I get this error message when I try to open the "Phone and Modem Options" from "Start -> Control Panel". I also get this error when I try to add a modem device using Winfax Pro. I have uninstalled and re-installed WinFax Pro with no effect. I have checked the Symantec Support site but found no solution. I went ahead and did the following procedures to try to fix the problem:
1. Start -> Run -> sfc /scannow (re-install windows dll's)
2. Checked all Windows "Services" to see if something had been "Stopped" or "Disabled". I couldn't find anything related to communications or Modems. There are a couple telephony items of which I am uncertain.
3. I've run Spybot, Adaware, and AVG system virus checker. A couple minor "Viruses" were found and removed, but the problem persists.
The information on the web seems sparse when I search for "Phone and Modem Control Panel cannot be opened". The post in Experts-Exchange suggests re-installing the WinFax Pro application. This does not solve the problem. I do not want to run the XP Repair Installation option except as a _last_ resort. Suggestions appreciated. Thank you.
