Note, I'm only half done with my coffee so...you never know.
Update: I just came back to the site and launched the model seems like the link is now http://windows.graphdat.com/agent/GraphdatAgent.exe which works...
Over the past year I switched to using git to deploy almost all of my apps & services and it is just so much better than what I was doing before (various cobbled together crap).
I even have git repos for things like my servers' .bashrc file ... you'd be surprised how useful that is.
Yes there are tools like puppet & chef and whatnot, but I think of those as better suited to dependencies than your actual code with its higher push frequency.
[UPDATE] might as well talk about how we do this:
In order to use "git push" from a development box to push to remote servers (rather than having them pull from a repo, which requires keeping a git repo accessible from your production boxes, which might not be convenient), you need two things:
1. On the server, run this:
git config receive.denyCurrentBranch ignore
2. On the server, write a .git/hooks/post-receive and make it executable. Its contents should be:
#!/bin/sh
# NB: hooks execute in the .git dir (not the repo root)
# and GIT_DIR is set to '.'; either one prevents "git checkout" from working
unset GIT_DIR
cd ..
git checkout -f # force checkout the current branch
