Reporting Services And IIS Errors - Cannot Connect To Database Etc.

hi,

I set up Reporting Services about 9 months ago when I installed Microsoft CRM 3 (Dynamics?), but these problems have only just started occurring. Lost count of how many hours have been wasted looking for answers!

Apologies if this rambles on like a cheap book but i don't want to miss out any of the detail..


CRM stops working within an hour of IIS starting up, but if somebody logs in to CRM before it goes down then it's fine for the rest of the day. However the next day it's back to square one. Looking through Event logs it seems to be caused by SQL Reporting Server, because;

Report Server errors show it starting up after IIS, but within an hour throws up "Exception: System.Runtime.Serialization.SerializationException - Message: Unable to find assembly 'Microsoft.ReportingServices.Diagnostics". It's at this point that IIS stops responding altogether, hence CRM stops working.

Running iisreset from the command line makes IIS work again, but this becomes a pain in the backside running it every morning before my colleagues get in. I have set up a schedule to run it for me, which works, but as i said if nobody logs in within the hour (which does happen at least once a week), then CRM won't work until i manually run iisreset again.

Also Reporting Services Configuration Manager does not start properly, so i can't even go through that to see if it's a config problem - when launching it i get an alert box with "An unknown error has occurred in the WMI Provider. Error Code 800706B3". That's with the default server name already in the box, but no matter what server name or IP I try to get it to connect to, it just will not have it. Also that error code seems to be unique to me, since not one webpage exists with the same code.

Other things i've gone through;

- SQL Server Configuration Manager shows everything Running, including Report Server
- SQL Management Studio shows all CRM & Reporting Services databases exist and are online.

- The Report Server error log shows this: "w3wp!library!1!29/03/2008-12:34:00:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.ReportServerServiceUnavailableException: The Report Server Windows service 'ReportServer' is not running. The service must be running to use Report Server."

- http://localhost/ works fine.
- http://localhost/Reports/ shows up a .Net error page with Security Exception error: "The application attempted to perform an operation not allowed by the security policy".
- http://localhost/ReportServer/ shows up a page with "localhost/ReportServer - / ---- Microsoft SQL Server Reporting Services Version 8.00.1038.00" which i assume is lacking correct content.

- When CRM was configured the setup wizard moaned that it could not use the existing Reporting Services database or IIS directories, so for that purpose there are two more virtual directories in IIS..
- https://localhost/ReportsSQL/ shows up an error: "Unable to connect to the remote server"
- https://localhost/ReportServerSQL/ shows up an error: "Reporting Services Error - The Report Server Windows service 'ReportServer' is not running. The service must be running to use Report Server. (rsReportServerServiceUnavailable)"

- While trying everything i am logged in as server admin
- Software specs: Windows 2003 Small Business Server (SP2), SQL Server Standard 2005 (9.0.3054 / SP2), all patches from Microsoft Update (not just Windows Update) have been applied.


If you managed to read this far then thank you.. I'm nearly bald with frustration so if someone could please suggest things worth looking into or trying, that would be very much appreciated.

Cheers
