Good day all, i am a new fairly new 

 user with my DNS 323, i have an issue, first of all love my DNS, but i seem to have somehow locked up access to it, my grandson was helping gramps!
word of caution watch closer what they do at your computer  , i was in the configuration menu and setting a user name and password, now i cant access it. i cant seem to find any info on the website to cover this situation   i am really hoping to be able to access the device and not lose the data already on it. as a note i have 2 750  gig seagate drives  set as 2 volumes and i have no where else to put the data thanks in advance
