2012 R2 File Server Access

I recently upgraded a File Server to Windows 2012 R2 Datacenter. Everything went well and worked fine for weeks.

A couple of days ago I enabled de-duplication on the server. Now, I have one XP Professional Client and three Sharp MFP machines that cannot access the file server, or any of the SMB shares on the server.

When we try to scan to a network folder we get a send error code 80-0000.

I know that others have seen this before, but I haven't found a resolution to this issue. Any assistance would be greatly appreciated.

Thank you,

Make sure the SMB1.0/CIFS feature is installed. Most MFPs nor XP can talk SMB2 or 3. I'm guessing it got removed around the same time dedup got turned on.

I have confirmed that SMB 1.0/CIFS is installed.

When browsing from the XP machine, I can see the file server, but none of the shares. It's like network discovery is not enabled, but it is.

I have set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\LmCompatibilityLevel value to 0 so that the file server will send LM & NTLM responses.

I have tried to get an error to present itself in the logs, but the XP client can't even see the shares to try and connect to them.
