Displays the replication status when specified domain controller
     last attempted to inbound replicate Active Directory partitions.
             
     Status is reported for each source DC that the destination has an inbound 
     connection object from, grouped by partition. SHOWREPL helps administrators
     understand the replication topology and replication failures. 

     The REPADMIN console must have RPC network connectivity to all DC's 
     targeted by the DCLIST parameter. 

     Replication errors may be caused by the source DC, destination DC, DNS 
     or the underlying network. 

     The Windows Server 2003 and 2008 version of REPADMIN /SHOWREPL do not 
     display outbound intra-site replication partners as previous version did. 
     Use the /repsto parameter to display outbound partners. 

     [SYNTAX]

     /showrepl [DSA_LIST [Source DSA object GUID]] [Naming Context] [/verbose]
          [/nocache] [/repsto] [/conn] [/all] [/errorsonly] [/intersite] [/csv]
     
     [naming context] DN path of directory partition for which replication 
     status should be reported. By default, replication status is  
     reported on all partitions held by the destination DC.
      
     /verbose displays additional information about the source partners that 
     the destination DC inbound replicates from, including fully qualified 
     cname, invocation id, replication flags, USN OU and USN PU values. 

     /nocache - disbles translation of DC guid to friendly name.

     /repsto lists partner DC(s) that the targeted DC(s) outbound
     replicates to using change notification (i.e. DC's in the same 
     Active Directory site and DC's in remote sites where change notification 
     has been enabled) This list is appended under 
     "OUTBOUND NEIGHBOURS FOR CHANGE NOTIFICATIONS" of the repadmin output.      

     /conn appends a "KCC CONNECTION OBJECTS" section to repadmin output
     listing all connections and why they were created 
     

     /all - is equivalent to the /repsto and /conn options

     /errorsonly  - displays replication status only for source domain 
     controllers that the destination DC is encountering replication errors. 

     /intersite displays the replication status for connections from 
     out-of-site DC's that the DCLIST DC inbound replicates from 

     /csv formats the replication status in comma-separated value format where 
     it can be viewed in spreadsheets like Microsoft Excel or parsed by 
     reporting tools. 

    [EXAMPLES]

    Reports the inbound replication status for all DC's in the forest output 
    in CSV format

    repadmin /showrepl * /csv


    Reports the inbound replication status for all DC's 
    in the forest experiencing a replication error.

    repadmin /showrepl * /errorsonly

    Reports the inbound replication status for all DC's in the "HQ" 
    Active Directory site that inbound replicate a read-only or
    writable copy of the MAYBERRY.CONTOSO.COM domain partition.

    repadmin /showrepl site:HQ DC=Mayberry,DC=Contoso,dc=Com
