Windows Dienste fehlerhaft?

[bvk]

In einem gemischten Netz habe ich 12 Win XP Clients mit einer Cad Software laufen.Konstant haben wir lästige, nicht katastrophale, Probleme weil anscheinend die Serververbindungen unterbrochen werden, worauf das Cad Programm einfriert. In ServerAdmin gibt es eine Latte von Fehlermeldungen. Ich denke da gibt es Konfigurationsfehler. AFP läuft für die restlichen 30 Clients einwandfrei.
System 10.4.8 Server auf MacPro Intel, Open Directory Master
Ich erwarte keine Problemlösung, vielleicht aber einen Hinweis wo anzusetzen wäre. Die Fehlermeldung kommt zum Schluss, enthalten ist ein An- Abmeldevorgang, ein Serverneustart mit erneutem Anmeldevorgang eines Win Clients.
Danke BvK
