Http.TestConnection problem with Norton Internet Security

[ie02352]

Hi
Did anybody have any issues using Http.TestConnection on a system with Norton Internet Security.
For Some of our customers the function is failing (returns false) so they are unable to get software updates.
Thank you

Hi ie02352,

Is it possible that some of these users have blocked your update executable from accessing the Internet inadvertently?

I would get them to look at which programs they have blocked from accessing the Internet and make sure that your update executable is not one of them.

Thank you Mark for your quick reply.
Unfortunately one of the users that I was working with is down in Florida.
But I will look into it.
Any suggestions as far as users who are in a corporate environment with specific Prosxy Server settings?
Thank you

Hi ie02352,

In TrueUpdate 2.0 all Internet communication is done entirely through the WinINet API, making it fully compatible with any corporate network hardware and software that supports standard Windows/Internet Explorer functionality. So even if a client is behind a proxy server, they should have no problems provided they are able to use Internet Explorer successfully.

In general you will not have to supply TrueUpdate with any proxy information, in those cases it will use Internet Explorers default proxy settings to try to connect to the Internet.

Hi Mark,
I am working with a user who has the following setup:
Windows XP
He uses IE to connect to the Internet (No Problems)
It's a small office with MS small business 2000 server (Current SP)
MS security + Acceleration server (ISA 2000)
Firewall client-web proxy client

HTTP.TestConnection is returning false all the time.

I sent the person a modified version of our TrueUpdate files with multiple calls to HTTP.TestConnection (I was trying to determine if it is a port or a timeout issue) as follows:

IsConnected = HTTP.TestConnection("http://www.hartfordinvestor.com", 20, 80, nil, nil);

-- if no connection, test common proxy server port = 8080
if (IsConnected == false) then

--Test Messages ...
--REMOVE
Dialog.Message("Testing for a Connection", "Port = 8080; Timeout = 20 secs" );


IsConnected = HTTP.TestConnection("http://www.hartfordinvestor.com", 20, 8080, nil, nil);
end


-- if no connection, try again ...
if (IsConnected == false) then
--Test Messages ...
Dialog.Message("Testing for a Connection", "Port = 80; Timeout = 40 secs" );
IsConnected = HTTP.TestConnection("http://www.hartfordinvestor.com", 40, 80, nil, nil);
end


The System gets into a Not Responding status after the second call to HTTP.TestConnection.

We have already disabled the firewall. Same results.

Any help is really appreciated
Thank you

I had a similar type of problem with Norton Personal Firewal 2005. When the update tool would run it would just freeze and the entire system would lock up.

In the end it turned out to be a problem with the firewall - could not even manually add the applications. As an additional pointer which might help I was getting ccApp errors when turning the computer off.

This is something Symantec are aware of and one of the steps thy suggest is to clear the temporary files folder as some of the files the firewall uses in there may be corrupt.

I was having other problems with the firewall as well but the issue ith the Update program is fmiliar. In the end I uninstalled the firewall, cleared the temporary files folder then reinstalled Borton.

Hope this helps - and that you do not have to go as far as I did to fix it.

Thanks for the information KevinD, hopefully that will help a lot of people.

ie02352, you might also want to check and see if HTTP.TestConnection() is returning an error using Application.GetLastError() directly after it. If it is returning an error add a call to HTTP.GetHTTPErrorInfo(), this will provide you with some additional information that may help us figure out what the problem is.
