Frequently Asked Questions

What causes error 0xC0000080 in Windows?
This error is caused by the Remote Procedure Call (RPC) service being disabled, stopped, or blocked by firewall or network issues. Corrupted system files or conflicting software can also trigger it.
Can a virus cause error 0xC0000080?
Yes, malware can disable the RPC service or corrupt system files to cause this error. Run a full antivirus scan if you suspect infection.
Do I need to reinstall Windows to fix error 0xC0000080?
Reinstalling Windows is rarely the first step. Most cases are resolved by restarting services or running system file checks. Only consider reinstall if all other troubleshooting fails.
How do I restart the RPC service if it won't start?
If the RPC service won't start, check its dependencies (Remote Procedure Call (RPC) Locator, DCOM Server Process Launcher). Ensure those are running. Also verify the service account is set to 'NT AUTHORITY\NetworkService'.
Can a firewall cause this error?
Yes, if Windows Firewall or a third-party firewall blocks ports used by RPC (TCP 135, 139, 445, and dynamic ports). Temporarily disable the firewall to test. If the error resolves, add exceptions for RPC.
