 Script name    : Get Publishing Point Limits (getlimits)  
 Script version : 1.0 
 Description    : Displays the resource limits  
                1. Max connected players
                2. Max bandwidth per player
                3. Max aggregate bandwidth 
for a publishing point on a server. 
                
 Command line parameters : 
           [-s <Server1>] 
           -p [Pubname]
 -s represents target server, -p represents publishingpoint name
 Example : getlimits -s Server1 -p pub1  
 Returns  : 
 1. Usage: getlimits [-s <Server1>] -p [Pubname] 
 2. Server %server% is not a valid WMS Server
 3.  invalid value specified for %parameter% 
 OS Requirements       :  Windows Server 2003 (all versions)
 Software requirements :  WMS Server 
 Scripting Engine      : Jscript
