I a small network running WINNT4.0 Server with Win98 Workstations. I have one Workstation that has a very slow connection to the server as well as all the shared resorces on the Network. all the Workstations have the same 2 protocals installed, TCP/IP and NetBEUI. This machine is very slow on bothe the TCP/IP ( downloading files from the Web) and accessing files from the local network. I have changed the NIC and checked the wiring. what could be slowing this machine down?

1) Have you checked the hub? (the hardware)
2) The Hub settings
3) The IP settings in the computer; sometimes a strange setting may cause the problem.
4) How about the topology of your network?
5) What are the differences between this computer and other similar computers? (Hardware? Software settings? or special place/positions of the topology?)

I have Eliminated the possibility of the Network Hardware as the possible source of the problem by swapping workstations. The problem follows the slow PC no matter where on the Hub it is connected.

You may try installing the most updated drivers for the NIC, reinstalling the NIC to a new slot, making sure that you don't have any other protocols installed that are not necessary. Of course, this could be a problem that expands beyond the network. It could be another hardware issue aside from the NIC or cabling. Have you tried disconnecting it from the network to see if it takes an extraordinarily long time to open similar non-networked files or applications?

I Tried this Today and Applications from within the Machine run as expected from a 1GIG Processor with 256MB RAM.

If the hardware problems are eliminated; then the software problems are assumed.

1)The Winsock of the computer: So deleting it and re-installing it; but the process is a headache; please refer to winsock problems answered in this forum.

2)The IE may have a problem; So a full-re-installation may help.

3)The Windows system has conflicting versions of the similar drivers. (use the file system checker.)But sometimes, it does not cure and a full re-installation can help.

If all the options are tried and there are similar computers (which works well) with the same hardware as this one. The easy option: format the computer and ghost the whole win98 workstation to this one. Or all the installations problems may eat up lots of time.

It was Probably a faulty winsoc! i removed TCP/IP and dialup networking and reinstalled the components. It is up and working normaly.

I have had this problem myself.

My first solution was to remove NetBEUI (and install IPX/SPX) which removed one of the slow systems.

The second solution was to re-install the modem which cleared the problem of the second slow system.

The third item to watch is that you aren't waiting for DNS/WINS response on the NIC when the service isn't available.

Finally (the 'DOHH!' option) check that you aren't clashing on an IP address - I managed this with a new network switch once!

Virus scan. Also there is a free porg called ad-aware that checks for bandwidth using spyware and the like. Also make sure the nic is in full duplex mode, network properties of the nic. There is also the packet size or mtu settings but I doubt that,and forget how to get to the adjustment.
Hope this helps

i work on networks and have noticed that most times when machines are slow there is nothing wrong with the hardware on the network or the machine. The issue arises with the use of MS. First thing first check the system resources. Even though allmachines use the same hardware and apps some will run at different system resources. If it is getting a bit low just run the msconfig app and clear up the start-up tab.
