Thanks again to all for the assistance you've provided.
Got another strange, remedial-feeling, but elusive problem on my hands.
Trying to backup our data is unsuccessful from multiple client machines - XP, Win7, 2003, 2008, you name it.
FTPing to the ICP 3300 is not successful. No rejection/drop message - just nothing.
Most of the troubleshooting info I've read starts from the point after successful connection to the 3300.
Anyone else dealt with this issue? I thought it was all about Windows 7 as the client machine, but I don't think so any longer.
