Hello there!

I have a running Windows Server 2019 used as a File Server.
He is having a problem: When reading/writing files via network share (SMB Protocol) the request takes a long time to complete...

This is happening on Office 97-2003 files, PDFs, Solid Works archives, and some other extensions.

Things i tested:
1. HARDWARE - HD, NIC, CPU, Memory. All returned good and positive results... No phisical problems
2. Network: Internal connection and external is OK. Low latency. No loss.
3. Tried accessing those files LOCALLY only - Problem didnt occur.
4. Created the SAME structure using ANOTHER server on the same network - Same OS (Win SRV 2019) with even the SAME BUILD! Problem DIDNT happen.

So, basically this problem is just happening on that specific server. I have no idea on what to do Link Removed
Does anyone went through this and can give me a little help? A light on the end of the tunnel ... Link Removed

Thanks in advance...

Try forcing it to use a different smb version.
Also look at the antivirus.
Or the most obvious option would be rebuilding your file server on top of a new virtual machine. That seems to be an easy fix, actually.
Have you tested the network throughput and disk performance?

Yes.

Didnt returned any problems...
 

Make sure LSO is disabled on the NIC
