Scripting - Psexec problem when execute .cmd in task scheduler

I faced following problem executing, in task scheduler, following psexec command (trying to automate some tasks)

I could view cmd and psexec processes idle (from command line script worked well) and task was running indefinitevely.

Solution that I found was:

1. Execute psexec with different user to override first psexec window popup

2. Adding these bold parameters:

 psexec \\%%a -e -u domain\userdomain -p usernamepassword -h cmd.exe /c "c:\windows\system32\scriptname.cmd"

Server - How to Pass proxy.pac script to client with DHCP

If your company has proxy to browse internally and externally thought internet your problem would be to publish automatically that to clients.

There are several ways to deploy proxy to client's browser like Wpad, GPO, login script...

One that I would like to focuse is DHCP with option 252 that will pass to clients a proxy.pac script that, depending on which subnet client is, will setting up a differently proxy to clients.

proxy.pac can be published in several ways:


  1. Distribute the tested proxy.pac file either by emailing it to your users or by posting it on an internal web server.
  2. Distribute the configuration as a wpad.dat file, which is documented in the Publishing Proxy Information as a wpad.datFile Knowledgebase article. 
  3. Enforce the proxy configuration by Creating a Group Policy Object (GPO) on your Active Directory server. 

Here they are some articles useful:
