I am experiencing crashes to desktop when I try to use the Mobotix Security software to playback footage across a SMB share in Windows. It is designed to work this way. Another symptom (probably of the same issue) is that when populting the recording paths of the camera's subdrectories (which should happen in a second or two over gigabit lan) is that this process takes about 1-2minutes when it should take a few seconds.

I captured the pcap files during this process, and I think they show a lot of retires, but I am not expert enough to interpret them accurately. The server is and the client PC is .5

The environment is Gigabit Lan. a synology NAS.

I have set one of the camera's to record to a spare ubuntu box with Samba and recordings are retreived just fine, so I suspect the Synology NAS.

There is no apparent error, or delay when browsing these shares in Windows file explorer.

PCAP here:

Can anyone please help?

Hi, without having the initial Sessionstart (3way handshake) captured an deep analysis makes not much sense. So could please try to capture a whole session which includes the 3way handshake?
