A SQL Server Timeout may occur when changing a name field for a Microsoft Dynamics CRM User

Increase the HKLM\Software\Microsoft\MSCRM\OLEDBTimeout to a higher value either on a temporary basis or permanent basis on the Microsoft Dynamics CRM Server.

Create or change the OleDbTimeout value

1. In Registry Editor, locate and then click the following registry subkey: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRM
2. Double-click the OleDbTimeout value
   
   Note If the OleDbTimeout value does not exist, create an OleDbTimeout value. To do this, follow these steps:
   1. Right-click MSCRM, point to New, and then click DWORD value
   2. Type OleDbTimeout
3. In the Edit DWORD Value dialog box, click Decimal, type 600 in the Value data field, and then click OK.
   
   Note The value of 600 represents 600 seconds. By default, the value is 30 seconds. Also note that if required on a temporary basis to allow this operation to complete, you may need to set this to 86400 which is equivalent to a value of 24 hours.

NOTE: It's recommended to run with the OLDDBTimeout setting set to a value between 30 to 600 decimal as a best practice to help minimize excessive SQL Blocking that a long running or expensive query may cause.
