SMB/CIFS

[StanFabInd]

I have a Synology DS 1513+ running 4 teamed LAG 802.1ax to a Netgear G724ts-3 network switch and a number of Windows 10 clients  mounting it. since I upgraded to windows 10 i have been have huge issues with mounting and delays opening directories. it always mounts the mapped drives and always opens directories, but here are sometime up to 30 second delays from attempting to open a directory and it actually doing so. Has anyone else experienced this? Any proposed solutions? 

All Windows machines are kept current on updates and the Synology box is running the latest DSM with SMB 3.0 enabled.

First try disabling SMB 3.0 on the NAS. Could be a bug in SAMBA causing the issue. Mac's used to have similar issues with SMB 3.0 and also way back when SMB 2.0 was first introduced.

 

If you can disable it on the NAS disable it on the client. If the problem goes away when using SMB 2.0 then log a support case with Synology.

Thanks for the tip, however, I enable SMB 3.0 to try and fix the problem. I have also started a case with Synology, however,I also wanted to pursue a Windows solution as this is in an office environment and impacts productivity. 

Any other tips?

Not sure how much useful testing can be done on this without help from Synology.

 

Could run a wireshark while browsing a share and look for abnormal SMB traffic. Create a new test share with very open permissions (Everyone Full access Share and NTFS perms). Look in the client event logs for Audit Failure events.

 

Things listed above really are grasping at straws, the most useful one would be the open share test.
