Can not see entries in Application Log in Event Viewer
Solution 1:
Based on Shane Madden's answer but with no restart required... (This is an e-commerce production server, so we can't restart easily.)
- In Event Viewer, right click the Application Log.
- Change the name of the log. I added _2 at the end.
Solution 2:
2^64 is near the number that you're seeing. Coincidence? I think not!
Sounds like the log's definitely corrupt; your best bet may be to just nuke it (see here) and start clean.
