I've been fiddling around with the permissions on the D:\Steam folder on the four windows machines, and I think I've found a configuration that stops it needing an admin password to login to Steam for the first time on a computer. It may have also fixed some other permission problems.<div>
<br></div><div>I've documented this configuration at <a href="http://wiki.ucc.asn.au/Steam">http://wiki.ucc.asn.au/Steam</a>.</div><div><br></div><div>The basic gist of it is you allow gumby and Everyone all rights except the ability to change ownership or change the permissions. Then you made everything in the directory inherit those permissions, ensuring that the owner is SYSTEM. The problem seemed to be that Steam choked when trying to create a player directory in D:\Steam\steamapps, which it only does if you haven't logged in before.</div>
<div><br></div><div>The configuration still allows wheel and winadmin members to change permissions, but I haven't fully tested their effects. Try not to run Steam.exe as Administrator if you don't have to; I'm not sure if Steam will revert the permissions.</div>
