Hello and potential word to the wise:
We experienced a fairly heavy impact on all of our cache map and image services after applying the February MS update titled above. I beleive the KB:
Vulnerability in Microsoft Graphics Component Could Allow Information Disclosure (3029944)
This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow information disclosure if a user browses to a website containing a specially crafted TIFF image. This vulnerability would not allow an attacker to execute code or to elevate their user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.
Caused some type of conflict that affected the ability of ArcServer to read all of the source rasters from our Imagery Share. All day we experienced tile draw errors (large and small empty squares) after applying this update to our Windows Server 2008R2 file server. Of course, these tiffs in turn source all of our ImageMosaics that in turn source all of our Image Services.
I suspect once ArcServers ability to read the source rasters was affected, that then affected all of our cache services such that we had suffered draw errors accross the board as the ArcServer logs reported draw errors all day.
We rolled back the updates, rebooted the machine and all seems fine now.
