Hi nichaly,
Open the registry editor and navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\Cu rrentVersion\Winlogon
Check for the existence of a Notify_Disabled subkey under Winlogon. If
that
subkey exists, delete it.
Now, navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\Cu rrentVersion\Winlogon\NotÂ*Â*ify
Check for the existence of a SensLogn subkey. If SensLogn does not
exist,
you will need to add this missing key and its values. Copy/paste the
following, between but not including the two sets of asterisks, into
Notepad
and then Save as a file named SensLogn.reg
NOTE: the [HKEY_LOCAL_MACHINE\SOFTWARE\......\Notify\SensLogn] line in
this
post will wrap to two lines...it needs to be on one line in Notepad.
Also,
ensure that you have the blank line at the end.
********************
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows
NT\CurrentVersion\Winlogon\Notify\SensLogn]
"DLLName"="WlNotify.dll"
"Lock"="SensLockEvent"
"Logon"="SensLogonEvent"
"Logoff"="SensLogoffEvent"
"Safe"=dword:00000001
"MaxWait"=dword:00000258

"Reconnect"="SensReconnectEvent"
"Unlock"="SensUnlockEvent"
"Impersonate"=dword:00000001
"Asynchronous"=dword:00000001
********************
Once you have created and saved the SensLogn.reg file, double-click on
it,
then click on Yes when asked if you want to merge the information into
the
registry. Restart your computer for the changes to take effect.
