Any diagnostics for read only on SMB

retag add tags

Afternoon, I have read only file issues on a application. My suspicion is its the client application / machine cashing the file status incorrectly Server side there are no file locks SMB share does not permit sharing

I have done some preliminary testing and I Can seen file read, & trite requests with wireshark. I'm wondering can / should i see any server response saying read only / write deny ?

Are you capturing the CREATE Request/Response packets?
Microsoft specs: 2.2.13 SMB2 CREATE Request
File access permissions: 2.2.13.1.1 File_Pipe_Printer_Access_Mask

Is the application making a request to write to the file then getting a CREATE response?
