IIS7 GZIP Compression not working? Fixed!

November 15th, 2009 admin

Well this one took a while to track down!!

I’ve been looking at a problem with 2008 where after enabling compression in IIS – javascript and css files still weren’t getting compressed.    Enabling Failed Request Tracking showed “UNKNOWN_ERROR” when trying to compress the files(helpful!).

After two days of searching – I eventually found another reference to the problem (along with a fix) here:

Turns out that as a result of hardening the server – permissions to the C: root had changed – and there’s a call to GetVolumeInformation which fails due to this.

Windows Update Failing With Error 646?

I’ve seen a couple of machines reporting this error now recently.   Looking on google I’m not alone as there appear to be reports popping up all over the place!

The most successful solution I’ve seen so far is to download each update and manually install it.   I’m still searching for a better solution as this could be very tedious for a lot of PCs!   I’ll report back when I have further information.

For now – here is some further reading:
