Formating DB's for BLAST on NT

[rjacob-nospam at itsa.ucsf.edu]

I'm trying to set up an in lab BLAST server on an NT box using NCBI
BLAST version 2.0. I've unpacked the programs and downloaded a few
databases. For BLAST to use the database it needs to be formated with
the "formatdb" program. Unfortunately I always obtain an error:

================[ Dec 11, 1998 11:45 AM ]========================
Version 2.0.6 [Sept-16-1998]
Started database file "D:\Blast\ecoli_aa"
FATAL ERROR: [067:001] FindPath failed
FATAL ERROR: [067:000] Failure to read sequence. FastaToSeqEntry()
failed.

Formated 0 sequences


Does anyone have any clues to what I might be doing wrong or not
doing?
The databases used are amino acid databases in FASTA format from the
NCBI. I've tried variations of all the options in "formatdb" to no
improvement. The documentation I have read did not mention this
problem or any other special procedures that i must do before using
the database.

Thanks in advance for you help.
