We are planning to update are XP clients from 4.9.0 sp2 to 4.9.1 sp2.
During testing I found that the NMAS tab did not show up, even though it
is enabled. When you look at the default profile and then the NMAS tab
it says the "NMAS client version: unknown". I checked and NMAS did get
install my the ACU.

Any ideas?
