    I hadn't seen that before, though I spent 4 years trying to make a SBS4.5 network do anything at all correctly. Worst technical recommendation I ever made... I'd really like to find a solution that doesn't require renaming the internal network, as that has a lot of repercussions I don't want to deal with. Surely there's some way to accomplish this - it isn't that unusual a situation. If nothing else works, though, I guess I'll have to resort to doing so.

    There is nothing special about the port. It is just a commonly chosen port of 443 for HTTPS and 80 for HTTP. If you want to make a non-secure connection then you make your connection and don't negotiate an SSL session. Of course the server you connect to must be expecting a non secure connection, which most do. Let's say you want to connect to codeproject from your browser. If you were to connect directly from your application, it would open a TCP connection via port 80 and send something similar to the following. GET / HTTP/1.1 Accept: */* Accept-Language: en-us User-Agent: Your application name here Host: www.codeproject.com What will be returned will be the contents of the page requested. You can test this using telnet. Open a telnet session to your own server on port 80 and type the above text. End the text with two carriage returns to get the results. Now if you wanted to do the same request via a proxy you would do something like this. GET http://www.codeproject.com/ HTTP/1.1 Accept: */* Accept-Language: en-us User-Agent: Your application name here Host: www.codeproject.com There is very little difference. In this case you supply the host and protocol portion of the URL instead of just the path. This is because the proxy needs to know the name of the host you want to connect to. Instead of connecting to port 80 on codeproject you would connect to port 80 on your proxy server. Of course your proxy could use any port you wish. Port 80 is the standard, but it could easily be 8080 or some other port of you chosing. If your proxy understands other protocols such as https, ftp, gopher, or a custom protocol then you could use those by simply modifying the URL passed.

Got any good articles/guitlines on the subject? You can create a custom action for your MSI installer, simply by creating an "Installer Class" (select it from the File/Add New Item). IIRC, there is a sample for creating a database in a custom action on MSDN, but sorry, I can't remember where now. My latest article: GBVB - Converting VB.NET code to C#

    If the gateway IP is set to the local port of the router, and the XP box is on the same subnet, IE should have no trouble connecting. In Tools/Internet Options/Connections, there should be no connection information. Click on LAN Settings, and make sure that no boxes are checked - the Automatic and Proxy options will interfere with the box working properly, in particular. I haven't used the Home version - it's so badly crippled it isn't worth considering - but I'd also suggest that you review permissions for the user account. There may be a new one that restricts access to the Internet. Also, many OEMs preconfigure Windows with what they think most users will want. If yours has ICS installed and it's not acting as the gateway for your network, get rid of it, along with that stupid excuse for a firewall that comes with it.

    It seems to be just the normal NetBIOS announcements. I expected that to be in a separate service, but ntoskrnl is the source reported. It would be so nice to have a reference to the functions that all these various processes in Windows perform, and why they're needed... "Please don't put cigarette butts in the urinal.

    On Windows: netstat -a This will list all connections and listening ports. As far as opening and closing ports, that depends on what services are running and/or any software running at the time, or software you create that opens its own ports. If you want to make sure things don't go outside your "protected" network, setup a firewall ;) "The greatest danger to humanity is humanity without an open mind."   - Ian Mariano - http://www.ian-space.com/
