Thank you, thank you, thank you, Tim and Bob! I've been struggling with this
error for many months. I thought I had searched for every permutation of the
error text on Bing, Google, and directly on
www.microsoft.com, but I still
missed this KB article. Today, I installed the hotfix you referenced and it
appears to have taken care of the problem.
Formerly, every time I had attempted to put my WinXP SP2 laptop (with 4GB of
RAM) into hibernation mode, the atttempt failed with an "Insufficient system
resources exist to complete the API" popup. In addition, the Windows Systems
Log would report an Information event with an Event ID of 26 and the same
text in the Description.
Prior to installing this hotfix, I had *never* been able to put this laptop
into hibernation mode--and I had even tried it right after a cold boot and
prior to running any applications (other than logging in). Since installing
the hotfix, I've tried loading numerous applications concurrently and am
happy to report that I'm still able to put the laptop into hibernation mode!
Thanks, again!
