Is there any reason you can't check just for a server OS? Something like

Code:

if instr(@ProductType,'Server') or instr(@ProductType,'Domain')
  ? 'This is a server'
endif


Quote:


@ProductType OS type. Possible values:
"Windows 95"
"Windows 98"
"Windows Me"
"Windows NT Workstation"
"Windows NT Server"
"Windows NT Domain Controller"
"Windows 2000 Professional"
"Windows 2000 Server"
"Windows 2000 Domain Controller"
"Windows XP Home Edition"
"Windows XP Home Edition Tablet PC"
"Windows XP Professional"
"Windows XP Professional Tablet PC"
"Windows Server 2003"
"Windows Server 2003 Domain Controller"
