Client's server is SBS 2011. Since they had Remote Web Access on a previous server, they asked for access for a single user on this server. When the user goes to the Computers section and hits the "Connect" button, nothing happens, but the Event VIewer is filled with these error messages. The server has 32 GB of memory. The old server had only 16 GB memory and this service was apparently working well. Obviously a configuration issue, but my web searches have not so far been helpful. The last time I worked with SBS was 2003 and I am extremely rusty (and wishing I had never taken on this particular customer).
