A custoumer have 4 winXp hosts and a win 2003 server connected through a Catalyst Express 500 switch. The hosts have a network share mapped on the server. After implementing the switch, hosts periodic loses connection to the mapped network drive.
There is no alerts on the switch, and no events in the alert log. I have downloaded Cisco Network assistant, and connected it to the switch. When connected with this, I get lots of system messages ! Some of them are severity 3-errors with interfaces changing state. All hosts ports are configured with "Desktop" role. The server port has "Server-Business" role. There is also a non-cisco router connected to the same VLAN. The port role for this port is "Router"
What can the cause be ?
