source: trunk/sources/HeuristicLab.Grid/ServerForm.cs @ 765

Last change on this file since 765 was 765, checked in by gkronber, 12 years ago

quick fix for #361 (19*19!) (GridServer doesn't work on Vista when IPv6 protocol is installed).
We should really find a better way to automatically determine an external IP address of a host.
