Running IIS 6 on a windows server 2003 standard edition, i decided to try to connect to a running FTP server. Upon inspection of the server properties, all seemed to be in working order, but no matter what i did, i was met with the "530 Connection refused, unknown IP address."-error.
I noticed there were no questions or answers that were helpful to my specific problem, and none were readily avaliable via MS or even extensive googling.
The closest i could get to a satisfying answer was the webpage "Funny things computers say", which stated that this error message is lying through its teeth.
