How to manually remove the Microsoft Dynamics CRM 4.0 server

Typically, you can use Add or Remove Programs in Control Panel to remove the Microsoft Dynamics CRM server. You can also run the Microsoft Dynamics CRM server installation program to remove the Microsoft Dynamics CRM server.

Note You can run the ServerSetup.exe file to run the Microsoft Dynamics CRM server installation program.

However, if a problem occurs when you use one of these methods to remove the Microsoft Dynamics CRM server, you must manually remove the Microsoft Dynamics CRM server.

Note The Microsoft Dynamics CRM server contains many components. These components are related to many applications and to many technologies. For example, the components are related to Windows Server, to Internet Information Services (IIS), to Microsoft SQL Server, to SQL Server Reporting Services (SSRS), and to the Microsoft .NET Framework. Therefore, if you must completely remove the Microsoft Dynamics CRM server, consider completely rebuilding the computer instead of manually removing the Microsoft Dynamics CRM server.

To manually remove the Microsoft Dynamics CRM server, follow these steps.



Note The following steps describe how to remove the applications that are installed in a Full Server configuration. You can use similar steps to remove specific server roles. Additionally, the following steps do not remove all the components that are installed when you install the Microsoft Dynamics CRM server. However, after you follow these steps, you can reinstall the Microsoft Dynamics CRM server.

Step 1: Stop the Microsoft Dynamics CRM Asynchronous Processing service

1. Click Start, point to All Programs, point to Administrative Tools, and then click Services.
   
2. Right-click Microsoft Dynamics CRM Asynchronous Processing Service, and then click Stop.

Step 2: Stop the Indexing service

1. Click Start, point to All Programs, point to Administrative Tools, and then click Services.
   
2. Right-click Indexing Service, and then click Stop.
   

Step 3: Configure the Web site and the application pool

1. Log on to the computer that is running Internet Information Services (IIS). This computer has the Microsoft Dynamics CRM 4.0 Web site installed.
   
2. Click Start, point to All Programs, point to Administrative Tools, and then click Internet Information Services (IIS) Manager.
   
3. Expand the computer name, and then expand Web Sites.
   
4. Right-click the Microsoft Dynamics CRM 4.0 Web site, click Stop, and then click Yes.
   
   
   Note By default, the name of the Microsoft Dynamics CRM 4.0 Web site is Microsoft Dynamics CRM.
   
5. Right-click the Microsoft Dynamics CRM 4.0 Web site, and then click Properties. Click the Home Directory tab, click DefaultAppPool in the Application pool list, and then click Remove.
   
6. Click the ISAPI Filters tab, click CRM.Default.Addon isapi, and then click Remove.
   
7. Click OK.
   
8. Expand Application Pools, right-click the Microsoft Dynamics CRM 4.0 application pool, click Delete, and then click Yes.
   
   
   Note By default, the name of the application pool is CRMAppPool.
   
9. Close IIS Manager.
   

Step 4: Delete the Microsoft Dynamics CRM program files and the Microsoft Dynamics CRM folders

To do this, delete the following folder:
Notes

• If the Microsoft Dynamics CRM 4.0 server installation program created the Web site, the Web site is located in the following folder:
  
  Drive:\Program Files\Microsoft Dynamics CRM
  If you delete this folder, you also delete the Microsoft Dynamics CRM 4.0 Web site. Therefore, if you delete this folder, you have to create a new Microsoft Dynamics CRM Web site when you reinstall the Microsoft Dynamics CRM server. You can also re-create the default folder for the Web site.
  
• If you install the Microsoft Dynamics CRM Web site on the default Web site, the Microsoft Dynamics CRM Web site is in the following folder:
  Drive:\Inetpub\wwwroot
  Therefore, you have to delete all the files and all the folders except the Aspnet_client folder in the Drive:\Inetpub\wwwroot folder.

Step 5: Delete the Active Directory security groups

1. Log on to a domain controller as a user who has rights to delete the security groups.
   
2. Click Start, point to All Programs, point to Administrative Tools, and then click Active Directory Users and Computers.
   
3. Expand the domain node.
   
4. Expand the node of the organizational unit (OU) on which you install the Microsoft Dynamics CRM 4.0 server.
   
5. Delete the following security groups:
   
   • PrivReportingGroup
     
   • PrivUserGroup
     
   • ReportingGroup
     
   • SQLAccessGroup
     
   • UserGroup
   To delete a security group, right-click the security group that you want to delete, and then click Delete.
   
   

Note If there is more than one deployment of Microsoft Dynamics CRM 4.0 in the domain, you may have many security groups. To find the correct security group, follow these steps:

1. Open SQL Server Management Studio, and then click New Query.
   
2. Run the following statement against the MSCRM_Config database.

   select Id, DatabaseName, FriendlyName from Organization

3. Note the ID of the first organization. The ID is used in the name of the security group.
   
4. Find the security group in the Active Directory directory service. The name of the security group for the deployment contains the ID that you noted in step c earlier in this section.
   

Step 6: Remove the SQL Server logins

1. Log on to the computer that is running the instance of SQL Server 2005.
   
2. Click Start, point to All Programs, point to Microsoft SQL Server 2005, and then click SQL Server Management Studio.
   
3. Expand the computer name, expand Security, and then expand Logins.
   
4. Locate the following logins:
   • DomainName\PrivReportingGroup
     
   • DomainName\ReportingGroup
     
   • DomainName\SQLAccessGroup
   Notes
   • The DomainName placeholder represents the actual name of the domain in which the logins are located.
     
     
   • To determine the groups that belong to the Microsoft Dynamics CRM deployment that you want to delete, compare the complete names of these groups to the names of the groups that exist in the Active Directory. By default, the Active Directory groups exist in the OU that was created by the Microsoft Dynamics CRM server installation program. The group names in the Logins folder of SQL Server Management Studio contain the name and a GUID.
5. Delete the logins. To do this, right-click the login, click Delete, and then click OK.
   
6. Close SQL Server Management Studio.
   

Step 7: Remove the Microsoft Dynamics CRM subkeys
