exec() with a network path?

swjones

I'm running PHP 5 and IIS 5. When I run an exec() command to a network path, it doesn't work (even the IP address, so I know it isn't a resolve issue).

Specifically, I believe that the reason it isn't working is because the account that is running the program is IWAM_<machine>, a local account on <machine> that isn't authenticated on my network. The same commands work on the command line, but that's because I (an authenticated user on the domain) am running them, rather than the internet user account.

Anyone run into this before? Know how to change the internet user account, or set it to the logged in user?

You mean with a UNC address? Don't think so -- if you want to test it, open up a command window (or shell window) and try typing the command at the command prompt. It's basically doing the same thing, but it could also be a user auth thing as well.

I'd try it in the command window first.

Yes, I'm using a UNC address. I've tried doing a 'net use' first, but still no dice.

All of the UNC commands work fine at the command prompt, but not through the website -- I believe they're working at the command prompt because I'm authenticated on the domain, where the IWAM_ account is a local account, not on the the domain at all.

I'm not a Windows user, so I can't offer a lot of insight there... though I'm wondering if the backslashes might also need to be escaped. What does it return when you run the exec()?

swjones

I've escaped the backslashes. In the process window, the user IWAM_<machine> looks like it's running the program specified, but has consumed all my system resources and produces no output. When running from the command line, the output takes less than a second.

I believe there's a 'runas' command that you can use at the command prompt -- perhaps you can try to run that command as IWAM_<machine> to see what happens there.
