Description:

If you install a new exchange system or change your existing exchange system by for example adding a new server in a domain that is already administered by Admin, you will not see it. The only way to be able to see the Exchange server by using the Admin Manager is to delete the relevant namespace and recreate it.

Solution:

The database of CA Admin is a directory. This means we can use LDAP commandoes against it. And admin is delivered with a few command line ldap utilities. And with use of a simple ldap command we can easily tell CA Admin to do a new explore that will register any new exchange server and that will keep existing data.

ldapsearch -h ADMINSERVER -p 20389 -D "eTGlobalUserName= ADMIN_ADMINISTRATOR ,eTGlobalUserContainerName=Global Users,eTNamespaceName=CommonObjects,dc= ADMIN_DOMAIN_NAM E,dc=eta" -w PASSWORD -b eTADSDirectoryName= ADEXchangeDirectory ,eTNamespaceName=ActiveDirectory,dc =ADMIN_DOMAIN_NAME ,dc=eta -s base (objectClass=eTADSDirectory) eTADSexchangeStores eTExploreUpdateEtrust

By running the above command (everything on one line) you will issue a new explore that will discover any new exchange servers. Remember to change the variables that are marked as bold.

Remember that the user ID registered in the properties sheet of the AD namespace under the tab "ADS Server" does need to have the following rights on the AD system:

  • AD Domain Administrator

  • Exchange Administrator
