What do you mean by making changes? Logging into the server desktop for any reason is unsupported. What exactly are you doing?
I have to unplug my router and start it up again and then everything is ok until I make a change again. I just purchased my HP EX485 and home schooling myself using all the forums. These things are beyond valuable since the documentation from most manufacturers sucks mightily. Anyway, I was wondering if this problem might not be due to not having a static ip set up. I have read that is one of the first things you should do and I thought it was because everytime I put that ip in my browser it recognizes the site as long as I am looking internally. When I use my company's server to remote into the site, it won't bring it up until I jump through the unplugging everything hoop. Any thoughts?
As long as you aren't logging into the server desktop to make your changes, you should call HP for support.
