Virtual Server 2005 and XPSP2 RC2

Posted in Sql and Xml | General at Thursday, July 01, 2004 3:26 AM Pacific Daylight Time

Well with all the new express products just waiting to be tried I figured I would fire up my Virtual Server 2005 and create some new instances of Windows XP to test them out. However, whenever I tried to get into the Virtual Server 2005 administration website I would get an access denied error. Hmmm...

My first guess was to assume it was the firewall blocking my access. However turning off the firewall had no effect.

My next step was to take a look at the event viewer and there I found the first clue as to what the problem was. There was a bunch of error logs with the message:

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID

{DA3111BC-1BD7-4884-A535-8470D36028F7}

to the user [snip]. This security permission can be modified using the Component Services administrative tool.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Ok. Next I opened the Component Services admin tool and looked under the DCOM config. There were quite a few entries there so instead of looking for the component by the GUID I did a quick registry search for the GUID and found the human readable name is “Virtual Server“. :)

Scrolling down in the Component Services admin tool I found the Virtual Server entry, right clicked it, selected Properties, switched to the security tab, edited the Launch and Activation permissions, changed local activation properties to “Allow“, and now everything works!

So, the problem was with XPSP2 which makes COM more secure. Hopefully this will be fixed in the next RC of Virtual Server 2005 so that this blog entry doesn't become a popular topic.

Now, on to my real goal which was to start playing with SQL Server 2005 Express...

Just to let you know, this problem still hasn't been resolved in the release versions of the VS 2005 and XP SP2. I figured out what was wrong and then searched to see if there was a known solution posted, this was the only real reference i found.

<br>
<br>I get this error in my event viewer everything i start to view my localhost.
<br>
<br>"The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {0C0A3666-30C9-11D0-8F20-00805F2CD064}"

This problem also exists with Virtual Server on Win 2003.

I still get this error
The service principal names for Virtual Server could not be registered. Constrained delegation cannot be used until the SPNs have been registered manually.

Do you have some solution?

Hi,

the same problem still exists on Vista x64. BUT even after setting the appropiate permissions (as suggested by KB article) it DOES NOT work.
Any suggestions?
