The default location of the file SymRasMan.dll is %SystemRoot%\System32\rastls.dll. On installing Symantec Antivirus or Symantec Endpoint Protection the default location is then changed and edited in the registry to C:\Program Files\ Symantec\Symantec Endpoint Protection \SymRasMan.dll. After uninstallation this location is not reversed. The issue occurs because of a problem with registry keys which are not reverted to the defaults or .dll files indicated in registry values do not exist after removing Symantec Endpoint Protection 11.0

These 2 registry hives are affected

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP\EAP\25 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\RasMan\PPP\EAP\13

·         ConfigUiPath

·         IdentityPath

·         InteractiveUIPath
