Category: General
Type: Error
Event ID: 4999
Watson report about to be sent to dw20.exe for process id: <Process ID>, with parameters: E12N, <Build Type>, <Version Number>, edgetransport.exe, exrpc32.dll, <XXXX>, c0000005, <XXXX>, <Version Number>. ErrorReportingEnabled: False


This issue occurs because Exrpc32.dll does not verify a NULL buffer before it accesses the buffer when the message is delivered. Therefore, an access violation occurs in the EdgeTransport.exe process.


To resolve this issue, install the following update rollup:
