FC5 network installation failed .. (((

[I_one]

I install FC5 from my ftp server. I burn boot.iso on CD and boot my system from it.
Installation starts ... network (dhcp) detects ... grafical interface starts ... everything is ok.
Installation fails after formatting partitions with message some 'Cannot find bla-bla-bla.rpm'. RPMS folder is fine and have all rpms (2207).
Timeouts on my ftp server is sets on 30 minuts ... I dont' know what to do ... Is it installation program bug ?

P.S.: FC4 network installation from my ftp server was fine.
