- all features were running on sitecollection level and at site level
But here is the solution, i do not why it worked but it did work.
Although you can activate and deactivate Office SharePoint Server Enterprise Site Collection features , Office SharePoint Server Enterprise Site features through site collection features and site features.
But give it a try through STSADM Solution:
stsadm -o deactivatefeature -filename IPFSSiteFeatures\feature.xml -force -url %SITE_COLLECTION_URL%
stsadm -o deactivatefeature -filename IPFSWebFeatures\feature.xml -force -url %SITE_COLLECTION_URL%
STSADM.EXE -o activatefeature -filename IPFSSiteFeatures\feature.xml -url %Sitecollection_URL% -force
STSADM.EXE -o activatefeature -filename IPFSWebFeatures\feature.xml -url %sitecollection_URL% -force
