Printer install script hangs when being ran as part of imaging with MDT RRS feed

  • Question

  • I have created the following script (and many others like it for different printers) that works perfectly when ran on it's own. However, when it is ran as part of the imaging process using MDT, the printer gets installed, but the command line never exits allowing the script to move on to set the printer as the default printer. The reason I am doing this is to make the printer a local printer so that no matter who logs into a particular computer, will get the printer. Group Policy really isn't an option for scripting printers because of the large number of students and our Active Directory is no long broken down by Room numbers in each school. All student computers are put in one OU and all staff computers are put into another OU under each school OU.

    There is probably a better way of doing this, but I know enough VBScript coding to get by and zero PowerShell coding. I've been meaning to learn, just haven't had the time.

    So, ultimately, my question is, does anyone know what might be the issue that when the script is ran by double-clicking on it, it works perfectly, no matter if logged in as a domain user of the local Administrator account, but when ran through MDT, it hangs up? The network share the scripts are running from have permissions set up correctly. The user account that is used when the script is launched through MDT is the local Administrator account. There are no error messages on the screen, but while the script is hung up and I try to run another script, I do get an "Operation could not be performed. error 0x000006be." That's the entire error message. Nothing in Event Viewer about this error. I've read this could be anywhere from a driver issue to a Print Spooler issue. I know it's neither of these, because when the port is created, I am stopping/restarting the Print Spooler service and the driver is the correct driver. I do know it is getting hung up on the rundll32 command, because if I put a wscript.echo after calling the command line, the echo never comes up.

    I've been up all night working on this issue and I'm probably not explaining it correctly and leaving some things out, so please ask questions and I'll try to answer. I'm using a similar script (similar in the way this script is written) to update the BIOS on HP computers and it works perfectly every time.

    Thanks for your help,

  • I think I found the issue, which isn't with the script or MDT. THe issue is because the computer is not joined to the domain when the printer is getting installed. Because I'm using the HP Universal Print Driver and trying to connect to the Print Server share, there is no authentication to get to the Print Server Share in place. I tested this by removing a computer from the domain, mapping a drive to the location of the printer script and when ran, I get a popup from Windows stating a program running on this computer is trying to display a message. When I click on SHow Message, I get the following screen.


    So, now it looks like I need to move this to a different forum.
