The error code 0x800704f8 turns up in a few places in Windows, which is why advice online looks so mixed. Its number converts to 1272 in plain counting, which Windows lists as a blocked guest logon: the system refused to let an unnamed guest into a shared folder or drive on another computer.
Some people also report the same number when signing in to an account or opening a built-in app. The meaning there is less clear, because Windows reuses general codes in many places. So the sensible approach is to match your situation to the right group of fixes below, try the safest first, and avoid any tool that promises to remove the code in one click.
Common causes
1Guest access to a shared folder is blocked

What fixes itShare to a named account with a password instead of guest
2Wrong or missing username for the other computer
How to tellYou are asked for credentials, or Windows silently tries as guest
What fixes itUse the account name and password that exist on the sharing computer

How to fix it, step by step
Note where exactly the code appears
Does it show when you open a network folder, when you sign in, or inside an app? The answer decides which steps below matter. For network folders, go to steps two to five. For sign-in problems, go to steps six to nine.
Open the share with a real username
Press Windows + R, type the path such as
\\PC-NAME\FolderName, and when asked, enter the username and password of an account that exists on the sharing computer. Tick Remember my credentials only on your own private computer.Share to a named user on the other computer
On the computer that holds the folder, right click the folder, open Properties, then Sharing, and choose Advanced Sharing or Share. Add a specific user and give the level you need, like Read. Avoid giving Everyone full access.
Clear old entries in Credential Manager
Open Credential Manager, go to the Windows Credentials list, and delete entries that name the other computer. After that, retry the path and type fresh details.
Check network discovery and the network type
Set your network to Private and make sure file and printer sharing is on. The steps are described in our page on error code 0x80070035, which is a close relative of this fault.
Restart the computer and install updates
Restart, open Settings, then Windows Update, and install anything pending. Sign-in related glitches are often fixed by an update and a restart.
Test with another account
Add a fresh local user from the Accounts area of Settings and sign in with it. If the problem disappears, your profile is damaged and moving your files to the new account may be the cleanest cure.
Run SFC and DISM
Run Command Prompt as administrator and type
sfc /scannow, and wait for the result. Follow it withDISM /Online /Cleanup-Image /RestoreHealth, then reboot.Use System Restore if it began recently
Choose a saved point dated before the trouble began. Personal files remain, though newer programs and drivers can be rolled back.
What error code 0x800704f8 means
Windows error codes that start with 0x8007 wrap an ordinary system error number. Here the number is 0x4F8, or 1272 in decimal. That value is documented as a block on guest logon in network file sharing. It is a security protection, not a bug: a modern Windows computer will not let an anonymous guest browse another computer by default.
You type a path to an old network drive and get You can't access this shared folder because your organization's security policies block unauthenticated guest access. Windows is protecting you. The fix is to log in with a named account, not to remove the protection.
Error code 0x800704f8 on Windows 11
The same code is reported on Windows 11 more often because newer releases ship with guest access blocked by default. You may find advice to turn on insecure guest logons in a policy setting. Treat that as a last resort for a closed, trusted home network, because it lets anyone on the network connect without a password. For office computers, never change it without your IT team.
If the code appears at sign-in or in an app
When 0x800704f8 shows on a sign-in screen, in mail or in a built-in app, the cause is not guaranteed to be the same as the folder case. Treat it as a general fault in your profile or system files. Restart, update, repair with SFC and DISM, and test another account. If a work account is involved, the message may actually come from a policy decision; compare with error code 53003. For other errors that share a similar number format, see the full list of Windows error codes.
Which fix fits which situation
| Where you see it | First fix | Second fix |
|---|---|---|
| Opening a shared folder | Sign in with a named account | Clear saved credentials |
| Network drive on a router or media box | Set a username and password on the device | Update the device software |
| Windows or account sign-in | Restart and update | Test a new user |
| Work laptop | Ask IT | Do not change policies yourself |
Do not install downloaded repair programs for this code. Use only the tools inside Windows, and back up important files before trying a new user or System Restore.
Frequently asked questions
What does error code 0x800704f8 mean?
In file sharing it means guest logon to the shared folder was blocked. Windows wants you to use a named account with a password instead of anonymous access.
How do I fix error code: 0x800704f8 on Windows 11?
If it appears for a shared folder, sign in with a real username and share the folder to that user. Clear old credentials and set the network to Private. If it appears elsewhere, update Windows and run SFC and DISM.
Is it safe to allow insecure guest logons?
Only on a small private network you fully control, and only temporarily. It removes a protection. Setting a username and password on the shared device is much safer.
Why do I get 0x800704f8 when signing in?
Windows uses the same code in several features, so the cause is general. Restart, install updates, check the system files and test with another user account to see if your profile is the problem.
Will a new user account fix it?
It helps when the old profile is damaged. It does not help when the block is a network sharing rule, because that rule sits on the other computer.
