Identifying the Problem

Error Code 1727 is an RPC (Remote Procedure Call) error that occurs when a call to a remote procedure on a different computer fails. It typically arises due to network issues or firewall interference. Signs of this error include difficulty connecting to remote resources, accessing shared folders, or using remote services.

Common Fixes

  1. Check Network Connectivity: Verify that your computer can establish proper network connections. Disable and then re-enable your network adapter if necessary.

  2. Adjust Firewall Settings: Ensure that your firewall is configured to allow RPC traffic. Check both inbound and outbound rules to ensure that RPC-related ports are not blocked.

  3. Restart RPC Service: Open “Services” (services.msc), locate “Remote Procedure Call (RPC)”, and restart it. This action can rectify any service-related issues.

  4. Re-register RPC Files: Open a Command Prompt as an administrator and run the following commands:

    • regsvr32 ole32.dll
    • regsvr32 rpcrt4.dll
    • regsvr32 rpcsrv.dll

  5. Update Network Drivers: Outdated or corrupt network drivers can lead to connectivity issues. Navigate to “Device Manager” and update your network adapter drivers.

Advanced Troubleshooting

  1. Disable IPv6: Temporarily disable IPv6 on both the problematic computer and the remote server. IPv6 conflicts can occasionally trigger Error Code 1727.

  2. Check DNS Settings: Ensure that your DNS settings are configured correctly. In “Network Connections”, select your network adapter, click “Properties”, and set your DNS servers to obtain them automatically or use known public DNS servers like Google’s (8.8.8.8) or Cloudflare’s (1.1.1.1).

  3. Use Remote Procedure Call Tester: Utilize the Remote Procedure Call Tester tool (rpctest.exe) to diagnose RPC issues more thoroughly. Run the tool and check the results for any potential problems.
