Simon,
Thanks. I've confirmed with our Networking group, and it does
seem that something was misconfigured, or missed. I'm waiting for a
test job to run and see if the speeds are any better. Lately, this one
has ran at 18K/sec. We'll see. I'll let the list know what I find, to
either 'close' the issue or offer more info.
As for the Master/Media servers, nothing odd outside of needing
an occasional reboot to refresh.
Thanks,
Jason
