What does Windows error code 7010 (ERROR_CTX_INVALID_MODEMNAME) mean?

ERROR_CTX_INVALID_MODEMNAME

The modem name was not found in MODEM.INF.

ERROR_CTX_INVALID_MODEMNAME is Win32 error 7010 (0x00001B62).

What to verify

Verify whether the configured modem name exactly matches an entry available to the Terminal Services callback component. Check configured modem name, enumerated modem devices and driver versions, and MODEM.INF entries.

Likely causes

• the modem was renamed or removed.
• configuration refers to a model not present in MODEM.INF.
• driver migration changed the friendly name.
• configuration was copied from another server.

Troubleshooting steps

1. Collect configured modem name.
2. Record enumerated modem devices and driver versions.
3. Correlate MODEM.INF entries with TerminalServices operational logs, session and user-configuration records, device or modem diagnostics, and the caller’s connection trace.

Handling, retry, and recovery

Select an installed modem entry or remove legacy callback configuration, then test with the same user policy.

Example

A callback profile names a modem from an older server image. Enumerating installed modems shows a different model name, and updating the profile allows initialization.
