Hello, I'm trying to run domainprep in a child domain, the exchange 2003 server is in the parent. Domainprep is failing giving the error - "Setup failedwhile installing sub-component domain-level permissions with error code 0xC0070560" The exchange enterprise servers and exchange domain servers groups are both in the Uses OU. Thank you.

Hi Do you have the necessary permissions?Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

Yes, I think something went wrong though. I deleted teh exchange enterpise servers and exchange domain servers groups in the child domain and ran domain prep again, no problems. Is that likely to cause me problems later on though?

Yes AFAIK, please continue with the steps Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog
