Hi,I am trying to install Sharepoint Server in a Windows Server 2008 x64 OS. At first it was successfully installed and configured. After working for some days due to some wrong administrative job the SharePoint server stopped working. I tried to fix the issue but could not do it.So I uninstalled it, removed databases from Database server and again tried to install it. This time it installes properly but at the time of configuration at step 5 it fails. The error messagereads: "Failed to register SharePoint services" and in detail section it reads: "An exception of type System.Security.Cryptography,CryptographicException was thrown.Following below is the truncated log file:Begin trace logging for SharePoint Products and Technologies Configuration Wizard.

Hi, This is a common issue when uninstall and reinstall SharePoint on the same machine, some files in the MachineKeys folder give access denied error even though you had local administrative privileges. please set the MachineKeys folder had the correct default Permissions referred to KB278381 (http://support.microsoft.com/kb/278381). -lambertSincerely, Lambert Qin Posting is provided "AS IS" with no warranties, and confers no rights.
