It would require some sort of remote management program, so best to clear that with the IT people at work first, before you go trying to install software on a work computer. You should also consider the security implications of having such a program running on your home system.
When at work, maybe you should just use something like Google Groups. It may be less than ideal, but it's functional, and it saves having to clear things with company IT and exposing your system to the potential security risk of a remote login. All it requires is a web browser, which presumably you already have on your system at work.
I have optonline as my internet provider at home. Connecting to Newsgroups works fine from home when I am connected to the internet through optonline.
When I try to connect to newsgroups at work using the NEWS.OPTONLINE.NET that works at home, it doesn't work. When I called cablevision, they said unless I'm connected to the internet at home (cablevision recognizes the IP address as their's from home), I can't get access to the newsgroups.
Does anyone have a work around to this?
