Error code: 0xc0070534 - This error appears to map to "No mapping between account names and security IDs was done" (
Error code 1332) error description. From a newsgroup post: Few conditions when this error can occur:
1. The error code can occur if the Admin Group was previously a mixed AG and the EX5.5 server was not properly decommissioned. If the EX5.5 was improperly decommisioned there may be references to security info that were needed to connect to the EX5.5 server during co-existence.
2. Exchange 5.5 Service account renamed.
3. Two Way trust not working between the NT4.0 EX5.5 Domain and the WIN2K AD
EX2000 domain.
From another post: "Explicit permissions are required to write to the Ex5.5 Org, Site and Config Containers from the WIN2K side. E2K needs to write certain things to the Dir of the Ex5.5 side. If it does not have permission, it will fail. The "0xC0070534" error is related to permissions.
As per
ME294159, this may occur if you renamed the Exchange 5.5 service account to something other than the default value of "Administrator." This causes Setup to send incorrect parameters to the Exchange 2000 portion of the integrated setup, which results in the inability to successfully upgrade the Exchange 2000 Server component.
Error 0x8007203a = "Server is not operational" - See the link to
Error code 8250. If this occurs during Exchange setup then you may find additional clues about the problem in the Exchange Server Setup Progress.Log file.
Error code: 0x8009000f = "Object already exists" - See the information for
