Arkadaşlar ben sorunun çözümü tam olarak bu şekilde gerçekleştirebildim.

To fix this issue, perform the following steps:

* From the SBS console, click Administrative Tools > Component Services
(or, if you prefer: click Run > comexp.msc)
* Expand down Component Services > Computers > My Computer > DCOM Config
* Right click on IIS WAMREG Admin Service, then click Properties
* Click on the Security tab
* Click the Edit... button within the Launch and Activation Permissions section
* Click Add and add the user named: 'Network Service'
(NB: this is the step that confuses people. Most instructions simply tell you to add the appropriate user, but do not make it clear which user to add!)
* Click on the checkbox to Allow (enable) the Local Activation rights option for this user
* Click OK twice, and close Component Services
* Finally reboot the server for good measure and to ensure the change takes effect
