CRMWeb Login Error

This issue is caused by a permissions error and usually happens after a Windows update.  The windows update changes the ASPNET password for CRM in the Machine.Config file which is part of the .Net framework.

Note: This only applies to IIS5 or IIS6 in 5.0 Isolation Mode.

Solution

1. Check the Machine.Config file for the ASPNET password.  This file can be found in:
   
   C:\Windows\Microsoft.NET\Framework\v2.0.50727\Config or
   C:\WinNT\Microsoft.NET\Framework\v2.0.50727\Config
   
2. Search for the "process Model" node in the Machine.Config file:
   
   <system.web>
      <process Model autoConfig="true" userName="ASPNET" password="Your Password" />
   
3. Change the password to your known ASPNet user password or put in a new one.  If the password is "ABC123def" then this line should look like:
   
   <process Model autoConfig="true" userName="ASPNET" password="ABC123def" />
   
   
4. Make sure the password matches the ASPNet user in both the RDP data server and the CRM web server.  Go to Start | Programs | Administrative Tools | Computer Management on the RDP data server and the CRM web server and reset the password to the same password entered in step 1.
   
   
5. Go to Start | Programs | Administrative Tools | Internet Information Systems (IIS).
   
   
6. Restart IIS.
   
   
7. Test the CRM Web login.
