I'm running putty from a Win 7 client and receiving a "Server unexpectedly closed network connection" message immediately after logging in. I turned off the firewall, but that did not help. Any suggestions?

Does this happen to all clients running Putty? See if you can test with another client and if it is happening the same then could be something happening to the system. You might want to look at the critical error logs to see if there are any alerts.
Unfortunately, I can't try connecting from more than one system. I'm using Logmein to connect to a Win 7 system on a yacht, then I use that systems browser to connect to the NAS-R3.
