Hi,I'm uninstalling the Client Access Role on my Windows 2008 Server. I had some troube wtih the installation and it never really ran. So I'm trying to get rid of Exchange to make a fresh install.The log says something like this: Code Snippet [19.07.2008 12:59:36] [1] Processing component 'Client Access Services Configuration' (Configuring virtual directories and web services.).[19.07.2008 12:59:36] [1] Executing 'get-WebServicesVirtualDirectory -Server $RoleFqdnOrName -DomainController $RoleDomainController | remove-WebServicesVirtualDirectory -DomainController $RoleDomainController;', handleError = False[19.07.2008 12:59:36] [2] Launching sub-task '$error.Clear(); get-WebServicesVirtualDirectory -Server $RoleFqdnOrName -DomainController $RoleDomainController | remove-WebServicesVirtualDirectory -DomainController $RoleDomainController;'.[19.07.2008 12:59:36] [2] Beginning processing.[19.07.2008 12:59:36] [2] Beginning processing.[19.07.2008 12:59:36] [2] Administrator Active Directory session settings are: View Entire Forest: 'True', Configuration Domain Controller: 'WINDOWS2008.campus.local', Preferred Global Catalog: 'WINDOWS2008.campus.local', Preferred Domain Controllers: '{ WINDOWS2008.campus.local }'[19.07.2008 12:59:36] [2] Searching objects "WINDOWS2008.campus.local" of type "Server" under the root "$null".[19.07.2008 12:59:36] [2] Previous operation run on domain controller 'WINDOWS2008.campus.local'.[19.07.2008 12:59:36] [2] [ERROR] Exchange server "WINDOWS2008.campus.local" was not found.

The error indicates that exchange server "WINDOWS2008.campus.local" was not found. You should use command setup.com /mode:RecoverServer /roles:CA to reinstall CAS Server Role. By the way, since CAS Server high depends on IIS(Internet information Service), please ensure all required IIS features are installed before rebuilding the CAS role. You may use servermanagercmd to check all web server features installed. I suggest you uninstall and reinstall IIS 7 to ensure it works smoothly. -Jason
