Hi,


I recently migrated from a 2019 file server to a 2022 OS. Users began experiencing slowness in Excel files.

I did not use the same hostname and IP address as the old file server.

I am using a new hostname and a new IP address.

The server is running on VMware.

The Windows firewall is disabled.

Trend Micro Endpoint Security is running as AV on the server.

When I checked the event viewer on the server,
There error I'm getting on the File Server is:////////SMBServer-Operational//////


Reopen failed.

Client Name: \\10.10.10.3
Client Address: 10.10.10.3:61372
User Name: CONTOSO\user
Session ID: 0xAC0074000C81
Share Name: SHARE
File Name: IT\test.xlsx
Resume Key: {341104c5-a5d2-11f0-bbd0-38f3ab75ca9e}
Status: Object Name not found. (0xC0000034)
RKF Status: STATUS_SUCCESS (0x0)
Durable: false
Resilient: false
Persistent: false
Reason: Reconnect durable file

Guidance:

The client attempted to reopen a continuously available handle, but the attempt failed. This typically indicates a problem with the network or underlying file being re-opened.

Is this a File Server Cluster?

Search tells me it’s DFS-N.

 

We have two tiers in our DFS-N setups:

1: \\MyDomain.Com\DFSRoot (via DFS-N)

2: \\MyServer\MySharedFolder (direct)

 

Sage requires a mapped drive letter to #2. Most others can use a mapped drive letter to #1.

 

AutoCAD is another app that cannot use a DFS-N UNC mapped drive.

 

Check with the app’s vendor. I bet it’s not DFS-N compatible.
