IIS访问同一域中的远程服务器

I have a server A where some logs are saved, and another server B with a web server (IIS) on it.

I can access serverA from Windows Explorer with zero problems, but when I want to access it from serverB with some PHP code, it doesn't work.

I made a python script that accesses the file from serverA on serverB. It works if I run that script from CMD, but when I run that script from PHP code it doesn't work anymore.

I run IIS server as a domain account that has access on serverA

I try to run that as LocalService, NetworkService, System, LocalUser but no success.

That script is a simple open command, so problem it's not from python.

Resolved. Uninstall IIS and use XAMPP. No problem found till now, everything works okay. So use XAMPP/WAMP!

Since you provide no example code or describe what you are doing... There are a few things to consider.

1. Anything running in the context of a webpage in IIS is running in a different context than a logged in user.
2. The first part of that is simply what file system level permissions might be different for the IIS user account. The proper way you want to handle that is by assigning the necessary changes at the filesystem level for the IIS user. Do not change the IIS user if you do not understand the ramifications of doing that.
3. The next part is that certain operations cannot be done in the context of the IIS user account (regardless of account permissions), because there are certain things that only a logged in user with access to the console/desktop can do.
4. Certain operations called from IIS are purposely blocked (shell.execute) regardless of permissions, account used, etc. This occurs in versions of IIS in Windows Server 2008 and later and is done for security.
