Verifying Active Directory schema replication in Lync Server 2013
Topic Last Modified: 2012-10-29
Before you run forest preparation, manually verify that the schema partition has been replicated.
To manually verify schema replication
Log on to a domain controller as a member of the Enterprise Admins group.
Open ADSI Edit by clicking Start, clicking Administrative Tools, and then clicking ADSI Edit.
Alternatively, you can run adsiedit.msc from the command line.
In the Microsoft Management Console (MMC) tree, if it is not already selected, click ADSI Edit.
On the Action menu, click Connect to.
In the Connection Settings dialog box under Select a well known Naming Context, select Schema, and then click OK.
Under the schema container, search for CN=ms-RTC-SIP-SchemaVersion. If this object exists, and the value of the rangeUpper attribute is 1150 and the value of the rangeLower attribute is 3, then the schema was successfully updated and replicated. If this object does not exist or the values of the rangeUpper and rangeLower attributes are not as specified, then the schema was not modified or has not replicated.
