After installing the c360 Toolkit on our CRM server the following two messages are logged to the Application Event Log quite often. The SDK itself seems to work (we are using the Grid Control primarily). There are no Exceptions visible to the user, however we have some performance issues and unexpected terminations of the app pool used for the c360 SDK. (See message at the end of the post)
The error occurs every 1 to 5 minutes, shortly followed by the warning.

Server is Windows Server 2003, The App Pool uses the Network Service account and runs under .NET 2.0.

Is this a known problem?
Any ideas how to solve this.

Thanks in advance.

This problem indicates that our SDK is trying to connect to a web service but the URL is incorrect and the expected web service is not present at the configured address. I also notice the following information in the error's stack trace:

This tells me that this error occurs when we try to retrieve the list of SRS reports that are configured for an entity. Our SDK is designed to gracefully handle this kind of problem by simply removing the "reports" button instead of displaying an error message to the user. This issue can be easilly fixed by correcting the configured URL for your reporting server. The key that need to me modified is documented in the training guide in the "Post-Installation Configuration" section.

thanks for your help so far.

I have now changed the report parameter url in the config file and changed the app pool to use a local administrator account.

We now get the errors listed below. There still seem to be problems with the event source.

I actually don't want to use the administrator account on our production system. What are the recommendations for the app pool identity to ensure that all permissions are available?

Regards
Philipp

The recommended way to configure your AppPool is to accept the default identity and not change it to a given usr. If I remember correctly, the default identity is "network service".

The root of this problem seems to be:

However, this is really difficult for me to investigate without looking at your code. Can you post your code so that I can attempt to reproduce the problem?

We could resolve the problem by explicitely removing the reports button from the grid. The problem seems to occur when the grid is based on a custom entity which does not have any reports.

However, I would still like to resolve the problem that every error which is logged to the event log produces two additional error message because there is no registry access for the Network Service account.

As it seems to be recommended to run the c360 toolkit application pool with the Network Service account I'd like to add the necessary permissions to the registry to make that work without problems.

Any recommendations?

Thanks!

Philipp

Ok, this is the information I needed. I was able to reproduce the problem: there is indeed a problem when you are displaying an entity with not SRS reports defined. Our code loops through an array of reports to list them on the grid's menu bar but this code fails when the array is empty. However, keep in mind that the only side effect of this problem is an annoying entry in the event log. The user does not see any error.

I have reported this issue as defect DE1654.

Have you tried recreating this situation with a local admin account (assuming that local admins have the permission to write to the registry)? Another suggestion would be to use a tool like RegMon to detect which account is trying to write to the event log, which branch it's trying to write to and therefore grant this account the appropriate permission.

I have never experienced this problem myself but you are at least the second customer to complain about this issue so I wonder what can be different in your case. Maybe you are using Small Business Server where the security restrictions are different? Maybe you have applied a domain policy that restricts registry access?

I have similar problem, so I thought I just kidnap this thread for myself.

I also get application errors, followed by warnings in Event Log. It points a language *.xml file as a source (at least that's what I think it's saying). The number of error-warning pairs varies from 1 to 4 depending on which language file I'm using.

Here's what the entry in Event Log says:
