I installed WHS & PP3 last week to use with my Win7 laptop and Vista desktop (will upgrade to Win7 soon). WHS was set up with remote access turned off, and by default, was issued a DHCP IP address from my Linksys WRT54G router (running DD-WRT). All machines connected perfectly, and got backed up for several days. I had this great idea to turn on remote desktop, and somewhere had read that WHS should be on a static IP, so I went through network connections, selected TCP/IP, and changed the DHCP to Static IP. Rebooted, and off I went...
Now the Win7 laptop (must stay as DHCP for roaming) won't connect to the WHS, yet the Vista desktop (static IP) can. I can ping the WHS from the Win7 laptop, so there is connectivity. I can also access the WHS from the internet using https://servername.homeserver.com, so I believe the router is configured correctly. I also tried re-installing the WHS connector software, but it couldn't find the WHS. servername:55000 was also coming up bad from the Win7 box (but fine from the Vista desktop).
