Repadmin.exe Syntax

Repadmin uses the following general syntax:

Art Image repadmin Operation Parameters [/rpc] [/ldap][/u:Domain\User] [/pw:{Password | *}]

/rpc This parameter forces Repadmin to use an RPC session for network communications.

/ldap This parameter forces Repadmin to use an LDAP session for network communications if posable. If the LDAP connection fails then Repadmin attempts to connect using an RPC session. This is the default behavior for Repadmin.

/u Specifies the user name that has permissions to perform operations in Active Directory.

/pw Specifies the password for the user name entered with the /u parameter.

The DC_LIST Parameter

This section explains the syntax of the semi-global dc_list parameter

Art Image {dc_name**|** * |partial_server_name***| site:**site_name **|gc: |fsmo_**type:[name]}

dc_name Specifies the host name of a domain controller.

* Standard wildcard character. When this is used it returns all domain controllers in the enterprise. Improper use can cause a significant increase in network traffic.

partial_server_name* Partial wildcard character matching. For example, if given the partial domain controller name "woodgrovebank*", the wildcard character would return woodgrovebank-dc1 and woodgrovebank-dc2, but not woodgrove-diff-name.

****site:site_name The site: parameter takes the name of an Active Directory site (site_name), and returns all domain controllers in that site.

gc: Queries all Global Catalog Servers in the enterprise.

****fsmo_type:[name] Specifies a group of domain controllers to query by operations master (also know as flexible single master operations or FSMO) type. Valid operations master types follow.

Operations Master Type	Description
fsmo_pdc:[name]	Runs the repadmin.exe command against the PDC Emulator. The name parameter takes a naming context.
fsmo_rid:[name]	Runs the repadmin.exe command against the RID operations master. The name parameter takes a naming context.
fsmo_im:[name]	Runs the repadmin.exe command against the IM operations master. The name parameter takes a naming context.
fsmo_istg:[name]	Runs the repadmin.exe command against the ISTG operations master. The name parameter takes a site DN.
fsmo_dnm:	Runs the repadmin.exe command against the DNM operations master.
fsmo_schema:	Runs the repadmin.exe command against the Schema operations master.

Parameters

DC_LIST Specifies the host name of a domain controller or a list of domain controllers separated by a space. See above for detailed syntax.

/async Specifies that replication will be asynchronous. This means that Repadmin starts the replication event, but it does not expect an immediate response from the destination domain controller. Use this parameter to start kcc and not wait for it to finish.

Repadmin latency

Displays the amount of time between replications using the ISTG Keep Alive timestamp.

Notes

These time stamps are not used in Windows Server 2003 Native Mode, and results are inaccurate.
In Windows Server 2003 Native Mode, the repadmin /showutdvec /latency is used in place of the operation.

Art Image repadmin /latency [DC_LIST] [/verbose]

Parameters

DC_LIST Specifies the host name of a domain controller, or a list of domain controllers separated by a space. See above for detailed syntax.

/verbose Lists detailed information.

NamingContext Specifies the distinguished name of the directory partition on the source domain controller.

first The number of seconds after a change is made before the domain controller notifies its first replication partner that there is a change.

subs Once the first replication partner is notified of a change, the subs parameter specifies the number of seconds to wait before notifying the next replication partner.

Repadmin options

Changes default Knowledge Consistency Checker (KCC) behavior on the NTDS Settings object of a domain controller.

Syntax for /options is available by typing:

repadmin /experthelp

Important

Setting these options might impair or disable the ability of the KCC to calculate the topology automatically. These options are intended for use by advanced administrators for special situations. If you set these options, document the settings carefully to ensure that the KCC functions as expected and can be restored to default functionality if necessary.

Repadmin removelingeringobjects

Uses an authoritative domain controller to compare the directory of a domain controller (destination) that is suspected of having lingering objects against the directory of a domain controller (source) that is designated as a reference source for up-to-date values for the domain of the destination. When the advisory mode parameter is used, this command provides a list of found lingering objects. When the advisory mode parameter is not used, this command removes lingering objects from the destination domain controller.

Syntax for /removelingeringobjects is available by typing:

repadmin /experthelp

Important

To use the repadmin /removelingeringobjects command, both source and destination domain controllers must be running Windows Server 2003.

Art Image repadmin /removelingeringobjectsDestination_DC_ListSourceDCGUID NamingContextDN /advisory_mode

Parameters

Note

"Destination" in the context of this syntax does not indicate a destination replication partner, but rather a source replication partner that is suspected of having lingering objects. The term "destination" identifies the server as the focus of the lingering object removal process.

Destination_DC_List Specifies the host name of a destination domain controller, a list of domain controllers separated by a space, or * for all domain controllers in the enterprise. See above for detailed syntax.

SourceDCGUID Specifies the GUID of the source (reference) domain controller that will be used to identify objects that are outdated (lingering) on the destination. Obtain the GUID by running repadmin /showrepl against the source domain controller that you are using as the reference server.

NamingContextDN Specifies the distinguished name of the directory partition from which the lingering objects are to be removed.

advisory_mode Prints a list of objects that are found in the directory of the destination domain controller that are not found in the directory of the source domain controller. Objects are not removed if this parameter is used.

Repadmin replicate

Starts a replication event for the specified directory partition between the source and destination domain controllers. The source UUID can be determined when viewing the replication partners by using the Repadmin showrepl operation.

Syntax 1

Art Image repadmin /replicateDestination_DC_LIST Source_DC_NAME [/force] [/async] [/full] [/addref]

Syntax 2

Art Image repadmin /replicateDestination_DC_LIST [/force] [/async] [/full] [/addref] [/allsources]

Parameters

Destination_DC_LIST Specifies the host name of the destination domain controller (Directory Server Agent) with which you want to replicate. See above for detailed syntax on the DC_LIST parameter. This parameter cannot be used with /allsource.

Source_DC_NAME Specifies the host name of the source domain controller with which you want to replicate. This parameter accepts a GUID, GUID-based DNS name, or the name of a server object.

/force This parameter is used to override the Disable Replication option on a server.

/async Specifies that the replication will be asynchronous. This means that Repadmin starts the replication event, but it does not expect an immediate response from the destination domain controller. Use this parameter when there are slow links between domain controllers.

/full Forces a full replication of all objects from the destination domain controller.

/addref Directs the source to check for a notification entry on the source. If the source does not have a notification entry for this destination, one is added.

/allsources A given destination can have multiple sources for the same naming context. Directs the destination to sync with all sources instead of just one. This parameter cannot be used with Destination_DC_LIST

/readonly This parameter is ignored by the /replicate operation.

Repadmin replsingleobj

Replicates a single object between any two domain controllers that have partitions in common. The two domain controllers do not have a replication agreement. Replication agreements can be shown by using the Repadmin /showrepl command.

Art Image repadmin /replsingleobject [DC_LIST] DsaSourceGUID ObjectDN

Parameters

DC_LIST Specifies the host name of a domain controller or a list of domain controllers separated by a space that the object will be replicated to. See above for detailed syntax.

DsaSourceGUID Specifies the unique hexadecimal number that identifies the object that will be replicated. The objectGUID can be retrieved by using the showrepl operation.

ObjectDN Specifies the distinguished name of the object.

Repadmin replsummary

The replsummary operation quickly and concisely summarizes the replication state and relative health of a forest.

Art Image repadmin /replsummary [DC_LIST] [/bysrc] [/bydest] [/errorsonly] [/sort:{delta | partners | failures | error | percent}]

Parameters

DC_LIST Specifies the host name of a domain controller or a list of domain controllers separated by a space that the object will be replicated to. See above for detailed syntax.

/bysrc This parameter shows the output of the repadmin.exe/replsummary command, from the perspective of the replication source, in the form of a table. This means that a given source server is "pulled on" by multiple client computers. The table is sorted in order of the source computers that are having the most problems, across all the clients in the forest. This parameter does not display the destination domain controller.

/bydest This parameter shows the output of the repadmin.exe/replsummary command, from the perspective of the replication destination, in the form of a table. This means that the "client" is pulling the changes from a replication source or "server", and the table shows the inbound systems, and what problems they are having with their partners. The table is sorted in the order of the inbound systems that are having the most problem with inbound replication, across all the possible partners in the forest. This parameter does not display the source domain controller.

/errorsonly Shows only the domain controllers where the partner error is non-zero.

/sort:{delta| partners| failures| error| percent} Sorts the replsummary table by the specified column heading.

Notes

The /bysrc and /bydest parameters may be specified at the same time. If this is done, then Repadmin displays the /bysrc table first and the /bydest table next.
If the parameters /bysrc and /bydest are both absent, Repadmin picks the best one, and displays the one with the least number of partner errors.

Repadmin showattr

The /showattr operation displays the attributes of an object.

Art Image repadmin /showattr DC_LIST [OBJ_LIST] [OBJ_LIST_OPTIONS] [/atts:attribute,attribute,...] [/allvalues] [/long] [/nolongblob] [/nolongblob] [/nolongfriendly] [/dumpallblob]

Parameters

DC_LIST Specifies the host name of a domain controller or a list of domain controllers separated by a space that the object will be replicated to. See above for detailed syntax. This is a required parameter.

OBJ_LIST This parameter takes a DN or a special keyword that expands into a DN. The keywords are:
- Ncobj:config:
- Ncobj:schema:
- Ncobj:domain: This key word is the domain partition DN of the home server.
- Dsaobj: This keyword is the NTDS settings object of the home server.

OBJ_LIST_OPTIONS The OBJ_LIST_OPTION parameter is required to perform a generic LDAP search from the command line. The parameter requires a Base DN, with the ability to use a search modifier option. The valid search modifier options are as follow:
- /filter:<ldap_filter>
- /base
- /subtree
- /onelevel
See the LDAP documentation for the LDAP filter syntax.

