I recently had to fight with an issue on a Windows 2012 Server with IIS 8, and a web site that kept on forcing the user to type in authentication credentials to access a PDF file located in a subdirectory.

I did the usual checks:

1. NTFS permissions to IUSR
2. Anonymous access allowed on the web site

See this earlier post.

I have not taken a huge amount of photos with my Chinese brand microscope during the time I owned it. Therefore a comparison is hard to make. I recently encountered the same algae (Asparagopsis taxiformis - Falkenbergia Stage / Sporophyte Stage) than I had in one of my first reef aquariums, so this presented a good test case to see just how much you get for the additional cost of a research grade microscope.

All the old photos were taken with a $500 Chinese brand microscope coupled with a $400 2.1MP Motic CCD. All new photos were taken with an Olympus BX53 microscope with UPlanSApo objectives and a Canon 600D camera. The old photos used bright field illumination, the new photos used DIC.

These polyps measure at most 4mm across.

I recently started getting these failures on a server I manage. The error in Windows Backup states:

Creation of the shared protection point timed out. The shared protection point operation failed with error 0x81000101.

The event log had this:
