Resolution
This issue occurs if theNetwork Service account is used as thefarm account. In this situation, when you remove Windows SharePoint Services 3.0 from a stand-alone farm, or when you remove SharePoint Server 2007 from aWindows SharePoint Services 3.0 farm environment, the followingregistry subkey that is used to encrypt passwords that are contained in the Windows SharePoint Services 3.0 configuration database (configdb) is deleted:
HKLM\SOFTWARE\Microsoft\Shared Tools\Web Server Extensions\12.0\Secure\ FarmAdmin\Therefore, when you try to join a Web application that exists in the configuration database that does not use the Network Service account, the Web application account credentials cannot be decrypted. This occurs because the required registry subkey is deleted.

at Microsoft.Crm.ObjectModel.CalculateBaseMoney.ProcessCalculatedColumns(DynamicEntity entity, BusinessEntity entityPreImage, EntityMetadata entityMetadata, String exchangeRateFieldName, Boolean isCreateOperation, ArrayList unchangedAttributes)
Resolution
This problem occurs because a money attribute is created for the entity. When you do this, Microsoft Dynamics CRM 4.0 creates an exchangerate attribute to work together with the money attribute. The money attribute is published as part of the entity. However, if you delete the money attribute, the exchangerate attribute is not removed. Therefore, when you try to run a Microsoft Dynamics CRM plug-in, the plug-in can find the exchangerate attribute. However, the plug-in cannot find the money attribute.
