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.)

  1. In Event Viewer, right click the Application Log.
  2. 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.
