Locked

unreliable network connection

By agaskill ·
I have 3 Win98SE workstations connected to a Win2k server for file sharing, and they often lose their connection to the server. If they reboot they can connect again. The server reports no error.

What's more, these workstations often "freeze" for a second or two where nothing happens and the cursor won't move. Occasionally they'll lock up entirely.

Wondering if it was a network problem, I ran a continuous ping from the server to each workstation. The first day I was losing about 5% ofmy pings to one computer and the others were fine. The next day I was losing about 5% to a different computer and the other two were fine. Today I've been losing pings to two of the computers, but less than 1%.

Every 10 pings or so, the problemclient's response time, which is normally <10ms, jumps to 500ms or more. It doesn't correspond to delayed pings on the other client.

Checking the simple stuff, does the server have sufficient memory, or is it swapping? Is there other traffic on the network which might be swamping the network.

The performance monitor on the server should tell you these things.

Good luck.

I was having a similar problem on two separate file servers, and asked the same question last month. I just posted a probable solution, but I will repeat it here.

1) The WIN2K Server CD includes a file, DSCLIENT.EXE (in the \CLIENTS\WIN9X directory), that needs to be installed on every client machine that uses any OS lower than WIN2K. It allows the client to use KERBEROS authentication. 2) AUTODISCONNECT on the Server needs to be shut off. Do this from the Command Line... Net Config Server /autodisconnect:-1

I am not certain if these solutions actually solve the problem. But after a week I have only been disconnected once, versus 1-2 times a day prior to that.

Microsoft online tech support DOES NOT tell you about #1, and admits #2 is not documented

If you are using 3COM NIC's Microsoft reports that they will sometimes randomly drop connections.
