Inventory/scan failure

I have just a single machine (out of 10) in which I get a scan failure when doing inventory. I've tried uninstalling the agent and reinstallling, but get the same results. I am using build 50010 and the application log on the client machine shows and app error that dcinventory.exe faulted etc. In looking at the scan logs, the devicescanlogger.log seems fine; all results are listed and the final statement states that it's posted the data to the server. The error.log shows a handful of notices about child processes, followed by these three errors.

[Wed Sep 26 10:07:59 2007] [error] GET
[Wed Sep 26 10:07:59 2007] [error] GET /devicescan?servername=10.10.0.40&serverport=8020 HTTP/1.1
[Wed Sep 26 10:07:59 2007] [error] bin\dcinventory.exe 10.10.0.40 8020

Any help would be greatly appreciated!
