Windows 2000 Professional Fatal Logon Error

[neopets_35]

Greetings,

Just very recently, I've received a logon error message which states the following: -

The system cannot log you on now because the domain (computer name) is not available.

I received the logon error message in my Microsoft Windows 2000 Professional computer which was installed alongside with Service Pack 4 and Update Rollup 1. As the computer is used by only a user, thus I am the administrator of the computer. By the way, there is no password for the machine as well.

Unfortunately, I receive the error message above every time I'm trying to log into my Windows 2000 computer. I've attempted to log into the machine through normal booting and safe mode several times, but it seems that all my attempts failed me miserably. I've also tried all the available troubleshooting options, but they failed as well. I could not even gain access into my machine at all! I was puzzled with the fact that my domain is unavailable as I did not alter any of my system configurations the last time I logged into my system.

Please assist me in solving this fatal error, please! Your help is greatly appreciated.

Try the "Last Known Good Configuration" boot option...

As I have stated in my initial post before, I have tried the option, "Last Known Good Configuration" already. Unfortunately, it did not work. In fact, I tried all the troubleshooting options (except the debugging mode), but they did not work at all.

So, what now?

I faced a similar problem when i messed around with my friends company machine. I changed the workgroup name, because of which the machine went off the company's created domain and the user was deactivated. But either way i was able to log in through the administrator. I really don't know if its a similar kind of error.

It's a corrupted Winsock layer. Follow the instructions below.

How to repair network or modem connectivity issues in Windows 2000.

Sometimes, no matter how many times you uninstall TCP/IP or Network drivers, your computer refuses to connect properly to the network. Signs usually entail erratic network connectivity, webpages won't load when first accessed, no ip address is bound to the adapter, etc. The instructions below provide a way to essentially REINSTALL TCP/IP and fix corrupted Winsock registry values. If these steps do not work, the best thing to try is to run a repair using your Windows 2000 CD.

Remove TCP/IP

Note Before you remove TCP/IP, make a note of the IP and the DNS settings.

Click Start, point to Settings, and then click Network and Dial-up Connections.

Right-click Local Area Connection, and then click Properties.

In the Components checked are used by this connection list, click Internet Protocol (TCP/IP).

Click Uninstall, and then in the Uninstall Internet Protocol (TCP/IP) dialog box, click Yes.

When you are prompted to restart your computer, click Yes.

Delete the Bind registry value, the Tcpip subkey, the Winsock subkey, and the WinSock2 subkey

Click Start, click Run, type regedit in the Open box, and then click OK.

In the left pane, expand HKEY_LOCAL_MACHINE, and then expand SYSTEM.

Expand CurrentControlSet, and then expand Services.

Expand lanmanserver, and then click Linkage.

In the right pane, right-click Bind, and then click Delete.

In the Confirm Value Delete dialog box, click Yes.

Expand lanmanworkstation, and then click Linkage.

In the right pane, right-click Bind, and then click Delete.

In the Confirm Value Delete dialog box, click Yes.

Right-click Tcpip, click Delete, and then in the Confirm Key Delete dialog box, click Yes.

Right-click Winsock, click Delete, and then in the Confirm Key Delete dialog box, click Yes.

Right-click WinSock2, click Delete, and then in the Confirm Key Delete dialog box, click Yes.

Restart your computer.

Reinstall TCP/IP

Click Start, point to Settings, and then click Network and Dial-up Connections.

Right-click Local Area Connection, and then click Properties.

Click Install, click Protocol in the Click the type of network component you want to install list, and then click Add.

In the Network Protocol list, click Internet Protocol (TCP/IP), and then click OK.

Replace the IP and the DNS settings with the values that you made note of at the beginning of the "Remove TCP/IP section."
