How can I fix "DllRegisterServer entry point was not found" errors on Windows 7?

When I execute regsvr32 inetcomm.dll from Start > Run, I get the following error:

Any suggestions? I am using Windows 7.

EDIT:

I am using Outlook 2007 and have configured my mail... it only works sometimes. I can receive mails without any problems but sending is the issue: when my sending fails it says:

Sending reported error "0x800ccc60"

When I searched for my Outlook failure one of the articles said I should run the following line: regsvr32.exe inetcomm.dll.

Outlook 2007 works pretty well for me in XP but not in Windows 7. Any ideas why this might be? I think it is because of inetcomm.dll... see the link below which demonstrates my problem:

The answer is in your screen capture:

I went to the URL. I got this message:

If you wish to request a delisting please do so through the Support System.

What this says to me is that your SMTP server is a known vulnerable server. Outlook is protecting you.

Instead of trying to reinstall Outlook, you should consider using a separate SMTP server before jumping to conclusions. Seriously.

I hope this helps.

inetcomm.dll doesn't export a DLLRegisterServer function.

Have you tried preventing regsvr32 from calling DLLRegisterServer by using the /n and /i parameters?

regsvr32 /n /i inetcomm.dll
