I would start looking at your systems, looking for the MPIO.sys version (1.22.3790.2358) and EMCMPIO.sys of 5.2.1.6 ( 5.2 SP1) that is one of the culprits. Again from what I gto fromt eh tier 3rd support etch at Microsoft yesterday from the poolmon dump that MPIO.sys was the culprit with the higher NPP counter, from what they saw therefore they wanted us to upgrade the EMC multipath drivers to V5.3 which includes a new version of MPIO.sys of 1.23.3790.2451 which is supposed to fix this situation.

We don't user Exchange and very few clustered systems, but almost everything is EMC attached using PowerPath, so this worries me.
