Enabling Single Instance 
Storage (SIS) on the first 
volume disables SIS on 
the subsequent volumes 
When you enable SIS on the first volume using the 
Advanced tab of the Volume Properties window, SIS 
is disabled on subsequent volumes and no error 
message is displayed. 
To work around this issue, run the following command from the 
command prompt to fully enable the SIS features: sisadmin /i 
<volume>
When you enable SIS on subsequent volumes through the Graphical 
User Interface (GUI), the SIS service is stopped. You must restart the 
SIS service manually through the services.msc application for each 
volume.
