Hello,

We have an OES SP1 Server and Windows XP SP2 Client with Novell Client 4.91
SP1. We have an application (Lotus Notes Client) that hold its Data on the
users private drive H:\. The clients are randomly losing the connection to
the network and the Lotus Notes Clients hang with the error "network path
not found". We have then to kill Lotus with the task manager and restart it.
We have captured packets with ethereal and we see always a similar
behaviour:
in this example Server-IP 192.168.224.1, Client-IP 192.168.224.123

After 3 minutes !!! the client send an RST packet to the server
