During the installation of OCS 2007, I get a fatal error during the web components setup. The entry in the “LC Web Components” log that appears to indicate the error is:

"Error 29024. Error 0x80004005 (Unspecified error) occurred while executing command 'C:\WINDOWS\system32\CScript.exe'. For more details, check log file 'C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\LCSSetup_Commands.log'.

Within "LCSSetup_Commands.log" if found this:

The "ASPNETSetup_00019.log" contains the following error...

"2007-08-24 10:00:08 Starting Creating list of client site scripts dirs

2007-08-24 10:00:08 Failure Creating list of client site scripts dirs: CreateSiteClientScriptDir failed with HRESULT 80070003: 'The system cannot find the path specified. "

The server is Windows Server 2003, Exchange 2003, SQL Server 2000, and is acting as a domain controller.

I'm guessing the problem is related to the "\\.\.BackOfficeStorage\" path, which (again i'm guessing) is possibly some exchange configuration gone wrong in IIS?

Can anyone help?

many thanks!
