I’ve seen this error several times within our company and it seems to occur due to the short time-out feature for IE7 to return data. When compared to IE 5.x and IE 6.x which had a 30 minutes timeout and now IE 7 reduced to 30 seconds; As a result Internet Explorer doesn’t wait too long for data to come back if there’s a delay.

The good news is that there is a solution that’s worked wonders for me. In addition to this method below I would suggest updating SmartView to the latest version.

On the clients machine you need to find the following registry folder:

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings]

Then create within the folder the following 3 keys:

“ReceiveTimeout”=dword:00dbba00

“KeepAliveTimeout”=dword:00180000

“ServerInfoTimeout”=dword:00180000

If you are still getting the timeout error your connection maybe slow and you could try increasing the KeepAliveTimout.
