Error 1718. File FileName was rejected by digital signature policy

Earlier this week I had to setup a couple of new servers for our Mitel system, the process went simply enough, the brief was minimum Server 2003 SP2, so if you ignore the whole process of getting to grips with the installation of Server 2003 as a Virtual Machine (which went off without a hitch once I’d understood the concept of virtual drives!) I ran through the normal install, an install I’ve probably completed a hundred times or more by now. Feeling quite proud of myself for getting them setup so quickly I gave the details to the Engineers and went about my business. Only an hour later on to be told they can’t install one of the software packages, the error popped up was the same as the post title, anyway, here is the fix that I was able to use;

01. Start / Run / control admintools / OK.

02. Double-click Local Security Policy.

03. Expand Software Restriction Policies. If no software restrictions are displayed, right-click Software Restriction Policies and press Create New Policy.

04. Double-click the Enforcement Object Type in the right hand pane.

05. Check the All users except local administrators radial button and press OK.

06. Shutdown and restart your server.

07. Install the package while logged on as a user who is a member of the local Administrators group.

08. Repeat steps 1 – 4.

09. Check the All users radial button and press OK.

10. Shutdown and restart your server.

Evidentially this is as a result of the server having insufficient contiguous memory to verify that the package is correctly signed.
