bpsetconfig: worked with Unix master but not Windows master?

Hi all,

In the past I was in a mostly *nix environment and had no problems pushing out exclude list updates to Windows clients from Unix masters.  When I try the same thing with a Windows master, the command does not fail but it doesn't update the client, either.  i.e.

bpgetconfig -M <client> exclude   <---- shows me the current exclude list

bpsetconfig -h <client> file_with_new_excludes <------- returns a 0 status but when I run bpgetconfig again nothing has changed.

Any ideas here?  This is with NBU 7.5.0.5
