why cannot i create socket?

[IPOz]

Hi,friends
On my windows 2000 professional box,i can NOT visit internet using IE,mozilla,etc. The reason is all of those can NOT create socket !
I have used a program to test it and found that the socket() function always returned -1 .I donot know why it happens?
BTW, the socket() is in ws2_32.dll.

Any suggestion is appreciated ! IPO_z@cmmail.com

i have tested it using the following code snippet:
...
FSocket := socket(PF_INET, SOCK_STREAM, IPPROTO_IP);
if FSocket = INVALID_SOCKET then begin
errCode := WSAGetLastError();
case errCode of
WSANOTINITIALISED:
raise ESocketError.create('WSANOTINITIALISED');
WSAENETDOWN:
raise ESocketError.create('WSAENETDOWN');
WSAEAFNOSUPPORT:
raise ESocketError.create('WSAEAFNOSUPPORT');
WSAEINPROGRESS:
raise ESocketError.create('WSAEINPROGRESS');
WSAEMFILE:
raise ESocketError.create('WSAEMFILE');
WSAENOBUFS:
raise ESocketError.create('WSAENOBUFS');
WSAEPROTONOSUPPORT:
raise ESocketError.create('WSAEPROTONOSUPPORT');
WSAEPROTOTYPE:
raise ESocketError.create('WSAEPROTOTYPE');
WSAESOCKTNOSUPPORT:
raise ESocketError.create('WSAESOCKTNOSUPPORT');
else
raise ESocketError.Create(
Format('%s -> error code=%d',[sCannotCreateSocket,errCode]));
end;
end;
...
it will report 'cannot create new socket -> error code=10106'.But 10106 is undocumented
How did the error happen ?
Some day ago i installed mozilla-0.9.9 and it is great for me to browse internet.Yesterday i ever visited

10106 means my box can NOT find the PDC(Primary Domain Controller). But how can i resolve it ?

Now i suspect that my box has been hacked by some one as it still can NOT login in the domain when i use another computer.When i used the new box i loginned successfully at the first time however it didnot work from then on

i used the following command to find out which ports are open:
c:\>netstat -a | grep -i listen
there are many open ports which i am not familiar with.How do i know which processes are listening on those port ?

Does there exist any registry settings to disable the domain login ?

BTW,i can login the local box and visit network by TCP/IP.

If you suspect a hacker, and you have many ports open, try the following, testing your internet connection after each suggestion:

1] Use the MSCONFIG program to see what is running at startup, and un-check anything that is not absolutely needed. Then re-boot and check your internet. If it works, one of the un-checked programs is the culprit. Now use a process-of-elimination to figure out which one.

2] Un-install and then re-install the TCP/IP network protocol, the network adaptor, and "Client for Microsoft Networks". (as foound in the properties for your network connection)

3] Make sure you have an up-to-date anti-virus program, and have run a FULL virus scan on your computer.


If this is all very obvious to you, just ignore it. If not...

Have a look at "Active Ports" for monitoring connections and an easy to read output.

Thanks for all your answers ! i will test the Active Port as soon as possible.
