Changing the numbers on COM Ports in Windows 2000

SchottSolar asked

I have a Windows 2000 machine with software that HAS to print to COM1.  There's no way to change that.  A user went in and deleted COM1 and it became COM3.  They have deleted the COM port several more time and the number keeps increasing.  I'm now up to COM11.  We're dead in the water without this printers

How do I change the number of the COM port back to COM1 in Windows 2000?

I assume you are referring to the printer ports being deleted. Can you open the printers window, click on File | Server properties | Ports and add them back in, using "Add a Port"?

If you are referring to the hardware port, you should be able to open the Add/Remove hardware wizard in the control panel and choose add/troubleshoot a device, then "add a new device", No, I want to select the hardware from a list, and choose ports.....


I'm talking about the hardware port, and I already tried what you suggested.  It also doesn't allow me to change the port number, it simply readds the port with the next sequential number.

Any other ideas?  Thanks for responding so quickly.

I haven't tried this but you could try editing the registry:
Default settings for Com Port 1 if you need them are:
IRQ = 4
I/O = 03F8
Baud = 9600
Data Bits = 8
Parity = none
Stop Bits = 1

If you are not familiar with editing the registry, please read the following regarding backing up, editing and restoring:
