What is an RODC server?
What is an RODC server?
A read-only domain controller (RODC) is a server that hosts an Active Directory database’s read-only partitions and responds to security authentication requests.
Why RODC is required?
The main reason for using an RODC is mainly for security purposes, while also providing domain resiliency at remote offices. If a remote office has poor physical security or is only serving a small number of very non-IT minded staff, there is no good reason to have a fully writable domain controller onsite.
How does a RODC work?
If the password is cached, the RODC will authenticate the user account locally. If the user’s password is not cached, then the RODC forwards the authentication request to a writable Windows Server 2008 Domain Controller which in turn authenticates the account and passes the authenticated request back to the RODC.
What does RODC stands for and its main purpose?
What is RODC and what are its advantages?
The main benefits of an RODC are as below: Reduced security risk to a writable copy of Active Directory. Better logon times compared to authenticating across a WAN link. Better access to the authentication resource on the network. Better performance of directory-enabled applications.
Can a RODC be a global catalog server?
RODC can be promoted as Global Catalog. However, certain directory-enabled applications do not support an RODC as a global catalog server.
How do I run KCC?
To force the KCC to run, perform the following steps: 1. In Active Directory Sites and Services, in the console tree, expand Sites, expand the site that contains the server on which you want to run the KCC, expand Servers, and then select the server object for the domain controller that you want to run the KCC on.
How do I sync a domain controller?
To manually run synchronization with the Active Directory domain controller:
- In the application web interface, select the Settings → External services → LDAP server connection section.
- Click Synchronize now.
What is RODC Why do we configure RODC?
The RODC is designed specifically to address the branch office scenario. An RODC is a domain controller, typically placed in the branch office, that maintains a copy of all objects in the domain and all attributes except secrets such as password-related properties.
How does RODC improve an organization’s security?
Reduced security risk to a writable copy of Active Directory. Better logon times compared to authenticating across a WAN link. Better access to the authentication resource on the network. Better performance of directory-enabled applications.
What is rodc in Windows Server 2008?
Windows Server 2008: Read-Only Domain Controller (RODC) A Read-Only Domain Controller (RODC) is a new type of domain controller in Windows Server 2008. Its main purpose is to improve security in office branches.
How does a rodc store passwords?
This single record will then be replicated from the writable DNS server to the RODC DNS server. By default, an RODC doesn’t store user or computer credentials. (The only exception is the computer account of the RODC itself and a special krbtgt account.) However, an RODC can cache passwords.
How does the rodc DNS server work?
If a client wants to update its DNS record, the RODC will send a referral for a writeable DNS server. The client can then update against this DNS server. This single record will then be replicated from the writable DNS server to the RODC DNS server.
Does it make sense to work with rodcs?
There are certainly environments where it makes sense to work with RODCs. Big companies with Active Directory specialists probably won’t be afraid of the increased complexity. However, since bandwidth gets cheaper almost every day, it is probably only a matter of time until domain controllers in branch offices will not be necessary anymore.
