A low disk space condition can be due to many different things, such as:
Resolution
Check the registry on the server to determine the disk volume that contains the Active Directory database. Under the HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NTDS\Parameters registry key, the value DSA Database file contains the path of the file in which Active Directory keeps its database. If the Active Directory database is stored on the C: drive and this is the same drive that contains the system TEMP directory (usually C:\TEMP), delete all of the files in the TEMP directory.
Determine what directories are using the most disk space. Using Windows® Explorer, right-click on each directory and select Properties. The disk space used by the directory sub-tree will appear on the Properties page. After you determine what is causing the directories to grow, run Ntdsutil.exe to compact files, move files to another volume, or move transaction logs to another volume.
