Symptoms

You may experience one of the following issues:

You can see the shared files but cannot open them.
When you open a shared file, the loading progress bar is displayed as zero percent.
When you open a shared file or a folder, Windows explorer freezes.
If you try to restart the Server service, the service freezes in the stopping state.
Microsoft Office Access databases (.mdb files) that are hosted on Windows Server 2012 shares may be corrupted.
A "file is locked by another user" or "is locked for editing" error occurs in Microsoft Excel.
SMB2 dialect negotiation receives only a TCP ACK response.

To work around these issues, follow these steps:

Disable the leasing on the file server. To do this, run the following command:
```
REG ADD HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters /v DisableLeasing /t REG_DWORD /d 1 /f 
```
Note After you set this registry key, SMB2 leases are no longer granted, but oplocks are still available. This setting is primarily used for troubleshooting.
Restart the file server, or restart the server service. To restart the service, run the following commands:
```
NET STOP SERVER
NET START SERVER 
```
