Domain conrtoller issue

Dear Experts

Thank you so much for this amazing website and we are appreciated  your helpful support .

First of all i try to migrate my domain controller from 2003 to 2008 , so i made the steps that mentioned in the attach file
also i did the necessary steps for migrate my environment from 2003 to 2008
but the problem was when i stop the main domain the additional domain (the expected domain) was not working after i shutdown the main domain (the becoming additional domain)
nevertheless there was replication between the two domains

after all i made , i return all the thing to the begging , and stay to see free time to solve my problem in the right time (i am going to asked it later in new case)

i mentioned that when i try to enter to any domain service such as active directory users and computers or active directory site and services i receive a message as it is mentioned in the attach file  

so please , could you help me in solving my problem

Thanks and Regards

one of the error targets to schema issue ...Scary thing

Lets start with dcdiag /q/v and repadmin /replsum
Please post output of above two commands and any event logs in Directory service logs in both DC's
BTW did the innitial replication completed successfuly
See this thread it will solve your issue
If I were you I would start checking as below:

First run DCDiag /v on both the DCs, I'm sure you'll see connectivity test failed. Check DNS Settings, use this link DNS Best Practices then run repadmin /replsum if you see any errors then work on them. After that last but not the least check Time Server settings, as you've made 2008 as PDC make this server as authoritative time server and other machines shall point to PDC for Time sync, check this link Authoritative Time Server. I'm sure after you fix these settings MMCs will work.

As suggested post the dcdiag /q and repadmin output of both DC.Also ensure correct dns setting on DC too:http://abhijitw.wordpress.com/2012/03/03/best-practices-for-dns-client-settings-on-domain-controller/
