Kenzo - your suspicions on this being a bad idea are correct. the reason why this is bad is for many reasons one the root of the system is on C the winnt dir may not be accessible via the guest account however with the plethora of exploits out there known and unknown it probably wouldn't take a whole lot to get by on the guest account. If the webmaster is testing a application for errors the better way to do this is not on a production box but in a mirrored environment in a safe area. as a rule of thumb default installs of anything are bad. another idea would be to create a specific user to do the error checking against with limited permissions to do the job. The other thing I noticed in your post is that it seems the webmaster techno talked you as you are new one of the things more experienced people will try to do is "get one by you" all you need to do is build the equation as follows define the business need define the impact and factor in the risk. if it looks like your going to get burned have his manager build a business case this allows you the time to research the idea as you are already doing by asking this forum... Best of luck to you...

Our webmaster seems to think that giving the guest internet user read access to the C drive is OK as long as you don't set IIS to list content and other stuff that I don't understand, since I don't know anything about running a website. I told him that by doing so, most subfolders will also take that permission, so if someone that knows what they're doing could compromise that account, they would have read access to almost the whole C drive. the box is a win2k server with IIS5. I believe he wants to do this for some error checking for a C or java program. The program suppose to check to make sure that the drive has enought space before it starts writing or copying things and for that it needs read access to the C drive. To me, even thought I don't know anything about programing and webhosting, it doesn't look right from the security point of view. Please give me some input on this if it's OK or not and why, so that I can tell him yes it's OK or NO it's not OK because of this and that. Thanks.
