I want to blast the sequences against my own database... So I am using standalone blast utility. while using update_blastdb.pl I have come accross the error of "Failed to connect to ftp.ncbi.nlm.nih.gov: Invalid argument".
Command: perl update_blastdb.pl --passive refseq_rna.00
Error: Failed to connect to ftp.ncbi.nlm.nih.gov: Invalid argument
Why this error?

As I suspected it's a windows problem with Net::FTP, possibly passive mode or options are not supported by perl or your version of FTP on windows this way. Try without switch --passive or try -passive, otherwise you have to download files manually or try a real operating system.
update_blastdb.pl --passive refseq_rna # use dbname not volume filename (refseq_rna.00)

works for me, maybe something wrong with your internet connection (check if you can access ftp.ncbi.nlm.nih.gov)? otherwise more details please: which operating system (windows prob.?) perl version etc. ftp version, etc, etc.
