C# TCP-Socket-Fehler 10060

Ich habe einen windows-Dienst als server fungieren. Und ich führe eine windows-form-Anwendung der form localhost als client. Beide Programme verwenden die TCP-socket-Verbindung zum senden/empfangen von Daten.
Server lauscht auf port 8030. Das Programm funktioniert einwandfrei.

Aber wenn ich den enhanced client-Programm, um die Kommunikation auf bestimmten port sagen wir mal 9030. Während die erste Verbindung zum server generiert es die folgende Ausnahme.

Ein Verbindungsversuch ist fehlgeschlagen, da die Gegenstelle nicht ordnungsgemäß reagiert nach einer gewissen Zeit, oder die hergestellte Verbindung war fehlerhaft, da der verbundene host nicht reagiert 192.168.10.198:8030

Jeder Vorschlag wird sehr geschätzt werden.

Dank,
Madhusmita
