# Can't connect to Hyper-V shared storage on Windows Server 2016
15+
16+
This article provides guidance for troubleshooting connection issues that involve shared storage in a Windows Server 2016 Hyper-V environment.
17+
18+
## Symptoms
19+
20+
You experience connection problems such as the following issues:
21+
22+
- You can't use Hyper-V virtual machines (VMs) to access or connect to shared storage.
23+
- VMs that rely on shared storage don't function correctly.
24+
25+
These scenarios don't generate specific error codes, which makes the issue harder to diagnose.
26+
27+
## Cause
28+
29+
Such connection issues are most likely related to one or more of the following causes:
30+
31+
- Shared storage settings aren't correctly configured within the Hyper-V environment.
32+
- Virtualization-specific settings aren't correctly configured in Windows Server 2016.
33+
- Network settings such as storage paths aren't correctly configured.
34+
- Network connectivity is interrupted.
35+
36+
## Solution
37+
38+
> [!IMPORTANT]
39+
> Before you start troubleshooting, make sure of the following:
40+
>
41+
> - You have Administrator-level permissions for the Windows Server 2016 computer.
42+
> - The Hyper-V role is correctly configured on the computer.
43+
> - The computer meets all relevant hardware and software requirements for shared storage. For more information, see [Windows Server storage architectures with Hyper-V](/windows-server/virtualization/hyper-v/storage-architecture).
44+
> - You are familiar with how to configure Hyper-V and shared storage environments.
45+
46+
To resolve the connection issue, follow these steps:
47+
48+
1. Check your shared storage configuration. Make sure that the shared storage is correctly configured and accessible within your Windows Server 2016 environment.
49+
1. In Hyper-V, check storage path settings.
50+
1. Check the network interfaces and switches between the computer and the shared storage devices. Make sure that they are correctly configured.
51+
1. Make sure that the computer successfully connects to the shared storage devices.
52+
1. In Hyper-V Manager, check the configuration of the VMs. Verify that the VMs correctly map to the shared storage.
53+
1. Make sure that the shared storage is online, and that the computer can access it.
54+
55+
If the issue persists, collect the following information and then contact Microsoft Support.
56+
57+
- Notes that describe any adjustments that you made to the configuration and any observed changes in behavior.
58+
- Any events from the Event Log that might relate to the issue.
59+
- Results of any additional diagnostic tests that you have run on the system/
