1 ) I tried a network install and found following. DNS server entries are greyed out even if DHCP server didn't supply a name server. 2 ) I could not connect to an existing FTP server using our corporate proxy ( wingate ) installer would respond "Bad server response" 3 ) I could not find any error messages anywhere to find what kind of "bad response" the FTP server gave.
I was able to replicate this problem in our test lab. 1) DHCP was configured to not give a nameserver IP address. The installer would not allow a primary or secondary DNS server address to be entered manually. Only IP numbers could be entered into the ftp server field after that. 2) We do not have a Wingate machine running to test this. 3) Console F3 does not give any indication why ftp was failing due to name services not being available.
Changed for next release.
