Typing repadmin at a command prompt displays the following list of switches: 
Usage: repadmin <cmd> <args> [/u:{domain\\user}] [/pw:{password|*}]

Supported <cmd>s & args:
     /sync <Naming Context> <Dest DSA> <Source DSA UUID> [/force] [/async
            [/full] [/addref] [/allsources]
     /syncall <Dest DSA> [<Naming Context>] [<flags>]
     /kcc [DSA] [/async]
     /bind [DSA]
     /propcheck <Naming Context> <Originating DSA Invocation ID>
         <Originating USN> [DSA from which to enumerate host DSAs]
     /getchanges NamingContext [SourceDSA] [/cookie:<file>]
     /getchanges NamingContext [DestDSA] SourceDSAObjectGuid
          [/verbose] [/statistics]

     /showreps [Naming Context] [DSA [Source DSA objectGuid]] [/verbose]
         [/unreplicated] [/nocache]
     /showvector <Naming Context> [DSA] [/nocache]
     /showmeta <Object DN> [DSA] [/nocache]
     /showtime <DS time value>
     /showmsg <Win32 error>
     /showism [<Transport DN>] [/verbose] (must be executed locally)
     /showsig [DSA]
     /showconn [DSA] [Container DN | <DSA guid>] (default is local site)
     /showcert [DSA]

     /queue [DSA]
     /failcache [DSA]
     /showctx [DSA] [/nocache]

Note:- <Dest DSA>, <Source DSA>, <DSA> : Names of the appropriate servers
       <Naming Context> is the Distinguished Name of the root of the NC
              Example: DC=My-Domain,DC=Microsoft,DC=Com
For example, to determine to which domain controller a particular change has replicated, type the following line
repadmin /showmeta "CN=larryli,OU=DesignTeam,OU=Development,DC=ntbeta,DC=microsoft,DC=com" Name of DC
where Name of DC is the host name of the domain controller you want to check for the replicated parameters.

The output of this command is similar to: 
Loc.USN  Originating DSA  Org.USN  Org.Date/Time   Ver Attribute

By running this command against each domain controller, an administrator can determine whether all domain controllers have the same replicated values. If a specific domain controller does not have the same value, and the change was made some time ago, you can begin investigating why the computer has not yet received the change.
