RE: Question about functionality of the Exchange_DSAccessDC class

Hi Matt,

I created a repor and got the following results.

TEST1: Script executed at Exchange Server
============================================================================
========
(1) Test result when GC is up
and running
============================================================================
========
WINMGMTS:{authenticationLevel=pktPrivacy,impersonationLevel=impersonate}!\\B

Are you expecting similar results? if I understood correctly you see the
results as in (2) after an hour's delay?

Thanks,

| Hi Navneet,
| the answers to your questions are below. Thanks for looking this over:
|
| 1. We shut down (or make port 3268 unavailable on) the GCs Exchange
server
| is connected to. Then we wait for it to lose those connections. And then
we
| run the script that I posted in my original post. We also doublecheck the
| script output, by using DSAccess tab in ESM.
| 2. We run it on the Exchange server. (This shouldn't matter, I believe.)
| 3. We tried it on different Windows/Exchange versions this script can
| possibly run: Windows 2000 (SP2 and up) and Windows 2003 with Exchange
2000
| (SP2 and up) and 2003. Results are the same. The data available through
WMI
| (the script provided or DSAccess tab) reflects the actual situation afte
up
| to an hour delay.
