The LMCompatibility property is designed to work directly with the "HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\LSA\LMCompatibilityLevel"
|
||
|
|
and will act as this key is documented. This effects how NTLM authentication
|
||
|
|
is done on the server. We do not pull the value from the registry because other systems
|
||
|
|
don't have a registry and you may want to set this to a value that's different from
|
||
|
|
your registry.
