MORE INFORMATION

The warning in the "Symptoms" section is not an indication of a failed operation or loss of functionality. The store recovers gracefully from the condition. If you perform the instructions in the "Resolution" section, you can prevent the condition that leads to the Application log warnings.

The post-SP3 store hotfix resolves a number of issues that can cause 1025 Events in the EcGenerateNRN and EcGenerateReadReport functions. The hotfix includes a new version of Isinteg.exe that can fix the apparent problem that generates the events listed in the "Symptoms" section.

The updated files include the following files and versions:

File name	File version
Store.exe	5.5.2652.42
Isinteg.exe	5.5.2652.33

Note that the 1025 Event is a generic warning event, and that this article only applies if the function name and error code match.
