The information in this article applies to:

SYMPTOMS

When you run a WebClass (Internet Information Server [IIS] application) from the Visual Basic Integrated Development Environment (IDE) in Windows 2000, the following error message appears:
Could not start Internet Explorer
After you click OK, Internet Explorer does not open.

CAUSE

This behavior occurs only if the "IUSR_<machinename>" account has been added to the Default Access Permissions in the DCOM security settings. If you add only the IUSR_<machinename> account, this restricts the default access permissions for all DCOM servers that use the default permissions.

RESOLUTION

To resolve this problem, remove the IUSR_<machinename> account from the DCOM Default Access Permissions and follow the instructions in the following Microsoft Knowledge Base article:

MORE INFORMATION

Steps to Reproduce Behavior

On a fresh installation of Windows 2000 (not upgraded from Windows NT4.0), add IUSR_<machinename> to the Default Access Permissions in DCOM:
  1. Start DCOMCNFG: Click Start, click Run, and then type dcomcnfg in the Run dialog box.
  2. On the Default Security tab, click Edit Default in the Default Access Permissions frame. The Registry Value Permissions dialog box appears.
  3. Add the IUSR_<computername> account to the Registry Value Permissions dialog box, and then click OK.
  4. Apply the changes and exit the DCOM permissions window.
Create a new IIS Application in Visual Basic, and then click the Start button or press F5 to run the WebClass.
