SBS2011 DCOM error

Posted on 2013-06-18

We keep getting the following DCOM error on our single sbs2011 server, as follows :-

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID
 and APPID
 to the user DOLPHIN\sbsadmin SID (S-1-5-21-4227830585-1524740534-106091535-1156) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.

I have been advised to :-

1. Click Start -> Run -> Type -> dcomcnfg, expand Component Services -> Computers -> My Computer -> DCOM Config.
 2. Click View -> Detail -> Now you will get Application Name and Application ID in right side.
 3. Scroll down and find the application ID {AD65A69D-3831-40D7-9629-9B0B50A93843} -> Right Click -> Properties and select the Security tab.
 3. Click Customize under "Launch & Activation Permission" -> click Edit -> Add in the account NT AUTHORITY\SYSTEM and set local launch and local activation.
 4. Restart the application Service linked to this Application ID or restart the server and monitor

But when we get to edit the "Launch and Activation Permission" all of the options are greyed out, so we cannot change them.

Can anyone provide any assistance please?

Many thanks.

Please try with Run as administrator and make sure you allow DOLPHIN\sbsadmin as well into local launch permission.

I right clicked on Component services and selected "run as administrator", but unfortunately, all of the edit options are still greyed out.

Any ideas?

By Design, on windows 2008, it won't allow you to modify DCOM.

I would suggest you to refer following article which will give you idea on how to....

I have checked out the link provided, and unfortunately the first instruction has me baffled! :)

1. Run Regedit.exe and browse to "HKEY_CLASSES_ROOT\AppID\{61738644-F196-11D0-9953-00C04FD919C1}" key.

Can find the HKEY_CLASSES_ROOT but not AppID?

Where do I go from here??

Many thanks.

In your original post, The appid is referenced in the error log, ie 'D3DCB472-' etc.

This is what you need to find under Hkey_classes-root.

So replace AppID with the reference detailed previously. Will take a look.

Many thanks.
