SYMPTOMS
The Microsoft Commercial Internet System (MCIS) 2.5 HTML Mail Interface (HMI) fails and returns ASP error messages. Internet Explorer clients that are running HMI WebMail return the following error message:

error 'ASP 0115'

Unexpected error

/email/Messages.asp

A trappable error occurred in an external object. The script cannot continue running.

The MCIS 2.5 HMI server logs the following events in the Application event log:

Asp 5 error; Unexpected error



CAUSE
The HMI COM object, Renobj.dll, attempts to allocate local heap for processing Web mail. In some cases, a large enough buffer is not allocated. This can result in an Access Violation error message if the subsequent heap header information is damaged.
