Question:

Can you help me with this piece of code? This was taken right out of the Help example. The only thing I changed was the "BinaryPathName", "ServiceStartName" and "Password" to an account that I know is on my local workstations User group. I keep getting an Error 531.

AddExtender("WWWNT34i.DLL")
ServiceName="Computer Browser"
DisplayName="Browser"
BinaryPathName="C:\svcs\Listener.exs"
LoadOrderGroup=""
ServiceStartName="newtest"
Password="hello" 
createstring=Strcat(ServiceName,"|",DisplayName,"|",BinaryPathName,"|",LoadOrderGroup,"|",ServiceStartName,"|",Password)
ServiceType=256|16
StartType=3
ErrorControl=0
createflags=strcat(ServiceType,"|",StartType,"|",ErrorControl)
wntSvcCreate("", createstring, createflags, "","")
Message("Done","Added a service to the service control manager
database.") exit

Answer:

First try closing, then re-opening the service manager. I have found if you have the service amanger open while running the script, the service doesn't show up until you close and re-open the service manager applet.

My guess is that the service has already been added. I like to add a check to the beginning of my script to delete the existing service before attempting to create it, to avoid this type of problem....

ret = wntSvcStatus("", ServiceName, 0, 0)  
if ret==@TRUE
	wntSvcDelete( "", ServiceName, 1000)
Endif
