I get Logon.exe – Bad Image C:Windowssystem32SspiCll.dll is either not designed to run on windows or it contains an error………… I am able to login if I boot in safe mode but still yet to work out how to fix this problem. I ran sfc /scannow and no issues. I tried to copy SspiCli.exe from a working machine but wont let me do that either as it tells me its in use. Any help would be appreciated.
