I have been having some problems with my Windows Home Server. The 20GB system disk has been filling up. When this happens various programs get unstable (Can't connect to the console, Squeezebox Server crashes, ...)
I RDP'd into the server and then took a look for where the disk space was going. I found that the log files from the DynDNS client were taking 8GB of space. Once I deleted the log files, everything started working well again. I will try to see if I can disable the logging the client.
