NetPoint is great! It's doing everything I want it do do so far :)
But there was one little trick that escaped me when it came to modifying the PollMe.vbs script. Took me ages to twig to it, so I'll record it here for any other dummies like me that may come wandering along :)
The documentation says "...set the strServerName variable to the name of the server hosting the NetPoint database."
The script says;
' Initialize the NetStudio database connection string.
strServerName = "<ServerName>"
What I didn't know was that I needed to include the name of the SQL Database server as well as the name of the server that it's running on!
So, not strServerName="MyServer", but (for example) strServerName="MyServer\SQLExpress"
Cheers!
