How to fix Windows Error code "0x80004005"

Windows Error code 0x80004005 - What to do if the access to a network share is acknowledged with the error code 0x80004005? The hint from Windows about an "unknown error" doesn't really help - who would have thought that? Here I show you three possible solutions for the problem.

How to fix Windows Error code "0x80004005"


0x80004005 - Network error


When accessing network drives via the SMB protocol, the following error may occur:


Network error - xxx could not be accessed.

Make sure that the name is spelled correctly. There may be a network error. Click on "Diagnostics" to identify and fix the network problems.

Error Code: 0x80004005 (Unknown Error)


In this case, Windows has a problem with logging on, or connecting to the network path. This may be due to the following reasons:


the SMB protocol has been disabled

there is already a connection to the network destination

local permissions are not passed over the network

According to the motto "Reboot is always good" you should first reboot your Windows PC. If the error still occurs, you can follow the tips below.


Re-enable SMB protocol


Especially older NAS systems still use the outdated SMBv1 protocol. When using newer operating systems and installing current updates, the SMBv1 protocol may be disabled on the client. This will cause you to get the network error 0x80004005 when accessing such a share. Even though it is a security risk (keyword: crypto trojans) the SMBv1 protocol can be enabled very easily. You just have to open the Windows PowerShell with administrative rights and enter the following command:


Enable-WindowsOptionalFeature -Online -FeatureName smb1protocol
Confirm the security prompt with "Yes" and restart Windows. The SMBv1 protocol and access to such shares is now enabled again. Existing network connections trigger 0x80004005 Another way to get rid of the network error 0x80004005 is to remove all existing connections and then reconnect them. To do this, you must use either the Windows Command Prompt (cmd.exe) or Windows PowerShell. The following command will disconnect all existing network connections:

net use * /delete

After entering this command, you must confirm your intention once again. Windows then disconnects all network connections to any network drives that may be connected. You can confirm the success with the net use command. Now you can try again to re-establish the connections. The error code 0x80004005 should no longer appear.

Authorizations are not passed on

The reason for the error 0x80004005 could also be a missing permission. This is the case when you try to establish a network connection with a local administrator account to a share of another Windows computer. In this case the so-called Auto-Elevation of the User Account Control (UAC) does not take effect, which should actually pass on the permissions.

The remedy is to set a new entry in the Windows Registry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System] "LocalAccountTokenFilterPolicy"=dword:00000001


Again, a restart of the operating system is necessary.
