If you plan to use WAFS for Microsoft IIS content mirroring, do the following (for every version of IIS):
When setting up the software to do the mirror, shut off IIS for a few seconds when creating the new Job.
IIS must always be stopped before the Agent; IIS must always be started after the Agent is running.
On each computer on which an Agent is installed, enable Auto Explorer Refresh. (In the WAFS Agent Manager, click Tools > Options, then on the Setup and Preferences node, select the Auto Explorer refresh check box.)
Do not use the new drive letter.
