My company is using windows 7 with IE8. And we are using automatic configuration script in our existing environment. But we encounter a problem with buzzsaw during the download process. When we try logon to projectpoint, we can success to download any files few times. But after few times trying, The connection is lost. We have open a case to Microsoft and they have done some investigation.
Here is Microsoft summary:
Contact application vendor to modify the code to open an internet handle using InternetOpen with the parameter dwAccessType to be INTERNET_OPEN_TYPE_PRECONFIG(0) not INTERNET_OPEN_TYPE_PRECONFIG_WITH_NO_AUTOPROXY(4)
