I too am having the same problem of McAfee unable to access the Internet.
Out of the blue, McAfee told me I had to Fix problems. Then it said it couldn’t fix the problems and it instructed me to download a new copy. I downloaded DMSetup-Serial.exe and it throws an error:
Internet Connection Unavailable – We can’t download your McAfee software because we’re having trouble accessing the Internet. Please make sure your computer is connected to the Internet, and then try again.
According to the McAfee Virtual Technician, there is one problem that McAfee cannot resolve and that is, “Unable to download files from McAfee server.” In the Diagnostic Log, two files are incorrect: Excluded Files Present
C:\Documents and Settings\...\Cookies\*McAfee*.*
C:\Docume~1\...\Locals~1\Temp\\*
…and three Systems are incorrect
Clear DNS resolver cache
Unable to download files from
http://download.mcafee.com/products/mvt/xmlfiles/connectivity_test.txt Temporary internet files need to be deleted
I’ve opened four cases (each the same issue) with McAfee in hopes of connecting to an online Tech, but the GoToAssist program (the chat app) seems to be stuck initializing. So here I am.
Other things I've tried...
<> Cleaned out cookies, Temp Internet Files, and all temp folders. I have 3.6 GB of space left. I’ve even reset the IE settings to default.
<> Run both superantispyware & malwarebyte’s programs. They found nothing.
<> Edited the hosts file to include the following…
69.299.33.21 bin.mcafee.com
120.30.243.19 nai.com
<> Entered Safe Mode and deleted the C:\Program Files\McAfee\VirusScan\DAT directory contents.
<> Removed all checkmarks from my LAN Settings in IE7 and even downloaded IE8.
As McAfee is my firewall and virus software, I’ve done all of the above both with and without Windows Firewall enabled.
System: Lenovo R61 laptop running Windows XP SP3
I obviously have Internet connection. What could be causing McAfee to think otherwise? (BTW, on a different PC in my house, McAfee is working fine!)
Any help greatly appreciated!
