SYMPTOMS
========
When debugging a WebClass from the Visual Basic IDE, the following error
occurs:
Server object error 'ASP 0178 : 800a0005'
Server.CreateObject Access Error
/Temp/WebClass1.ASP, line 14
The call to Server.CreateObject failed while checking permissions.
Access is denied to this object.
You might also notice a Transaction Server Error entry in the NT Application
Event Log. The details of the error message should look similar to this:
Failed on creation from object context: IClassFactory::CreateInstance
(ProgId: Project1.WebClass1) (CLSID: {C2B16A1D-3C8F-11D2-8015-
00C04FB9D877}) (Interface: IUnknown) (IID: {00000000-0000-0000-C000-
000000000046}) (Microsoft Transaction Server Internals Information: File:
d:\viper\src\runtime\context\ccontext.cpp, Line: 1220)
RESOLUTION
==========
You need to give the IUSR_<machine_name> account permissions to launch and
access your project using dcomcnfg by doing the following:
1. Launch DCOMCNFG by clicking the Start button, selecting Run, and typing
"Dcomcnfg.exe" (without the quotation marks) in the Run dialog box.
2. In the Default Security tab, click Edit Default in the Default Access
Permissions frame. The Registry Value Permissions dialog box appears.
3. Add the IUSR_<machine_name> account and the INTERACTIVE account to the
Registry Value Permissions dialog box and click OK.
4. In the Default Security tab, click Edit Default in the Default Launch
Permissions frame. The Registry Value Permissions dialog box appears.
5. Add the IUSR_<machine_name> account to the Registry Value Permissions
dialog box and click OK.
