Microsoft Dynamics CRM 2011 Error: Sandbox Host - Access Denied.

Have you guys got this error in Event Viewer of Microsoft Dynamics CRM server anytime while accessing Microsoft Dynamics CRM or while performing operations on DCRM?

I recently got this error when I was trying to perform some operation and could not able to complete that operation. That was because the user I was logged into DCRM didn't have logon permission in the Local Security Policy.

Here are the steps which you have to follow to resolve the issue.

• In "Local Security Policies" added your DCRM user () under "Log-on as service".
• From elevated command prompt execute following command: "SETSPN -a MSCRMSandboxService/ \" (the required SPN was not present earlier)
• Reset CRMAppPool Application pool to restart the DCRM web-services.
• Changed the "Log On As" for "Microsoft Dynamic CRM Sandbox Processing Service" to “\”  (It should not be "Network Service". I guess by default it is Network Service).
• Re-start the service
• Add  in web.config of CRM Web Site.. this is to get more details about the problem if this is still continuing.

I am not sure if you guys have ever experienced or currently experiencing problem downloading large files from SharePoint. Recently I faced same problem and found one simple solution to this problem.

Please follow simple steps on your computer to resolve this issue.

1. Open a Command prompt window as Administrator on a computer where you are trying to download large files from SharePoint.

2. Type and run following command.

netsh int tcp set global autotuninglevel=disable

3. Now try the downloading same large file again. Now you should be able to download/open file successfully.

Q. How to run Command prompt always as Administrator in Windows?

Recently while working on one of the assignment on Windows server, I used to run command prompt always as Administrator. Every time I was following same old steps (i.e. Right click on command prompt short cut, then select "Run as Administrator" option). I didn't like it and then decided to find better option.

I tried couple of options and found one solution. Using it now whenever I run command prompt on my server it always runs as Administrator.

There might be many other options or solution to solve this problem but I found this one very simple and effective.

Steps to run Command Prompt always as Administrator are as follow:

1. Right click on the Command prompt shortcut and select "Properties" from the menu.












2. Go to "Shortcut Tab and click on "Advanced..." button
