I have a user who recently switched to a new Win7 PC.  

First they reported problems using gotomypc to remotely access the new PC.   gotomypc claims intermittent internet connection at host PC.  

I did a test last night, I had gotomypc, AND logmein open to the computer in question, from the same client.  gotomypc froze and showed the error, all the while, logmein was working fine AND a constant ping on the host to google, was running fine the whole time with times around 20ms.  

The user also just reported that he is having problems with web pages too.  Saying web pages will often take a long time to load, or get hung up.  

Any ideas?

It is looking like an issue caused by CA internet security....  I had it installed ONLY for Antispam.  Only the portion with the antispam and firewall were installed, and the firewall was even disabled.   But still seems to have caused problems, cause after uninstalling it -- no problems.
