Failed To Start | Service Veeamdeploysvc [patched]

Troubleshooting Guide — “Failed to start service veeamdeploysvc”

This guide provides a concise, step-by-step approach to identify and fix the “Failed to start service veeamdeploysvc” error (Veeam Deployment Service). Assume Windows Server environment and Veeam Backup & Replication. Proceed in order; check the note at the end for logs and escalation.

Scenario A: Port Conflict (TCP 6160)

The VeeamDeploySvc listens on TCP port 6160 by default. If another application or a zombie process binds to this port, the service will fail to initialize.

Solution 6: Use Veeam Cleaner Tool

Veeam provides an unofficial but widely used cleanup utility to remove all traces of a failed installation.

  1. Stop all Veeam services manually.
  2. Download the Veeam Backup Cleaner tool from Veeam’s KB repository (e.g., KB2787).
  3. Run the tool as Administrator and follow the prompts to remove registry keys, services, and files.
  4. Reboot and reinstall Veeam from scratch.

5. Check for Port Conflicts (Port 9392)

Open a command prompt as administrator and run: failed to start service veeamdeploysvc

netstat -ano | findstr :9392

If you see a LISTENING state with a different process ID (not Veeam), identify that process:

tasklist /fi "PID eq [ProcessID]"

If another application is using the port, either stop that application or change Veeam’s deployment port in the Veeam Console (under Backup Infrastructure → Managed Servers → Properties).

Pre-Troubleshooting Checklist

Before applying any fixes, perform these quick checks: Detection: Attempt to bind a test socket to port 6160

  1. Restart the server – Sometimes stale handles or temporary locks are released after a reboot.
  2. Log in with local administrator rights – Domain admins may have restricted local permissions.
  3. Check free disk space – Services need at least a few hundred MB to write temporary logs.
  4. Review Event Viewer – Navigate to Windows Logs > System and look for errors from Service Control Manager around the time of failure.
  5. Temporarily disable antivirus – Only do this on a protected network and re-enable it immediately after testing.

Step-by-Step Troubleshooting

Follow these steps in order. Most solutions take less than 5 minutes.

Advanced: Enable Debug Logging

If the error persists, enable verbose logging to pinpoint the exact failure.

On the Veeam Backup Server:

  1. Open Registry Editor.
  2. Navigate to HKLM\SOFTWARE\Veeam\Veeam Backup and Replication
  3. Create a new DWORD: DeployLogLevel with value 4
  4. Rerun the deployment job.
  5. Find the detailed log at:
    C:\ProgramData\Veeam\Backup\DeploymentLogs\

The log will show whether the failure is permission-based (access denied), file copy-related, or service start timeout.

Conclusion

The error "Failed to start service VeeamDeploySvc" is a hard stop, but it is rarely catastrophic. In 90% of cases, the culprit is a rogue process hogging port 9392 or a misconfigured service logon account switched to a domain user without proper privileges. By methodically checking port bindings, service account permissions, SQL connectivity, and antivirus interference, you can typically resolve the issue within 15 minutes.

If you have followed all seven troubleshooting steps and the service still fails to start, check the Windows System Event Log for a specific exit code (e.g., 1075, 1053, or 0xc000007b). Those codes point to deeper dependency issues, often requiring a full OS repair or contacting Veeam Support with a systeminfo export. Solution 6: Use Veeam Cleaner Tool Veeam provides

Remember: The Deploy Service is the delivery arm of your backup infrastructure. Without it, your backups can’t grow, and your agents can’t be updated. Keep it running, and your uptime will thank you.
