Ping mit Fehlermeldung 10040: Message too long

[Assertor]

Zitat von devidespe:

IF TReplyStatusTypes <> rsEcho THEN PingError:=True;

Das sollte besser:
if IdIcmpClient1.ReplyStatus heißen.

Ansonsten mal das Timeout hochsetzen?
IdIcmpClient1.ReceiveTimeout := 5000; Mal zur Erklärung übrigens:

Zitat:

For Windows NT and Windows 2000, administrator privileges are required to allow TIdICMPClient.Ping to work properly. The command line PING application does not exhibit this behavior because Microsoft chose to use undocumented calls in ICMP.DLL and its winsock implementation to get around the issue. In short: they cheated. Indy does not use ICMP.DLL to maintain Linux compatibility, and allow use of both Raw sockets and ICMP sockets.
