Error occurs when you debug a COM+ component in the Visual Basic IDE with an ASP client (259725)

RESOLUTION

Workaround 1

1. Create the entry for VB ASP Debugging in DCOM:
   1. Start Microsoft Notepad or another text editor and type the following case-sensitive syntax:

      REGEDIT4
      [HKEY_CLASSES_ROOT\CLSID\{70F214BA-94E2-4bdf-8F30-32CB4A905E4D}]
      @="VB ASP Debugging"
      [HKEY_CLASSES_ROOT\CLSID\{70F214BA-94E2-4bdf-8F30-32CB4A905E4D}\LocalServer32]
      @="vb6.exe"
      [HKEY_CLASSES_ROOT\AppID\vb6.exe]
      "AppId"="{70F214BA-94E2-4bdf-8F30-32CB4A905E4D}"

   2. Save the file as Vbaspdbg.reg.
   3. Locate the folder where you saved the Vbaspdbg.reg file and double-click the file (it automatically registers itself in the Windows registry).
2. Add the Everyone account to the DCOM permissions for Visual Basic ASP debugging.
   
   Windows 2000
   1. Start DCOMCNFG. On the Start menu, click Run, and then type dcomcnfg in the dialog box.
   2. On the Distributed COM Configuration Properties page, click the Applications tab, select VB ASP Debugging from the list, and then click Properties.
   3. In the VB ASP Debugging Properties property sheet, click the Securities tab, and then click to select the Use custom access permissions check box. Click Edit.
   4. In the Registry Value Permissions window, click Add, and then add the Everyone account for Allow Access.
   5. Click OK, and then click Apply to apply the changes and exit the Distributed COM Configuration properties page.
   6. Restart the computer so that the changes take effect.
   Windows XP
   
   
   1. Start COM+ Explorer. On the Start menu, click Admin Tools, and then click Component Services.
   2. Click to expand Component Services, click to expand Computers, click to expand My Computer, and then click to expand DCOM Config.
   3. Right-click VB ASP Debugging, and the click Properties.
   4. On the Securities tab, under Access Permissions, select Customize, and then click Edit.
   5. In the Access Permission window, click Add, and then add the Everyone account for Allow Access option.
   6. Click OK, click Apply, and then click OK to apply the changes and exit the DCOM Configuration properties page.
   7. Restart the computer so that the changes take effect.

Workaround 2

1. For debugging purposes, configure the Application Protection of Virtual Directory where the ASP page resides to "High (Isolated)." This forces the ASP page to run in its own process, which allows the security to be changed without affecting the rest of the Web site.
   1. Start Internet Services Manager.
   2. Right-click the Virtual Directory where the ASP page resides, and then click Properties.
   3. Click the Virtual Directory tab, and then select High (Isolated) in the Application Protection drop-down list.
   4. Click Apply.
2. Turn off Anonymous Access for this Virtual Directory and make sure Integrated Windows authentication or Basic authentication is selected:
   1. On the Properties dialog box for the Virtual Directory, click the Directory Security tab.
   2. Click Edit for Anonymous access and authentication control.
   3. Make sure that the Anonymous access check box is cleared.
   4. Click either Integrated Windows authentication or Basic authentication.
3. If Integrated Windows authentication is used, then run the client browser to access the ASP page under the same user account as the Visual Basic IDE debug session. If Basic authentication is used, enter the username and password for the same user account that the Visual Basic IDE debug session is running under.
   
   Note The second workaround assumes that the COM "Default Access Permissions" have not been altered. If the "Default Access Permissions" have never been altered, then COM constructs an access control list (ACL) that grants permission to the System account and Server Identity. In this scenario, the Server Identity is the user logged in running the Visual Basic IDE debug session. If the DCOM "Default Access Permissions" have been altered, then the second workaround requires that the user account that the Visual Basic IDE debug session is running under be added to "Default Access Permissions". This can be done by using DCOMCNFG. For additional information, see the "COM security" link in the "More Information" section.
