DFS Management in Windows Server 2008 includes the ability to run a propagation test and generate two types of diagnostic reports—a propagation report and a general health report:
-
Propagation test Tests replication progress by creating a test file in a replicated folder.
-
Propagation report Generates a report that tracks the replication progress for the test file created during a propagation test.
-
Health report Generates a report that shows the health of replication and replication efficiency.
Follow this procedure to create a diagnostic report for DFS replication.
 | To create a diagnostic report for DFS replication |
Click Start, point to Administrative Tools, and then click DFS Management.
In the console tree, under the Replication node, right-click the replication group that you want to create a diagnostic report for, and then click Create Diagnostic Report.
Follow the instructions in the Diagnostic Report Wizard.
Additional considerations
-
To create a diagnostic report, you must be a member of the local Administrators group on each server that you prepare a report for.
-
The amount of time necessary to generate a diagnostic report will vary based on a number of factors, including: DFS Replication health; the number of replicated folders; available server resources (for example, CPU and memory); WAN availability (connectivity, bandwidth, and latency); and the chosen reporting options. Because of the potential delay in creating diagnostic reports, we recommend creating diagnostic reports for no more than 50 servers at a time.
