LcsCmd.exe /forest /action:SchemaPrep
3.Use the following command to verify that schema preparation ran to completion.
LcsCmd.exe /forest /action:CheckSchemaPrepState
4.Wait for Active Directory replication to complete or force replication.
5.Manually verify that schema preparation ran successfully and that the schema changes replicated to all other domain controllers, as described in the following procedure.
To manually verify schema preparation and replication
1.Log on to controller member server as a member of the EnterpriseAdmins group.
2.Open ADSI Edit by clicking Start, clicking All Programs, clicking Administrative Tools, and then clicking ADSI Edit.
Alternatively, you can run adsiedit.msc from the command line.
3.In the MMC console tree, click ADSI Edit (that is, if it is not already selected).
4.On the Action menu, click Connect to.
5.In the Connection Settings dialog box under Select a well known Naming Context, select Schema, and then click OK.
6.Under the schema container, search for CN=ms-RTC-SIP-SchemaVersion. If this object exists, and the value of the rangeUpper attribute is 1008, then the schema was successfully updated and replicated. If this object does not exist or the value of the rangeUpper attribute is not equal to 1008, then the schema was not modified or has not replicated.
