MAPI problem with HrGetServerDN

shivaraj · Joined: 05 Aug 2007 Posts: 20

Hi,

1. From where does HrGetServerDN fetches its value?

2. From the return value of HrGetServerDN "/o=First Organization/
ou=First Administrative Group/cn=Configuration/cn=Servers/cn=SRMSE3"
is "/o=First Organization/ou=First Administrative Group/
cn=Configuration/cn=Servers/" common across any exchange servers?

I would have thought that you would have researched this before you started
programming? It retrieves the distinguished name (DN) for a server from the
directory. MSDN is your friend.

In my case I have 2 EVS (EVS1 AND EVS2) configured. If both EVS are
active on host1 then how should i make HrGetServerDN connect to EVS2
Instance? If this sentence is confusing please see below detail.

I have exchange cluster in which I wish to get mailboxes for EVS1 and
EVS2. To make this, I am creating 2 different profiles (say EVS_PROF_1
and EVS_PROF_2) by mentioning EVS1 and EVS2 as server names. And i
made EVS1 active on host1 and EVS2 active on host2 ( host3 is my
cluster backup node) . Now if i want to get servername programatically
( to get mailboxes from EVS1 (on host1) and mailboxes from EVS2 (on
host2) ) using HrGetServerDN, I am getting servername as EVS1 on both
host1 and host2. Why this is so?

Since i did not get answer for this problem, I thought of using
hardcoded HrGetServerDN value in my code ( since HrGetServerDN will
return "/o=First Organization/
ou=First Administrative Group/cn=Configuration/cn=Servers/cn=EVS1" as
result, I am hardcoding this value as "cn=Configuration/cn=Servers/
cn=EVS1" and cn=Configuration/cn=Servers/cn=EVS2" in my code. This
will fetch mailboxes proeprly from EVS1 and EVS2 properly. So my
question was "IS THIS OK IF I HARDCODE "cn=Configuration/cn=Servers/
cn=" IN MY CODE ?

Cheers,
Shivaraj

Your question now is "So my question was "IS THIS OK IF I HARDCODE
"cn=Configuration/cn=Servers/cn=" IN MY CODE ?". Perhaps you should read
your own email.. What you asked was.

1. From where does HrGetServerDN fetches its value? --> I told you the
directory.
2. From the return value of HrGetServerDN "/o=First Organization/ou=First
Administrative Group/cn=Configuration/cn=Servers/cn=SRMSE3" is "/o=First
Organization/ou=First Administrative Group/
cn=Configuration/cn=Servers/" common across any exchange servers? --> Yes

So you got your answer!

Now you are asking if you can hardcode it. Well it is obvious that you have
not tried this or your would have gotten your answer which is also yes.

Hi Dgoldman,

Thanks for your answers.

I tried using this hardcoding stuff in my code and it worked. But in
one google group i noticed that we can even use "cn=Configuration/
cn=Servers/cn=EVS2" instead of the complete "/o=First Organization/
> > ou=First Administrative Group/cn=Configuration/cn=Servers/cn=EVS2" as the First Organization and First Administrative Groups might very from one exchange server to other. So in that case my code might fail.
I just tried using only "cn=Configuration/cn=Servers/cn=EVS2" and
the complete name (including first organization etc)...both worked for
me. So i just wanted to confirm which one will be good to use? In my
view, if i just use "cn=Configuration/cn=Servers/cn=" as hardcoded
part and append whatever server i want to this, then this code will
work for any exchange server. Am i right? I want to know the differece
between mentioning and not mentioning "/o=First Organization /ou=First
Administrative Group"

Regards,
Shivaraj
