Today I had an issue with workflows on our CRM server, specifically that none of them would run, so in order to resolve the issue I looked at the trace log and found that we were receiving the following error…
Looking at the CRM Asynchronous Service, I could see that it was running under the correct domain account (CRM Admin), however I discovered that this account needs to belong to a specific group in AD also (PrivUserGroup), so I then performed the following steps…
1. Open Active Directory and Computers (dsa.msc)
2. Find your PrivUserGroup
3. Open group and add your domain account running your CRM services
4. Run iisreset on CRM server.
5. Restart CRM Asynchronous Service.
And hey presto, workflows can then be ran on the server.

To put a total at the end of the SSRS report, add a textbox to the DataSet Region and set the visibility property of the text-box to an expression - set the the expression to:
Then a just set the expression on the text box to:
and this is what it looks like rendered:
Enjoy!

On deploying a site for a customer we were presented with all sorts of ASP.Net errors. First I was told that the database was the incorrect type (i.e. the app thought it was SQL Express edition instead of the SQL Standard Edition).

To resolve the issue I started looking at my database; you’d think that was the obvious place or not? I restored my database, that didnt work, I attached my MDF files, that didnt work, finally I even tried to build the database entirely using SQL Scripts; but still the app was telling me that the database was a SQL Express Schema.
In desperation, I searched my code for any references to .MDF which I may have had…nothing; I searched for connection strings - no luck there either! What was going on?
Eventually - for no reason other than to try attaching the .MDF file again; I did a file search on my dev machine and found that there was an ASPNET.MDF file present in the app_data folder. Now, this shouldn’t be there, I was using my own database for roles based authentication. So I deleted it. Redeployed my site; and again was told there was no database…
I gave up on the host; clearly they were going to be no help so I set about replicating the environment on our own servers. I set up the site; configured role memberships and disabled custom errors…on browsing the site; I was able to find out that the ASPNET user was trying to create a database in the App_Data folder; I have no idea why; so yet again I searched through all my source for any reference to App_Data that was there. Nothing. Absolutely no references. So I deleted the Folder.
As soon as I hit CTRL-F5 the site worked…could this have been the error? All my problems seemed to have been caused by the ASPNET worker process trying to create a database in the App_Data folder even though it was never used.
I have yet to fathom out why ASP.Net decides to create a database in the APP_Data folder; but if its causing you problems you simply need to delete the folder (as long as you arent using it).
