My attempt to upgrade Exchange 2010 on SBS 2011 failed with the following error when it got to the client access role:
Exchange Server component Client Access Role failed.
Error: Error:
The following error was generated when "$error.Clear();
Install-ExchangeCertificate -services "IIS, POP, IMAP" -DomainController $RoleDomainController
" was run: "An IIS directory entry couldn't be created. The error message is Cannot create a file when that file already exists.
. HResult = -2147024713".
An IIS directory entry couldn't be created. The error message is Cannot create a file when that file already exists.

Directory Path: IIS://localhost/W3SVC/1

Cannot create a file when that file already exists.
Now IIS is completely unworkable. Any ideas?
