HI all,

this is wrecking my head as cant find a fix. When i go to try to connect to the internet up appears the message that "Port is already open"

I have went into msconfig and made sure no progs were starting at startup. I restart and still i get this message.

If i go into control panel > modem > diagnostics and click more info i get the same message.

IU have read that killing the rnapp.exe prog will resolve the problem but it doesnt.

Has anyone any ideas???
 
I've had this happen with bad cards, and when trying to use an old card with Windows XP. Make sure you have ALL modem drivers removed before installing new modem.
 
Check to see if the old modem is still installed. If so remove it. Make sure the modem u are using is the defult modem.
 
How about taking it to the next step and removing the port?
Also anything relating to it in networking.

It should reload the port on the next reboot.

Reinstalled dialup networking and didnt seem to work.

Rebooted into safe mode and removed modem from device manager, rebooted and let windows install modem. It seems to work.
It was only starting using selective start up with only "Process system.ini file" and "Process win.ini file" selected.

I restarted and going to Control Panel > Mdodems > Diagnostics > More Info and was getting "Port already open"

Shut down.
Started and still the same thing and no sign of Rnapp.exe in task manager.

Reset the winsock and tcp/ip stack using WinsockFix.exe - rebooted to no avail.

Installed the latest version of DUN - rebooted - "Port already open"

All this time no sign of Rnapp.exe in Task Manager.

I have also went through the steps outlined below:

Put your Windows 98 CD in the tray and hold the SHIFT
key to stop it running.
Start Menu > Programs > MS-DOS Prompt.
Type the following command exactly as shown below,
but substitute the X: with your CD Rom Drive Letter:

EXTRACT /A X:\win98\BASE4.CAB rnaapp.exe /L
c:\windows\system

Say NO when prompted to overwrite the file, but take
note of the CAB file that it would be extracted
from. You should see something like this:

Cabinet WIN98_46.CAB

Overwrite c:\windows\system\rnaapp.exe (Yes/No/All)?

Press "N" and close the DOS Window. Now execute the
command line:

EXTRACT /A X:\win98\BASE4.CAB tapisrv.exe /L
c:\windows\system

and note the cab file containing the file. It will
probably be in the same CAB file as rnaapp.exe ie.
WIN98_46.CAB.

Copy that .CAB file from the "win98" folder of your
CD into some new neutral folder on your hard drive
eg. C:\RNAPCAB.

Create the following lines in Notepad and save to
your "C:\Windows\Command" folder as "RNAP.TXT".
Right-Click and rename as "RNAP.BAT" and accept the
warning about changing file types.

@echo off
extract /Y "c:\rnapcab\WIN98_46.CAB"
rnaapp.exe /L c:\windows\system
extract /Y "c:\rnapcab\WIN98_46.CAB"
tapisrv.exe /L c:\windows\system
exit

Now restart the computer, but jab the F8 key
repeatedly as the system boots until you see the Boot
Menu.
Arrow down to "Command Prompt" and press <Enter>
When it stops at the C:\> Prompt, type the command
RNAP and press <Enter>.

This will overwrite these files with fresh ones from
the CD, and will do so while they are not loaded in
memory.

Power off, then restart the computer.

TO NO AVAIL

Again, removed modem from Device Manager and
everything from Network in Control Panel -shutdown
and moved the new modem to another pci slot.

Started and through reboot installed the modem -
reboot.

Control Panel > Mdodems > Diagnostics > More Info and still getting "Port already open".

I AM OFFICIALLY LOST!
 
IRQ for the device match the PCI slot you installed it in? Address appear OK?
Don't have a 98 with a modem so no capability of dualing your setup.

How about locking it out of Plug and Pray by withholding the IRQs in the CMOS and forcing it to a PCI IRQ, then killing the HKLM Enum key and forcing it to rebuild the hardware in the registry?
Will probably require the M/B cdrom since 98 may not have current drivers.

would you be able to give me more info on that - step by step nearly?
 
On bootup, go into setup. May have a page called PNP/PCI configuration which allows you to disable PNP. Also can assign IRQs to PNP or legacy ISA.
Chipset configuration may allow serial ports to be configured manually: COM1 3F8 and IRQ4, COm2 at 2F8 and 3:

Boot up and run regedit, expand HKLM, hilight ENUM, click edit key, click delete. This deletes hardware references. Reboot and the OS will reload hardware references ir can find. You may need to add hardware references to any M/B hardware that OS can't find. Normally by loading the M/B CD or by refreshing any questionable drivers in the hardware mangler.

I would try setting the PCI IRQs manually to keep them out of the clutches of the OS. Will keep the OS from using a normal serial port IRQ for a PCI IrQ. Plug & pray is an "Alice in Wonderland" function. When it is good, it is very, very good. But when bad...., that is how it got the mosnomer, well deserved.

Thanks edfair but in order to resolve the problem i carried out a complete format and reinstall and now the system is working fine although had problems finding drivers for the mobo - chipset.

Anyways i will never let AOL near one of my systems and told the person whos machine it was not to either - i have a niggling feeling this was the root of the problems.

Cheers everyone
