Performance Monitor Counters

Hello,

We are about to do some performance testing of BizTalk Server 2006 R2

running on W2K3. When I run Perfmon, I see 5 BizTalk-related performance

objects. When I select an object, then go to select individual counters,

almost all of them are not available, evidenced by the Add button being

disabled. Can anyone tell me why the counters are disabled, and how can I

enable them? Again, this is specific to BizTalk counters.

TIA,

DetRich
