Help with AD schema extensions for Vista wireless

Hello,

I am planning for add the Vista wirless AD scema extensions. I am new to

this and am hoping for a little feedback. We have a server 2003 R2 domain. I

have the white papaer on making this change and it seems pretty straight

forward. One problem is I do not have the luxary of a testing environment.

The second is I'm still a little foggy on a disaster recovery plan. It seems

that you can not restore schema info but only disable additions you make, is

this true? Also, if anyone has done this before please lend a helping hand.

Thanks in advance.
