Hi,

DS918+ (x3)
Windows Server 2016 Domain
50+ users.

This problem started for me about 2 weeks ago now.

It became worse after a series of forced MS updates that also included some server updates.

I have one share created accessible to all domain users with no special permissions.
We don't execute files directly from the share the workload is relatively minimal.

As mentioned in a previous post, a restart of the NAS does not fix this issue.
Nor does rebooting our DC.

Fix's so far:

1. Removing and re-adding the NAS to the domain
2. Releasing the client IP from the local machine, deleting them from DHCP and the refreshing their IP

These are not business level products by any means.

See my recent post on this forum: https://forum.synology.com/enu/viewtopi ... 5&t=144502

In short, you'll need to add all the DC IP or FQDN into this list (v6.2). I'm not experiencing this with the versions before 6.2.
Control Panel > Domain/LDAP > Advanced Domain Options > DC IP/FQDN
In that list, put in a comma separated list of IP/FQDN's of your domain controllers.

Hopefully this helps.

-Paul

Thanks Paul, I'm going to attempt to enter this information in from our SysAdmins and see if that resolves our issue.
