Error 0x801C03EA: TPM Version Mismatch

Error Message

Registering your device for mobile management (Failed: 3, 0x801C03EA).

Error Details​

PropertyValue
Error Code (Hex)0x801C03EA
Error Code (Dec)-2146434070
Failure Code3

Description​

info

This error occurs when attempting to register a device that has a TPM (Trusted Platform Module) chip capable of version 2.0 but is currently running an older version. The error can also appear when there are conflicting Autopilot profile assignments for the same device.

Common Causes​

🔐 TPM Version Issues​

Registration failures often stem from TPM version mismatches. TPM chip supports 2.0 but runs older version. Version upgrade not completed. TPM configuration requires update. Understanding TPM requirements is crucial for successful registration.

📋 Profile Assignment Conflicts​

Configuration complications can prevent successful registration. Device might be in multiple assigned groups. Conflicting Autopilot profiles could be assigned. Profile assignments need resolution. These assignment factors require systematic verification and correction.

Resolution Steps​

1️⃣ Option A: Upgrade TPM​

Update TPM to version 2.0:

  1. Verify TPM capability
  2. Access BIOS/UEFI settings
  3. Locate TPM configuration
  4. Upgrade to version 2.0
  5. Save and restart

2️⃣ Option B: Resolve Profile Conflicts​

Check Autopilot profile assignments:

  1. Review device group memberships
  2. Identify conflicting profiles
  3. Determine correct profile
  4. Remove incorrect assignments
  5. Verify single profile assignment

3️⃣ Verification​

After implementing changes:

  1. Restart device
  2. Verify TPM version
  3. Check profile assignment
  4. Attempt registration again

Best Practices​

👨‍💻 For IT Administrators​

Effective device management requires attention to TPM configuration. Implement comprehensive version monitoring. Maintain documentation of TPM requirements. Develop clear procedures for version upgrades. Create systematic approaches to profile management. Consider implementing automated assignment verification.

🔄 For Profile Management​

Successful registration requires proper profile configuration. Develop clear processes for assignment management. Maintain accurate documentation of group memberships. Implement thorough testing procedures for profiles. Create comprehensive documentation of assignment steps.

Troubleshooting Tips​

Configuration Management

When addressing registration issues, focus on both TPM and profile verification. Check TPM version carefully. Verify profile assignments. Test registration after changes. Monitor for successful completion.

Important Considerations

Configuration management involves several factors. TPM upgrades need planning. Profile conflicts require resolution. Consider device restart requirements. Monitor registration success.
