I have a test and prod server running Server 2008 R2. Both have an IIS/FTP site setup. both are using the same credentials, on the same ports, talking to the same destination.
For some unknown reason I can connect to test without issue, but if I use the same credentials in prod it instantly bounces back with error 530 login.
The difficulty is that from a permissions standpoint its the same account being used against the same destination.
I've looked as much as I can and I can't find any reference to the account in question of having extra access on test vs prod, nor can I find anything related to credentials used through the FTP/IIS site.
So my question here is where should I be looking to find out what why an account is kicking back a error 530 in prod, but not in test as I can't find anything related to actual accounts in the configuration.