****/atts:<attributes,attributes,... Returns only the attributes specified. Separate each listed attribute with a comma.

/allvalues For an attribute, the tool only displays 20 values unless this flag is specified, in which case it shows all values.

/long Displays one value per line.

/nolongblob This parameter is ignored by the /showattr operation.

/nolongfriendly This parameter is ignored by the /showattr operation.

/friendlyblob[:attributeattribute...] If any attributes are specified, only those attributes named are displayed in friendly format. Otherwise all known blobs are formatted.

/nolongfriendly Does not format blobs.

/dumpallblob Dumps the blob in a default byte-by-byte format if there is not a friendly formatted interpretation available for it.

/nodumpallblob Does not show the blob if there is not a formatted interpretation available.

Note

A blob in this context means an attribute that is not a simple type, like a string or an integer. A blob is a complex structured type that is stored as binary bytes. In order to make sense of the blob, a program must interpret it and format it. A friendly blob is a blob that the program knows about and can format in an understandable way. The program has a list of blobs that it understands.

Repadmin showcert

Displays the server certificates loaded on a specified domain controller.

Art Image repadmin /showcertDC_LIST

Parameters

DC_LIST Specifies the host name of a domain controller or a list of domain controllers separated by a space that the object will be replicated to. See above for detailed syntax. This is a required parameter.

Repadmin showchanges

Displays changes from a specified directory partition or changes to a specified object. Syntax 1 saves changes to a directory partition. If this information is saved to a file the getchanges operation can be run again for comparison. Syntax 2 lists changes to a specified object.

/verbose Lists detailed information.

/statistics Displays a summary of information about changes instead of a list of individual changes.

/noincremental Returns changes in value change format, which lists current values for attributes as well what attributes have been added or deleted. If not specified, changes are returned in attribute change format, which shows only the current value of the attribute.

/objectsecurity Overrides the need for the Get Changes right to the directory partition. By default this right is needed to run the GetChanges parameter. However, only changes that the currently logged on user has the rights to view are displayed.

/ancestors Returns changes in USN order.

****/filter:ldap filter Returns only those changes that meet the filter requirements.

Note

The information from Syntax 1 can be saved to a file for later comparison.

[{+|-}IS_SCHEDULE_HASHING_ENABLED]

[{+|-}IS_REDUNDANT_SERVER_TOPOLOGY_ENABLED]

{+|-}W2K3_IGNORE_SCHEDULES {+|-}W2K3_BRIDGES_REQUIRED

Parameters

DC Specifies the host name of the domain controller on which to set the site options.

SiteName The site that the option setting affects.

{+|-}IS_AUTO_TOPOLOGY_DISABLED When enabled, prevents the KCC from generating intrasite connections on all servers in the site. Disable this option if you use manual connections and do not want the KCC to build connections automatically.

{+|-}IS_TOPL_CLEANUP_DISABLED When enabled, prevents the KCC from removing connection objects that it does not need. Disable this option if you want to take responsibility for removing old redundant connections. Alternatively, to control or augment the topology, you can use manual connections, which the KCC does not delete.

{+|-}IS_TOPL_MIN_HOPS_DISABLED When enabled, prevents the KCC from generating optimizing connections in the ring topology of intrasite replication. Optimizing connections reduce the replication latency in the site and disabling them is not recommended.

{+|-}IS_TOPL_DETECT_STALE_DISABLED Prevents the KCC from excluding servers that are unreachable from the topology; that is, the KCC does use an alternate server to reroute replication. Use this option only if network communication is very unstable and brief outages are expected.

{+|-}IS_INTER_SITE_AUTO_TOPOLOGY_DISABLED Prevents the KCC that functions as the intersite topology generator (ISTG) from generating connections for intersite replication. Use this option when you want to create manual intersite connections (disable the ISTG) but retain the KCC to generate intrasite connections.

{+|-}IS_GROUP_CACHING_ENABLED Disables Universal Group Membership Caching in the site.

{+|-}FORCE_KCC_WHISTLER_BEHAVIOR Implements KCC operation that is consistent with Windows Server 2003 forest functional level. This option can be set if all domain controllers in the site are running Windows Server 2003.

{+|-}FORCE_KCC_W2K_ELECTION Off by default. When enabled, implements the Windows 2000 Server method of ISTG selection.

{+|-}IS_RAND_BH_SELECTION_DISABLED Implements the Windows 2000 Server method of selecting a single bridgehead server per directory partition and transport.

{+|-}IS_SCHEDULE_HASHING_ENABLED Spreads replication start times randomly across the entire schedule interval rather than just the first quarter of the interval.

{+|-}IS_REDUNDANT_SERVER_TOPOLOGY_ENABLED Creates redundant connections between sites before a failure takes place. When enabled, disables KCC failover. Requires that automatic detection of failed connections also be disabled (+IS_TOPL_DETECT_STALE_DISABLED).
