We currently have a farm with three web front ends, there is a
discrepancy between the recognized files between them. The unusual
thing is the file types we are having problems with is office 2007,
basically any of the extensions that end with x (i.e docx xlsx etc).
These should be automatically recognized files types by MOSS. We have
one WFE that recognizes the files without any problems the other two do
not. We have tried installing the filter pack with no changes noticed,
any insight or help would be greatly appreciated.
