Forgive me if I'm posting this in the wrong place, but I believe this is a security setting. Since Vista was released (this includes Vista, Win7, Win2008 R1/R2), I've had trouble running EXEs on network shares that open connections to other servers. For example, SendEmail.exe doesn't work if run from a network location if I target an SMTP server other than localhost. I'm trying to find out if I can disable the security "feature" that is blocking outbound connections from being opened by an EXE run from a network location. In an attempt to troubleshoot further, I enabled the Microsoft-Windows-Winsock Network Event/Operational log. The error that is logged when the outbound connection is block is shown below.

disable the firewall on the Vista computer and the target servers.

The firewall is already disabled. Also, it works if I copy the EXE locally and run it. It doesn't work if I run it from a network location.

I have this problem when running from a Win2008 R2 server as well as Vista PC and Win7 PC.
