Rnaapp, Msmsga & Explorer Illegal Operations!

[FZWG]

Appreciate some assistance.

In the past few days the PC keeps showing all these prompts for either Rnaapp, Msmsgs or Explorer, and the famous "This program has performed an illegal operation and will be shut down."

Have not installed or uninstalled anything lately. Can't seem to figure this out.

Are Rnaapp, Msmsgs and Explorer items from one particular application?

Any ideas of what the problem might be?

Best of all, any suggestions to get rid of these prompts that keep showing up?

some system spect would help here,
my first thought would be ram problems.

Rnaapp is your dialup connection - msmsgs might be MSN Messenger.......does this give you a clue?

glc, bailey,

Thank you for your replies.

Got the clue!

Have a feeling MSN Explorer or MSN Messenger are the culprits.

Would running System File Checker identify any corrupted or missing files in this case?

Nope, msmsgs is the internal windows program that puts a message on the screen, and plays a sound at the same time. If the sound file is corrupt, or not in the correct path, you get the error. Open "Sounds" in device manager, and remove (change) the sound scheme. Restart, then you can change it back, and the path problem will be corrected (usually).
The rnaapp problem occurs when the modem is told to disconnect from the internet, and appears to do that, but windows will not release DUN. A simple uninstall and reinstall of DUN usually cures that, although sometimes a modem driver reinstall/upgrade is required.
Both of these problems will cause Explorer to appear as the culprit, when there's nothing wrong with Explorer.

reboot,

Thank you for your reply.

Followed you just fine, until you got to DUN. Appreciate knowing what DUN is, and how you go about uninstalling and reinstalling it?

[reboot]

DUN=dial-up-networking. It's in Control Panel, Add/Remove programs, windows setup tab. Remove it, restart, reinstall it.

Well heck. Where did my brain go?

Thanks again, reboot.
