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?
Regards,
Shivaraj
