Totally forgot about this, sorry
Well, as I'm stuck in work and have nothing better to do I have done a quick test
For some reason my server denies me to connect remotely today so I tested it on standard win2000 workstation, I'll try it tomorow on win2003 server
Basically you need instsrv.exe and srvany.exe, they are part of the win2000 resource kit, but can be downloaded on the net - google is your friend
you put both files in a folder (I preffer c:\winnt)
the open up a command prompt, go to winnt, enter "instsrv HFS c:\winnt\srvany.exe" where HFS is your desired service name and is followed by the absolute path to srvany.exe
Good, service is now added
Second step is to go to the registry, go to HKLM/System/CurrentControlSet/Services/<name of your service>
Here you have to add a new key (folder), name it Parameters. In this parameters key you create a new string (right click > new > string, in right window), name is Application, and the value of the string is the absolute path to hfs.exe
That's it.
However you need to make hfs load the vfs definition file, are there any command line switches for this?
But the test works this way too - of course no folders are loaded because none are setup but you can test it and see that the page loads etc. Of course you can't change any setting nor view the log, to do that simply stop the service and start the exe manually
instsrv/srvany are good tools, I use them to install UD as a service on some systems where I want them run 7x24
