Doing the crypt yourself is a bad idea (I did this). Every time we've had to get on the phone with them, they would NOT accept that the first two characters of the password were not the same as the first two characters of the encrypted password. We have to go back and find the encryped version and give them the first two characters of that. This also means that anyone with your encrypted password can probably call up and have changes made (since they know what NetSol believes is the first two characters). -- Chris Adams <cmadamsat_private> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble.
