The ispconfig admin user is not related to a Linux system user at all. Normally you do not have a user with the name 'admin' on the shell, so I guess you might have mixed up usernames here. The username with administrative priveliges on the Linux shell is named 'root'.
ok, so what would normally stop putty from being able to login via ispconfig admin user? I was able to login with that user but now cannot
It is impossible that you have logged in with ISPConfig admin user using putty in the past. You might have created a shell user with the same name but you could never have loggid in using the ISPConfig admin user.
