Windows 2000 network issues

This size is configurable by modifying the SocketPoolSize registry entry in the following subkey in the registry:. Ephemeral port allocation and the MaxUserPort registry entry Ports that are allocated as part of the socket pool are pulled from the set of available ephemeral ports on the server.

On Windows-based servers, the MaxUserPort registry entry defines the ephemeral port range and defines the highest port number that can be is allocated for ephemeral ports. The MaxUserPort registry entry is in the following subkey in the registry:. Effective ephemeral port range when the value of the MaxUserPort registry entry is set explicitly In Windows Server or in Windows Server, the value of the MaxUserPort registry entry defines the ephemeral port range.

The range is from to the value that is defined by the MaxUserPort registry entry. After you install security update on Windows Server and down-level platforms, the following conditions are true:. If the value of the MaxUserPort registry entry is set, the ports are allocated randomly from the [, MaxUserPort] range.

If the value of the MaxUserPort registry entry is not set, the ports are allocated randomly from the [, ] range. Effective ephemeral port range Ephemeral port allocation occurs in the [] port range before you install security update on Windows Server This port allocation behavior does not change after you install security update To view the current ephemeral port range, run the following command:.

Network Monitor -- Captures and displays all packets on the network. These icons are organized similarly to those in the Printers folder, with each icon representing a unique connection, as well as an icon that you can double-click to add a new connection. In this case, each icon represents a network or dial-up networking session. Simply double-click the icon called Make New Connection to create new network or dial-up networking connections. Windows then launches a wizard that guides you through the process.

You can use the individual connection icons to review or modify connection properties. Laptops and disappearing networking icons Laptop computers behave a bit differently. On a laptop system, the Network And Dial Up Connections window would still contain the Make New Connection icon, but it would probably also contain one or two icons related to dial-up networking.

One icon might be used to connect to an Internet service provider, while the second icon might allow a dial-up connection to a corporate RAS server. Laptops also have icons for LAN connections in this folder, but their behavior is strange. When the computer is connected to one of these devices, the icon for it exists.

However, when you remove a PCMCIA card or disconnect from a docking station that contains a network card, the connection icon disappears until the network device is reconnected. This wireless networking requires a special network card. Can you get a ping response from the local host?

Just a double check - Windows required reboots for a lot of things that XP and higher don't. After installing the NIC did you reboot? I can't remember if each of those needs a reboot or not, it's been a while since I've touched , but it sure couldn't hurt.

Go into the managed switch or the NIC on the machine and change the value of "auto-negotiate" on one or the other. You want to set it to depending on the switch and card or Full duplex or Half Duplex. I had experienced this many times in the past.

Thanks for all the suggestions. I can get back on the machine Friday, when it is not being used for production. This gives me tons of ideas to try. Need to try and ping the localhost, there is not keyboard, just a machine control so that will require copying the ping command to a floppy and copy pasting.

DHCP is working everywhere else on the network. I did try and change the negotiation, but only from auto to full. I will try other options. Well, I just got a few minutes on the machine. I can ping local host, the IP I statically assigned, but nothing else.

Changed the negotiation rates. It has auto, full, , 10 full, and None led to any change. I also tried all these settings with another switch in the closet. Is it currently set to a static?

Certain the switchport is good?
