We have just installed the HR2 hotfix rollup onto our Tridion Content Manager servers. These servers were previously running SDL Tridion 2011 SP1 HR1.
We have upgraded the CM database and completed the installation on the CM servers. Now when I try and access the CM Explorer in a browser, I see the following error. The CM Explorer doesn't load the list of publications, and throws the following error:
The remote server returned an error: (404) Not Found. at System.Net.HttpWebRequest.GetResponse() at System.ServiceModel.Channels.HttpChannelFactory.HttpRequestChannel.HttpChannelRequest.WaitForReply(TimeSpan timeout)
We are also seeing the following error in the event logs on the CM Servers:
A method call to an object in a COM+ application was rejected because the caller is not properly authorized to make this call. The COM+ application is configured to use Application and Component level access checks, and enforcement of these checks is currently enabled. The remainder of this message provides information about the component method that the caller attempted to invoke and the identity of the caller.Svc/Lvl/Imp = 10/6/1, Identity = <Username>
Does anyone have any ideas what could be causing this? Has the installer reset some of the DCOM configuration settings, or bindings, or has something not been restarted correctly?
Both CM servers have been rebooted following the installation.
