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. OssianModerator January 10, 2018 at 10:51 am #191909 If it is one of several DCs, why not blow it away, do a metadata cleanup and a fresh install. Far easier than troubleshooting it. If it is also hosting other roles (apart from DNS) please think carefully about security…. Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
