    File transfer error and lag 0x8007003B

    Hi !

    I am having problems with file transfers from my PC to my NAS. I do not have this problem transferring files from a drive on my pc to another drive on my pc, only to the NAS. I am getting some serious lag with small files and error's with big files.

    If I try to transfer a small file, the transfer window appears but it takes a couple of seconds to start (maybe 10 seconds or so).

    If I try to transfer a large file (a couple of Gb's), the transfer window appears but I get an error (0x8007003B) and the transfer fails.

    Now, this is what I tried to fix the problem ;

    - Disabled Fire wall
    - Disabled Anti Virus
    - Uninstalled Anti Virus
    - Reverted to an older Firmware on my router
    - Reverted to an older firmware on my NAS (QNAP 469 Pro)
    - Disabled the Teredo adapter (netsh interface teredo set state disabled)

    I am all out of ideas.... This problem just came out of no where, not firmware update was done on the router or the NAS when the problem appeared.

    Any help would be appreciated

    Well, managed to fix it. If anyone has a QNAP NAS, it's a problem with the latest firmware update.

    This is the link to a fix until QNAP releases a new firmware.

Incredibly slow file transfer
It starts at around 300MB/s but after a second it drops to 20MB/s. On Windows 7 it was usually around 100MB/s. This is for transferring to second hard drive. It's even slower transferring to USB drive, about 2 MB/s.
