SYMPTOMS
In some cases, intrasite replication may appear to be slow or take up to two hours to complete. By default, Replication Latency is set to 300 seconds, plus 30 seconds per server in the site.



CAUSE
The unusual latency can be attributed to many factors, including network bandwidth saturation or name resolution problems. Other factors that cause the latency may have to do with Remote Procedure Calls (RPC).



WORKAROUND
The Microsoft Exchange Server 5.5 release notes state that you must run Windows NT 4.0 SP3 to install Exchange Server 5.5. It is also strongly recommended that you at least install the Windows NT 4.0 post-SP3 fix before installing Exchange Server 5.5 in your environment. This fix can be downloaded from the following location:

http://www.microsoft.com/ntserver/nts/downloads/archive/NT4y2kpostSP3/default.asp

Note: If you install a new Windows NT component, you should reapply the service pack and any post-SP3 fixes. Windows NT SP4 or SP5 can be applied instead of Windows NT SP3 and the post fixes.
