Hi,
The LAN in my company is as the following.
-10-user workgroup
-server & all clients running Win98
-LAN connect to the broadband ISP via a Linksys router/gateway.
-no proxy installed.
-5 pc are linked by a hub, another 5 pc are linked by another hub
While our internet connection is perfectly ok, there seems to be some odd problems in our LAN since about 1 week ago.
The 1st situation is like this:
1 of the client pc(client 9 on LAN) had been taken out of the office for presentation. When it's brought back, i found the NIC got loose from the pci slot, so i inserted it back properly into the pci slot, & reinstalled the NIC driver(D-Link DFE-538TX Fast Ethernet Adapter). By double-check with my own working pc, i've made sure all settings for the following are correct:
-local IP for that client pc
-DNS IP
-workgroup name & that client pc's name
-gateway ip
-subnet mask
-file & print sharing
Besides, i've made sure the correct driver has been installed for the NIC. For the logon options, i've tried 'Microsoft Family Logon' & 'Windows Logon'.
For this client pc, no password is assigned, & what the user does is just hit Enter.
B4 this client pc was brought out of office, it had been working fine, can see server & all clients on the workgroup.
But now, despite trying many times of uninstalling & reinstalling the NIC driver, this client pc seems could not properly get connected to the LAN.
When it's log on to the LAN for the first few minutes, it couldn't see all PCs on the LAN(in Network Neighbourhood) instantly, unlike in the past. It takes about 10 to 15 minutes for this client pc to be able see other PCs on network. But even if so, it can only see the clients pc connected with the same hub, which are 5 clients. The other 5 PCs including the server could never appear in Network Neighbourhood.
When checked the UTP cable that links this client pc to the 8-port hub, i found only certain empty ports could provide connection( by looking at the led). But even having tried each available port, the situation for this client still the same: can see other pc but cannot access.
There was once when i plugged the UTP cable to 1 of the port, i notice the Collision led blink periodically. What does this mean ? What's the use of the Collision led on the hub ?
Then when i tried other empty port, the collision led no more blinking.
-------------------------------------------
From this client :
ping to other clients that it can see -- each result is 'Request Time Out'
tracert to other clients -- each time no response
-------------------------------------------
The 2nd situation is like this:
Client 8 on LAN suffers the reverse from the above: it can ping,tracert,net view, net use to server & other clients on the LAN with the results all show up instantly( but couldn't do so from itself to client 9 & client 7),
but couldn't see all pc on network most of the time.
In the past, when client 8 got into Windows, it could see all pc on the LAN in just a click on Network Neighbourhood. But now, it takes very long time to wait for all pc turn up in
Network Neighbourhood, sometimes even couldn't see at all.
Besides, other clients also have the similar situation -- wait for ages to see the entire network.
Would anyone pls shed some light on why is this happening & how should i deal with it?
Could occasional power blackout have long-term 'accumalative' effect on the cable & network adapter in the pc ?
Any ideas appreciated. Many thx.
