I am trying to connect my linux machine to an ADS server,but when i give the command
net -I <ipaddress> and -U <username> join

I am getting the following errors

<time/date stamp>
rpc_client/cli_netlogon.c: cli_nt_setup_creds(249)
cli_nt_setup_creds: request challenge failed
<time/date stamp>
utils/net_rpc_join.c: net_rpc_join_newstyle(326)
Error domain join verification (reused connection):
NT_STATUS_INVALID_COMPUTER_NAME


I am using the samba version 3.0.8.0.pre1.3

Can anyone figure out why this occurs..????
