Hi
I have a question regarding the SQL Server(SQL Server 7) port 1433.
Some body is trying to hack into our Windows 2000 server through port
1433. Is there a way i can close this port? I tried using a tool
called Ipsecpol.exe ( Internet Protocol Security Policies Tool). But
when we run netstat, it still looks like they are able to connect to
the server using port 1433. Has anyone come across this problem? I
would appreciate it very much...

Where do I find information on how to address and pass
data to and from the serial ports and USB ports in VB.
VB6 supports the serial ports easily but I see no
reference to using the USB ports.
VB.net literature does not provide any coverage on either
the serial ports or the USB ports.

Hi All,
I'm trying to connect to a virtual port (COM19, OUTGOING, "Bluetooth
Serial Port") using VS2005 System.IO.Ports.
When I ran the ff code below here's what happens.
1) VS2005 Compiles w/o errors
2) My Nokia 6600 prompted me the message "Accept Connection request
from DEMON?"
note: DEMON is my computers name.
3) Using my Nokia 6600, I hit the button that refers to the "Yes"

any ideas on how to block a network port from being used, or one that
is currently in use? For example, say I want to block port 23 from
being used. by used, I mean allowing connections to or from it.
thanks in advance.

Dear All,
I made an app in c# that uses several serial ports.
For the serial ports I use a pnp Sunix board, some with 8 serial ports
other with 4 or even 2 serial ports.
Whenever I use the development computer I don't have ay problem with
my application.

I'm trying to send some printer commands (ZPLII) to an attached USB printer
using the SerialPort component. I didn't get very far at all. In fact I
haven't gotten anywhere.
The first problem I encountered is that a call to SerialPort.GetPortNames()
returns an empty string. In other words, NO port names are returned. I'm
not terribly knowledgable about ports but from the Hardware Manager I did
notice that I don't have the Ports and...

I have a proprietary software on two different internal networks. on one the client-side software can access the server, and the second network, they can't.
I have no real clue which ports are needed,
1. What's the best way to find out? will telnet x.x.x.x port# work?
2. Does one side (server) have to be listening on a port to be able to detect that it is open? If it doesn't listen, than requests end up no where. right?
3. For...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
