Using the standard GUI Microsoft Management Consoles toÂ makeÂ the change toÂ speed up Active DirectoryÂ replicationÂ is not possible. The best result of usingÂ administratorÂ consoles will be toÂ increase domainÂ replicationÂ between domainÂ controllersÂ to 15 minutes.Â TheseÂ large time values were instituted into Active Directory at version 1 becauseÂ inter-siteÂ connectionsÂ during that era of computing and networking were muchÂ lower in bandwidth with the most common being frame-relay or 56kÂ circuits. Since then,Â inter-siteÂ connectionsÂ and the Internet speeds have increasedÂ tremendously so faster domain controller replication is possible even over wan links.
