Question:

What is the difference in between  SYSVOL and NETLOGON folders speaking of ACTIVE directory?

Answer:

IN Active directory there are two critical folders which are shared by each domain controller. These folders are SYSVOL and NETLOGON.

Now,

SYSVOL, is used by the domain clients Windows 2X and upper versions to apply GPO ( Group Policies) When you create GPO from DC1 , the GPO gets put into this folder so that it can be replicated to other domain controllers within your Domain name space.

NETLOGON, is used by domain clients to obtain logon script, same goes for the logon scripts when you configure one logon script same scrip gets copied via network connectivity by FRS to other domain controllers

Now AD replication scope is Forest-wide, while SYSVOL replication scope will be Domain wide. The replication problems in AD may cause replication issues problems inconsistent SYSVOL and this will be bad effect to your environment.

FRS uses same connection objects and scheduled , except same site partners, Which Active directory replication uses, so no wonder when AD replication is having issues, so does SYSVOL replication gets effected by this problem. AD replication topology could lead to SYSVOL replication failure.
