SYMPTOMS

Error ASP 0178 occurs when using the MEMail.Message component from web pages.

CAUSE

RESOLUTION

Ensure that the IIS proxy account has permissions to instantiate/access the appropriate COM libraries. This can be done using the Windows Explorer by granting the IUSR_[Machine] account access to the file MEASP.dll in the C:\Program Files\Mail Enable\BIN directory.

To do this from the Windows command prompt the following should work:

C:\>CACLS "C:\Program Files\Mail Enable\BIN\MEASP.DLL" /e /g IUSR_[Machine]:R

Note: Substitute [Machine] with the name of your computer. Please check for the existence of this account under Administrative Tools|Computer Management.

If still experiencing problems, it is possible that an account other than the IUSR_[Machine] account is being used as the IIS proxy account. Please follow the instructions outlined below:

1. Open the Internet Service Manager and navigate to the asp file that contains the code.
2. Select the "File Security" tab
3. Under "Anonymous access and authentication control", select the Edit button
4. Take note of the username that is used for anonymous access to this account.
5. Close all windows within the Internet Service Manger
6. From the Windows Start menu, search for any files named MEASP.DLL on the system (there should only be one; and it should be in the MailEnable BIN directory).
6. Right click on the file(s) and access Properties.
7. Ensure that the username (from step 4) has (Read) and (Read & Execute) permissions granted to access this file.
8. Re-test the application
