Error Code 8224 Ldifde Exchange 2010 installation failure

Question

Hi, here is a problem I have been bashing my head with for about a week. I am transitioning to Exchange 2010 from 2003. I have two DC's running Windows Server 2003 Sp2, one of which is the Exchange 2003 server. I have just brought online a windows 2008R2
member server, which I am attempting to install exchange 2010 on. I get the following error message during installation.
Organization Preparation
Failed
Error:
The following error was generated when "$error.Clear(); install-ExchangeSchema -LdapFileName ($roleInstallPath + "Setup\Data\"+$RoleSchemaPrefix + "schema1.ldf")" was run: "There was an error while running 'ldifde.exe' to
import the schema file 'C:\Windows\Temp\ExchangeSetup\Setup\Data\PostExchange2003_schema1.ldf'. The error code is: 8224. More details can be found in the error file: 'C:\Users\administrator.CFN\AppData\Local\Temp\2\ldif.err'".
There was an error while running 'ldifde.exe' to import the schema file 'C:\Windows\Temp\ExchangeSetup\Setup\Data\PostExchange2003_schema1.ldf'. The error code is: 8224. More details can be found in the error file: 'C:\Users\administrator.CFN\AppData\Local\Temp\2\ldif.err'
Elapsed Time: 00:00:22
And from the ldif.err:
The connection cannot be established
The error code is 8224
Now I have checked dns, all is good. I can resolve the DC without issue.
I have done dcdiag and netdiag and passes all tests. I have even written a hosts file, all this to no avail.
Any help would be appreciated.
Thanks

I had a same and I fixed this........
Solution
1. The error is happening at the "Organization Preparation" stage, so let's go 'old school' and do that manually.
2. Locate the server on your network that is the schema master (Locate FSMO Servers).
3. Put the Exchange 2010 DVD in the schema master (Or share it over the network and connect to it from the schema master server).
4. Drop to command line and change to the DVD Drive/Directory with the Exchange 2010 setup files in it.
5. ONLY do this if you have Exchange 2003 already! Run the following command, (If no Exchange 2003 present, skip to the next step).
X:\Setup /PrepareLegacyExchangePermissions (Where "X" is CD ROM derive letter)
6. Run the following command:
X:\Setup /PrepareSchema
7.
Run the following command:
X:\Setup /PrepareAD
Note: At this point it may fail, and say it requires an organization name, (it will do this if it finds no existing container in Active Directory).
Error
Exchange organization name is required for this mode.  To specify an organization name, use the /organizationName parameter.
If that is the case, then run the following command:
X:\Setup /PrepareAD /OrganizationName:"Your required org name"
Reboot your server and try to install exchange 2010.
