User replication between Servers

[cil1975]

Hi,
We have 2 Windows based Servers in our office ...
1. Windows 2008 Standard 64-bit server which is the Domain controller
2. Windows 2008 R2 64-bit which is another server in the same Domain.

We have synced the Active Directory of the Main DC with the other server. Earlier , when we would create a user in the main DC , it would get reflected in the other server ( since AD is synced ).
Of late, we have noticed that when a user is created it takes awful lot of time to get reflected in the other server. When we went to the Active Directory and Trusts module and did a Force replication , still nothing happened.
Would be glad to receive help on this topic

There is a time interval in which the sync happens. With our servers they would resync every 15 minutes between each other. Is it taking longer than 15 minutes?
