A definitive answer would be in a packet capture. This is an example of a similar scenario with a different NAS server that was filtered for SMB traffic:
The request is attempting to attach DLPe's extended attributes (i.e. tag data):
EA: MCAFEEDLPATTRIBUTES := OPG?...
Next Offset: 0
EA Flags: 0x00
EA Name Length: 19
EA Data Length: 3080
EA Name: McAfeeDlpAttributes
EA Data: 4f5047a1050000000000000346020000ed56db6adb40103d...
NAS server response:
NT Status: STATUS_NOT_SUPPORTED (0xc00000bb)
SetInfo Response (0x11)
[Class: FILE_INFO (0x01)]
[InfoLevel: SMB2_FILE_FULL_EA_INFO (0x0f)]
Ultimately, it is an issue with the NAS server is handling/rejecting the extended attributes request. You can remove the tags from the files and then try re-transferring to the NAS or disable the EA option in your policy to confirm.
Hi I'm getting the same error when copying certain files to our Hiatchii NAS. Did you ever find out what was causing the 0X80070032 error. Thanks
