An unknown error has occurred.

Windows Live Mail Error ID: 0x800C0148

Protocol: SMTP

Port: 0

Secure (SSL): No

And sometimes, the error dialog just pop up without stating specific error!

===== Solution =====

[1] The {Port: 0} error in Windows Live Mail usually relates to anti-virus application, and thus, I tried to disable the email scanning feature of my anti-virus application… but, this cannot resolve the problem.

[2] I suspect that some of the registered interfaces of the DLL files are corrupted. I used REGSVR32 to register them again, and this seems to have resolved the problem. I do not know exactly which DLL is required this time, while here comes my list of REGSVR32 *.DLL…

regsvr32 actxprxy.dll
regsvr32 oleaut32.dll
regsvr32 urlmon.dll
regsvr32 jscript.dll
regsvr32 vbscript.dll
