Thanks again.
I hadn't heard of the windows service control manager! I have now downloaded such a thing from http://www.nttools-online.de/english/srvmgr.htm, and sure enough the service was listed, but not started.
I have now started it, and it does seem to be working! Hoorah! Thanks.
Any chance you could update the sticky on this subject to include starting the service - what is the best way to access the service control manager?
