faulting module ntdll.dll

[Raj]

Hi All,
I am using mailto.exe for alerting from batch files for
various administration tasks. I get this error in the event log.

Reporting queued error: faulting application MAILTO.EXE, version
0.0.0.0, faulting module ntdll.dll, version 5.2.3790.1830, fault
address 0x000210c8.

However mailto.exe works perfectly I am just worried about ntdll.dll
error in the application log.
Has anybody experienced this, please let me know.

Thanks
Raj
