To work around this issue, in the registry, make sure that the ImagePath value for the service that returned the error message does not contain any extra characters or spaces. To do so, you have to use Registry Editor.

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:
To make sure that the ImagePath value for the service that returned the error message does not contain any extra characters or spaces:

1.	Start Registry Editor (Regedt32.exe).
2.	Locate the ImagePath string value under the following key in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MSExchangeIS NOTE: This step applies to any service under the Services key in the registry.
3.	Open the ImagePath value on the right, and then make sure that it does not contain any extra colons (:), spaces, or characters. The following is an example of correct string value for the Exchange Information Store service: C:\Exchsrvr\Bin\Store.exe
4.	Quit Registry Editor.
