What is the difference between replication of Sysvol and NTDS.dit database

hi,

what difference between sysvol replication , ntds.dit replication?  assume sysvol uses frs/dfs replicate gp, logon scripts etc between dc's , can see ntds replication occurs per pre-defined schedule (through sites , services) use dfs/frs services?

for example, if update user object on dc holding pdc emulator role -

1 - update ntds.dit file gets replicated other dc's per schedule?

2 - if so, if change not visible in gal, default period before gets updated?  link in ntds replication?

3 - exchange cached mode users, rather forcing gal update , downloading oab outlook, default period occur automatically , how can change this?

if update gpo or introduce script, i'm assuming replicated sysvol using frs/dfs?

i appreciate guidance! :-)

thanks all

1. ntds.dit database dosen't replicated, in fact ntds.dit database unique on each dc. information stored/updated within database replicates (some information dose not replicate however) using metadata indicate value on object has changed. other dcs can retrive list of added objects/changed values on network using rpc , getncchanges interface.

2. yes there other factors in terms of exchange server , outlook.

3. better ask question on in exchange forum.

assumptions gpos , script - you're right! (however gpo consists of 2 parts - 1 of part lives object in active directory , subject 1. above in terms of replication, other 1 lives in sysvol share , subject replication frs/dfs-r)
