Hi friends, I have been using UDPCast successfully for the fast few months and it was successful. in most cases. But recently when I was trying to clone a 5.5 GB Partion from one machine to other machine ( of same architecture..both are dell machines, both have 256 MB RAM, Identical HDD geometry, Identical NICs). on the sender side after getting a few retransmission messages it kept on saying that nrBlocks=36 lastGoodBlock=0nrBlocks=130 Timeout notAnswered=[0] notReady=[0] nrAns=0 nrRead=0 nrPart=1 avg=3969 bytes=1 232 425 333 re-xmits=001037 (0.0%) slice=0036 1 232 425 333 and reciever doesn't give any messages. what does this message mean. Does it assure us a safe transfer ..if not how to rectify this problem.Any help is highly appreciated. Thanks, Sai __________________________________________________ Do you Yahoo!? The New Yahoo!
