Yes, I'm running Microsoft Security Essentials on each of the Client machines. Not running any AV on the WHS. I can try disabling that tonight, but not sure why having the AV software blocking the traffic would result in the WHS getting into a semi-hang state.
One of the things I tried is disabling all of my Add-ins, done a cold boot, but that does not seem to help. I'm back with only my Squeezebox Add-in for now.
I did run the WHS Connector troubleshooter, and it was throwing both DHCP and DNS errors. I've got two of my 4 machines set up with static IP addresses, (the WHS box and the primary desktop), and the connector says I can therefore ignore the DHCP errors (which I did). I corrected the DNS error by adding the local router/gateway address into the DNS server address table for the IPv4 Properties on the network adapter for each of the two machines (before, I had only added the primary and secondary DNS servers from my ISP - Comcast - now I've got all three (local and two from Comcast)).
After making the above changes, I reinstalled the WHS connector on the primary desktop, but my Media Center Connector install still fails, and after failing, pretty much locks up the WHS, such that I need to force a cold reboot to get things working properly.
At this point I'm considering doing a Server reinstall, but think that might be overkill, and am also concerned that it might not fix the problem.
For what it is worth, my router is a Linksys WRT54G v2.0 w/latest firmware (which is pretty old at this point).
Thanks,
Tim
