PDQ Deploy and\or PDQ Inventory report "Kerberos: The target account name is incorrect" when scanning or deploying to a computer.
Troubleshooting steps
The Windows and Kerberos native error "KRB_AP_ERR_MODIFIED" indicates that the PDQ software connected to the computer through Kerberos, but its computer verification process failed. On the PDQ server, Windows logs these errors in the System event viewer log with event ID 4 and source Security-Kerberos. You can review this log to see which computer the software attempted to connect to.
This error is typically caused by a misconfigured DNS environment. Possible issues include stale DNS entries or multiple DNS records with the same IP address. PDQ software uses SMB to connect to computers. SMB relies on Kerberos or NTLM authentication, which in turn depends on DNS.
