All, Prior to deploying Exchange 2010 we are trying to get TDP for Exchange to work in our test environment. Exchange 2010 RU3 SP2 and TDP version 6.3. We can successfully snap to tape but when we try to restore a mailbox (original location, alternate location, or pst) the operation fails with these errors:
An Active Directory error 0x51 occurred when trying to check the suitability of server 'domain-controller'. Error: 'Active directory response: The LDAP server is unavailable.' ACN0151E Errors occurred while processing the request. During the operation I can see an established LDAP connection to the domain controller in question. Google hasn't solved it for us yet - thanks in advance for any advice. Peter
