我尝试发现服务端点 .../XRMServices/2011/Organization.svc 并且出现此错误:

An error has occurred.
Try this action again. If the problem continues, check the Microsoft Dynamics CRM Community for solutions or contact your organization's Microsoft Dynamics CRM Administrator. Finally, you can contact Microsoft Support.

由于您使用的是 NETWORK SERVICE，因此需要确保网络服务器的计算机帐户已添加到 Active Directory 中的 SQLAccessGroup。通常这是在 CRM 设置期间为您完成的，但如果您想稍后更改帐户，您必须记住手动将新帐户添加到该组。这是一个描述 CRM 使用的不同组的链接:
