I should have specified in my e-mail that I was using direct queries and not broadcasts. Sorry I forgot that detail. It turns out that there is a problem with a router here. The packets were getting from the xxx.xxx.87.0 to the xxx.xxx.86.0 network just fine but packets from xxx.xxx.86.0 were not getting to xxx.xxx.87.0. The network administrator moved the Windows machine over to the xxx.xxx.86.0 network so the machine could connect via the X server. I guess the answer to my question is that it should work, with direct query, as long as the routers are functioning properly. Thanks again. > At 01:23 PM 2/6/03 -0600, Glenn Johnson wrote: > > >I have a Windows XP machine at work that I am trying to get an > >X11 server to connect to a FreeBSD machine.
