SYSVOL and FRS

2 W2K DCs in a single domain. The replication AD and SYSVOL work fine. Since i have moved the SYSVOL folder in a another drive (applied recommandations of MS for this), the 2 DCs replicate all fine but for news DCs after DCpromo, the replication of SYSVOL is partial (on 60 GPOs, the replication begin immediatly for 30 GPOs, and for 7 GPOs 8 hours after but not all. Any ideas ?
