Hi Monks,

I am replying to this message months later just so somebody can find it with SuperSearch (or Google) and not waste the time I did this week.

Problem: I built a tool to allow users to selectively synchronize files on two servers, but was unable to access the files. The idea was to just mount one server on the other as a mapped drive, but for some reason it didn't work.

The solution: (it is so simple it is sick..)

• Create the same name account on both computers with the same password.
• In the Computer Management console (right click on My Computer) find the web server settings and click on your perl program.
• Open its properties and in Anonymous Access and Authentication Control, Click Edit, leave Anonymous Access checked, and click Edit next to it.
• Here it says something like IUSR_YOURCOMPUTER which is the user IIS runs as, and a mysterious password you don't know.
• Change this to your newly create account (like COMPUTERNAME\loginname) and password.
• Note: You cannot change it back because somewhere it is cached and even if you delete it or try copying something over it, the new login is remembered for that file's name.
• Then set permissions of various folders as necessary so you can read/write as needed.
• Make sure you have got some good security on that program (I used SSL and a good login/password, plus encryption of a block of data which persists through forms) since that is a powerful user now.
• This could also be done if you have a single user belonging to a domain which includes both computers.

There is some information about setuid in unix and windows here.

Hope this helps you.
