File Replication Service is scanning the data in the system volume. Computer %1 cannot become a domain controller until this process is complete. The system volume will then be shared as SYSVOL. To check for the SYSVOL share, at the command prompt, type net share. When File Replication Service completes the scanning process, the SYSVOL share will appear. The initialization of the system volume can take some time. The time is dependent on the amount of data in the system volume
