Failed to Download Server Data

I have been having difficulty launching discovery jobs on one of my probe servers.  I can see that it shows up as "connected" however when I go to the logs I see the following error.

[WARN] [ProbeGW: DB Tasks Distributor] (DiscoeryClient.java:870) - failed to download server data (discoverResources/reg_mam.exe)

java.io.IOException: No ZipEntry found.

Any ideas?
