Daily Logon problems... (LAN about 700 nodes)

by fatalzio / August 21, 2006 11:44 PM PDT

Hi... I'm having troubles with some computers in the LAN of my job, this LAN is about 700 nodes, everyday some users want to login, they receive the next message: No domain server was available to validate your password. We use the winipcfg to renew the network adapter, sometimes works sometimes not.

Obviusly the PC's have their cable connected and there's no problems with the jack or the configuration of the connector.

PC's with this problems are Win98 SE and this happens everyday with several users.

Do you think this is a computer problem or a DHCP server problem?

Any idea??

I ran into this years ago.

Not only was the OS Windows 98se but they had those DUMB HUBS in the network. Slowly we recovered by not only getting a better IT staff that knew about drivers and more but tossing out DUMB HUBS for SWITCHED HUBS. The prior IT staff had to be let go since they keep at it by reloading 98se improperly and had deveoloped a bad attitude. Even the looming layoff didn't help them get their act together.

After replacing the dumb hubs, a few network cards and a dozen installs (more?) did the network settle down.

Hope this helps.

Well, we have just passed trough a LAN Refresh (Servers, Switches Cisco) and we have start the migration to XP, but this will take some time.
There's only 1 XP laptop wich presents the same problem ocassionally...

If the XP is not of an IT load.

Then I would turn to the servers to see if they are up to the task. While we had some 50 users (way back) on a single pentium 100 MHz "server" it was NT 4.0 Server and did quite well for its day. Today I still see such issues in the wiring plant.

The IT staff is key to all this. It's best you prod them as need be to get them to dive in, find and fix the issues.

You may expect there is some magic fix to all this but in the decades I've been at this (pre-CP/M days) to today it's the good IT staff you need to find and cure these items.

Apparently not.

If this happens on XP clients also, as stated above, it clearly is a network or server issue, as Bob said. Surely not a client problem.

The IT staff should solve it.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
