Ever since I installed WIN98 2nd ED I have failure to connect to my ISP Inever had a poroblem with Win 95. About every sixth time I try to connect I get this error message RNAPP caused invalid page fault in module <unknown> at 0000:7fff32f2 then I notice all my running application icons normally in the volume control and time box in the task bar disappear. When I hit CTRL/ALT/Delete they are still listed however. I have reformated my drive and reinstalled Windows 98 and it has not changed. Once the failure occurs I cannot connect to the Internet no matter if I use IE.5.0 or Outlook EX. I have to shut down and reboot.

Please advise.

RNAAPP is part of Dial Up Networking. Try removing and reinstalling DUN.

One other thing, are you installing some type of software on your system provided by your ISP? If so, when was the last time you got a new CD from them? If the CD is old I would get a new copy. There were changes made to DUN from W95 to W98. If you are using an old copy or a copy intended for W95 then the software may be having a problem when it creates your DUN connection.

I have removed the entire comunications program and reinstalled it. This was after I made a clean installation of Win98 2EX I also removed my dial up connection and reinstalled it, also Ditto with the modem. I do not use the servers CD I always made my own connection and I also used the connection Wizard and still get the error message about every six times I try to connect.

There is a DUN update for W98SE to 128bit at the Windows Update site. Though it does not seem to be related, you could try it.

Also, what all do you have running at Startup. It's possible another program, is causing the failure. Start>Run type in msconfig and press enter. Click on the Startup tab.

Or try running Drwatson. Start>Run, key in Drwatson and press enter. When the error occurs you will see DrWatson appear on the screen. See if it gives anymore clues to the cause of the error.

Thanks for the speedy response. I am trying all of the suggested fixes. Since it is an intermittent problem it may be a few days before I will be able to advise you if any cured the problem.

I have now tried all of the suggestions and the problem remains. I strongly suspect a possible Memory Chip leak. What is your opinion on it being the possible cause. Looking back on past history I did find I had a Internet error problem about two years earlier when I was running Win 95 and I replaced the Memory chip and the problem was gone.

My suspicions proved to be correct. I replaced the SDRAM chip two days ago and the and I have had no failures since and no more error messages.

Glad to hear you fixed it. I always hesitate to advise people to buy new Ram because it they do and the problem still exists, then I guess they feel like I just cost them $$$ for something that was fine. In reality bad ram probably causes a good 25-30% of the problems people experience. I just try to exhaust all other possiblities and hope they come to the decision to buy Ram on their own after we have tried everything.

BTW, your problem is not that rare. MS actually has a KB article explaining that some programs that ran fine under one vrsion of Windows, but may not under another version due to the different ways each version uses memory.
