hi
i find the registry key for disable DP, But we are to do log out so that WLM disable DP
[HKEY_CURRENT_USER\Software\Microsoft\MSNMessenger\PerPassportSettings\xxxxxxxxx\]
"PerPassportAppSettings"=dword:00005001 (DP disable)
"PerPassportAppSettings"=dword:00004001 (DP enable)
"UTL"=hex:xx,xx,xx etc.... (directory of DP)
Regrettably it does not solve my problem to deactivate my DP without disconnecting.
