Folder2iso great tool in Virtual Machine environment

Folder2iso is a tool that I use to convert my folders (and it’s subfolders) into ISO’s. This works great, espesially when working with Virtual Machines. Often it is the quickest way to have files available in the VM.

Error during PrepareSchema phase Exchange 2010 installation

Posted in Active Directory, Exchange 2010 with tags , on June 4, 2012 by uniekdevries

Before installing the first Exchange 2010 server in you organization you have to extend the Active Directory schema. This can be done by running the /PrepareSchema command from the Exchange 2010 DVD. In most cases this stage completes without errors. Except in our environment ;-(

The following error occured:

“There was an error while running ‘ldifde.exe’ to import the schema file ‘C:\Windows\Temp\ExchangeSetup\Setup\Data\PostExchange2003_schema18.ldf’. The error code is: 8245. More details can be found in the error file: ‘C:\Users\username\AppData\Local\Temp\2\ldif.err'”.

Looking into the logfile shows this:

Entry DN: CN=ms-Exch-Mobile-Mailbox-Policy-Link, CN=Schema, CN=Configuration,DC=domain,DC=local

Add error on entry starting on line 358: Unwilling To Perform The server side error is: 0x2114 Schema update failed: An attribute with the same link identifier already exists.

The extended server error is: 00002114: SvcErr: DSID-032603BC, problem 5003 (WILL_NOT_PERFORM), data 8468

Research learns that this error happens  occasionally.

To fix the problem I followed the instructions explained in this Microsoft knowledge base article

To edit the .ldf files I copied the whole content of the Exchange 2010 DVD to the local disk and started from there. At first the PrepareSchema action failed again. I found out that for some reason the setup did not copied the file that I edited but used the default file. To solve this I started the PrepareSchema command and manually copied the file that I edited in the temporary directory that was created by the PrepareSchema command.

In total there were two attributes with a link identifier that already existed. Both attributes were related to the Exchange Mobile Mailbox object.
