Comment: Hello everybody.
I administrate small computer network - 30 computers.Mostly Win98 and 2 WinXP.
I have a server - PDC Windows NT 4 sp 6a.
The problems are: Very slow login, very slow file access on server. At users station sharing is allright but on server the access time is awfull.
On server i have DHCP,Wins servers.
Ping is okey at any time, name resolving is allright..

Reply: (edit)Dear
The first thing you see that all the servers are not on the same machine. Your FIle server and DHCP may be on one machine , rest take them onto another machine and cofigure the clients to access those servers accordingly.
If possible, check for viruses and cure them, will perform better.
ALso see that the anti-virus programs are not memory resident , may slow down the network.

Reply: (edit)Glad to hear you are defragging. That is usually the death of a server is not done. Your hardware looks OK. You don't mention having a BDC. A BDC assumes some of the authenication load thereby speeding up logons and resource access. The other area to look at is your topology. I assume you have a 10/100 switch and your server is connected to it at 100mb? What other switches/hubs do you have connected?

Reply: (edit)Forget. The Switchs are: 2 3com office connectors 16 and 24 ports.
They were tested while installing more than fine.
Network cards ONLY 3com.
Network - all clients and servers 100mb full duplex mode.

Reply: (edit)"the HASP service die " What do you mean? I never heard of any hasp service. Everything is pointing to a problem with the server. Look at event viewer for clues to hardware or software problems. Reinstall service pack 6a. It is amazing how many things get fixed by reappling a service pack. Look at the port stats on the switch for the server nic card. Be on the lookout for crc or frame errors. That can indicate autonegociation issues or cabling problems. How much memory in the server and processor? Hard drive configuration?
