Abstract:
|
||
|
|
|
||
|
|
The ISA setup needs to successfully open the SharedAccess service and get the
|
||
|
|
its status in order to succeed. But on whistler we remove this from advanced
|
||
|
|
server since it's a consumer feature so the ISA setup bails out.
|
||
|
|
|
||
|
|
We fake the service API call return values to make the ISA setup happy.
