Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Windows Vista Service Pack 1.
The following details refer to the issue with certificate enrollment.
Windows Vista uses Task Scheduler (Taskeng.exe) to obtain the new certificate from the CA server by using a remote procedure call (RPC) connection. To create the RPC connection, the system must resolve the CA server name to an IP address. If the DNS suffix of the client computer differs from the DNS suffix of the CA server, the system may create a negative cache entry for the NetBIOS name of the CA server. In this situation, the client computer cannot contact the CA server because the system cannot resolve the CA server name.
To enable automatic certificate enrollment, follow these steps:
