I am having a problem trying to access new 2008R2 DC from  2003SP2 DC to transfer roles. When I try to attach to the 2008 server from AD schema in the console, I am getting a Login attempt failed. The domain controller could not be set.

 I can attach from the 2008 DC to the 2003 Server though. I did all the basic checks; DNS is in synch, time is correct on both servers. Everything looks good when running DCdiag and repadmin commands. Any help would be greatly appreciated.

Have you run the ADPREP utility from your 2008 DVD yet? You have to run that so that your 2003 AD will have the upgraded Schema for the 2008 DC.
run addprep /forestprep
then
run adprep /domainprep

If you have already extended the schema (which is something you should have done beforehand) then you need to do the FSMO roles transfer from the DC you want them to be transferred.
So from the Windows 2008 R2 DC you will access the following tools in order to transfer the roles:
1) Active Directory Users and Computers to transfer RID, PDC, Infrastructure Masters, right click on the domain name and select "Operations masters"
2) Active Directory Forests and Trusts to transfer "Domain Naming Master", right click on top of the node of the tree and select "Operations master"
3) Active Directory Schema to transfer the "Schema Master", right click on the node of the tree named "Active Directory Schema [fqdn of your current DC] and select "Operations master", more info about it here: http://technet.microsoft.com/en-us/library/cc759254%28v=ws.10%29.aspx
