I have being having trouble with the web server used for our intranet. It has some antivirus software on it that stops mass emailing.
So I wrote a quick C# winforms app, ran it on the server to try and send an email, and it failed. It was being blocked by antivirus on the server, I added the exe to the allowed list and it worked fine. I tried adding the service inetinfo.exe, which is the only one I could see related to IIS, and it doesn’t seem to enable the emailing.
Would asp.net code send the email under a different exe name? I have seen a reference to aspnet_wp.exe.
ASP.NET runs under ‘w3wp.exe’ on Windows Server 2003, and ‘aspnet_wp.exe’ under Windows 2000. So you’ll need to open up your scanner for those processes.
