Hello,
The c# web app works fine in windows XP, and in Debug mode inside the server with Visual Studio. But, when I deploy this in Windows Server 2008, IIS 7, I have an:
Creating an instance of the COM component with CLSID {850D1D11-70F3-4BE5-9A11-77AA6B2BB201} from the IClassFactory failed due to the following error: 80070005
I tried to solved this error doing:
a) The WIA service is not installed during the default Windows Server 2008 installation. Before you can enable WIA, it first needs to be installed:
- Click the Start button, open the Administrative Tools menu, and click Server Manager.
- Click Features to load the Features Summary, then click Add features.
- Check the Desktop Experience check box.
- Click Next, then click Install.
- Restart your computer.
Now you can enable WIA as follows:
- Click the Start button, open the Administrative Tools submenu, and clickComponent Services.
- In the Component Services dialog, click Services (Local) to load the list of services.
- Locate and right-click "Windows Image Acquisition", then click Properties.
- In the General tab, set the Startup type to "Automatic".
- Click OK.
- Right click "Windows Image Acquisition" again, then click Start.
b) Giving access in windows\System32\wiaaut.dll to:
- IUSR
- Network Service
- IIS_USRS
c)Local Security Policies
1. Start -> Control Panel -> Administrative Tools -> Local Security Policy
2. Navigate to Security\Local Policies\Security Options
a. Network Access: Let everyone permissions apply to anonymous users - Set to Enabled
c. DCOM: Machine Access Restrictions - Add Anonymous, Everyone, Interactive, Network, System with full rights options set.
d. Network Access: Let everyone permissions apply to anonymous users - Set to Enabled
e. Network Access: Sharing security model for local accounts - Set to Classic
The "Sharing Security model" is the real offending item I believe, and setting the above should fix the problem. If not then I went as far as setting the following in DCOMCNFG.
DCOM Configuration
1. Click Start -> Run
2. Enter DCOMCNFG and press OK. This will open the DCOMCNFG window.
3. Browse down the tree to Console Root -> Component Services -> Computers -> My Computer
4. Right click on "My Computer" and select properties
5. Select the "Default Properties" tab
a. Enable Distributed COM on this computer - Option is checked
b. Default Authentication Level - Set to Connect
c. Default Impersonation Level - Set to Identify
6. Select the "COM Security" tab
7. Click on Access Permissions ' Edit Default
a. Add "Anonymous", "Everyone", "Interactive", "Network", "System" with Local and Remote access permissions set.
8. Click on Launch and Activation Permissions ' Edit Default
a. Add "Anonymous", "Everyone", "Interactive", "Network", "System" with Local and Remote access permissions set.
9. Click on OK
10. Close the DCOMCNFG window
d) In windows\system32>regsvr32 wiaaut.dll (running as Administrator the command prompt)
But I'm still having this error!!!
Could you please help me?
Thanks in advance!!!
