windows server or pc
3) In Group Policy the Administrative Templates section is blank in the Default Domain Group Policy and if I create a new Group Policy in an OU I get the error in the attached image file.

Many Thanks
