That can be tested easily: Try switching off UAC, see if it works then. If so, we'll know in what direction to look...

Unfortunately it made no difference. I disabled UAC completely, rebooted the Win7 system. The ran the webserver app. Same problem. :(

I'm going to take a look at TIOStream's code, or try and use TIOStream directly, and see how that code. Damn Windows! ;-)
