Event ID 2021

Question

_{Wednesday, February 10, 2016 3:33 AM}

I have a media server running Windows 10. It only is used for media and connects to a media device with an SMB share. I keep getting event ID 2021 The server was unable to allocate a work item (#) times in the last 60 seconds. I've read this article and tried what they suggest on the registry edit https://support.microsoft.com/en-us/kb/317249

I still get this error. It seems to not always cause a problem when the error shows up but sometimes my movies freeze. I notice this only happens when I play blu ray iso files and not dvd iso files as I'm assuming it's due to the higher bandwidth needed on blu rays. 

I've changed nics to see if that fixes my issue. Still doesn't fix it. I do notice however when the movie freezed my hard drive Active time jumps to 100% I am using Windows Storage spaces and am using 7x5TB seagate drives. I've fully tested each drive and found no issues with them.

Any ideas on how to get rid of the 2021 event?

Forgot to add I have 8 gb of ram and a intel pentium g4400 cpu and this is only a file server nothing else. Cpu is pretty much idle and I never use more than 2GB of ram on it.

Thank you

Hi,

Have you tried to configure the SMB settings to check this issue?

1.

1. Run PowerShell as Administrator

2. Set-SmbClientConfiguration -RequireSecuritySignature 1

Answer Y when prompted to confirm the modification.

3. Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters" RequireSecureNegotiate -Value 0 -Force

2.

Control Panel / Programs and Features / Turn Windows Features On or Off and make sure SMB 1.0/CIFS File Sharing Support is ticked

Just an update I moved a iso file of a movie off of storage spaces and onto an ssd. I still have the event ID 2021 occuring. So i don't think it's a storage spaces or a drive issue.

Any ideas?
