Very Slow Uplink Port Express 500

[mrichter]

We have a Cisco Express 500 with two 1GBit Uplink ports.

These 2 Ports are connected to Win2k3 Servers.

The Clients are connected to the 100 MBit Ports of the switch.

Now the problem is that we have a very bad speed from the Servers to the Clients.

The speed from the Clients to the Server is OK.

The speed between the two 1 GBit ports (Servers) is in both directions OK.

The speed between clients is in both directions OK, too.

Before researching on this issue, I would like to know the following.

1. Are the connections to all the clients from the server is slow?. Or else, only to particular clients?. Are all the clients having the same OS?. Also let me know the following.

1. The GBIC/NIC card used in the switch, server and client.

2. The OS used in your clients.

3. How many clients you have in your network connecting to that particular server?.
