I've just loaded a fresh 5.1 MSS image on my S3500 Server and would like to use the configure from DCT file option to set it up. My file is on a FAT32 USB named 'mm51.mmdct'. The MSS sees the file name, but when I select "Fresh Configuration", it comes back and tells me the maximum DCT file is 100,000 bytes. My file is 503,000 bytes. I did this with a 4.0 system and a DCT file of 490K and had no problem. I've rebooted the MSS and tried two different USB fobs to no luck.
