Consistently getting these 3 work folders errors 9001,9002 & 9004 on the client side. I’ve played with GPO, the file server, and every work folder setting I can find to no avail. Google searching hasn’t yield anything either, mostly just brings up a Microsoft result about somebody having this issue with no solution being posted and several articles that have solutions that don’t do anything for me.

I have even gone to the lengths of building a brand new lab from the ground up in hyper V and I get the same errors.

Windows Server 2022 clean install fully patched on both the DC and file server

Tested on Windows 10 and 11 clients.

For security reasons OneDrive Business is out of the question. Want a completely on prem solution.

Any suggestions would be appreciated.

9001 = Credentials required for the user.
9002 = Work Folders detected a sync error. Check partnership status, network connectivity, and disk space.
9004 = Your PC doesn’t comply with your organization’s security policies.
