Good Morning,
I have been working to get my first 2008 R2 seerver promoted to a domain controller so I can start taking down my 2003 dc's. I have the server up and running all patched and all my forest prep preresiquists complete. I am seeing a few things that concern me and would like to know if the group can tell me if I am safe to go ahead and do the upgrade.
I do have a few SMB client running on my network. A copier that send scannned pdf's to network shared folders. And A NAS server that I do backups to.
So give that information when I run dcpromo on the new 2008 server i get the following warninings.
Warning #1 I believe this is ok i have no nt4 servers,
Windows Server 2008 and "Windows Server 2008 R2" domain controllers have a new more secure default for the security setting named "Allow cryptography algorithms compatible with Windows NT 4.0." This setting prevents Microsoft Windows and non-Microsoft SMB "clients" from using weaker NT 4.0 style cryptography algorithms when establishing security channel sessions against Windows Server 2008 or "Windows Server 2008 R2" domain controllers. As a result of this new default, operations or applications that require a security channel serviced by Windows Server 2008 or "Windows Server 2008 R2" domain controllers might fail.
Platforms impacted by this change include Windows NT 4.0, as well as non-Microsoft SMB "clients" and network-attached storage (NAS) devices that do not support stronger cryptography algorithms. Some operations on clients running versions of Windows earlier than Windows Vista with Service Pack 1 are also impacted, including domain join operations performed by the Active Directory Migration Tool or Windows Deployment Services.
For more information about this setting, see Knowledge Base article 942564 (http://go.microsoft.com/fwlink/?LinkId=104751).
Error #2 I dont think this is an issue but would love some feedback If I should have a Read-only DC

Error #3 This is where I have stopped because I am not sure of the impact of this.
