Microsoft Knowledge Base Article 813338 contains the following summary:

For domains with many policies and domain controllers with slow wide area network (WAN) lines, replicating the SYSVOL share can take a long time. This is most noticeable when you promote a new domain controller at a location with slow connectivity or when you run a non-authoritative restore of SYSVOL. To speed up the process, reduce the number of files and amount of data that must be replicated in the SYSVOL share.

Because Administrative Templates (that is, .adm files) take up the most space in policies, remove them to significantly reduce the size of SYSVOL. For example, with the default Administrative Templates, each policy takes up 870 kilobytes (KB) of disk space. If you have 1,300 policies, you can reduce the size of SYSVOL from 1,100 megabytes (MB) to 35 MB (or 27 KB per policy).

You can use Group Policy settings to change the behavior of Group Policy Editor regarding .adm files in Microsoft Windows Server 2003.For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
