Top 50 PowerShell Blogs

I just received word from Feedspot that they chose to include WagtheReal in their Top 50 PowerShell Blogs on the web. I’m very humbled, and while PowerShell was not the main focus of my blog, I increasingly turn to it to manage Windows and Citrix environments. I think it’s one of the most important pieces of technology that a Windows and Citrix administrator should learn and I hope that my PowerShell focus posts will continue to be informative to my readers.

Thanks,
Alain

Application woes: Solarwinds Advanced Subnet Calculator

bg_adv_subnet_calc_top

Solarwinds Advanced Subnet Calculator (ASC) is a great, freely-available tool to generates lists of IP4 networks. I recently ran into an issue installing it in a Windows 7 virtual desktop. It would run fine for administrators, but regular users received errors like this and this.

I broke out Process Monitor and Regshot to investigate what was going on here. I found that regular users could not register the SWLogo.ocx file listed in the above link. This makes sense as I had applied reasonable security on non-admins.
I reinstalled the ASC as the local admin (i.e. non-domain administrator) and that fixed one error for users, but a new one popped up. Running Process Monitor again, I found that ASC was expecting read/write permissions on

c:\programdata\Solarwinds\VB\Banners.

This folder contains a series of bitmap banner ads for Solarwinds products. Not at all unreasonable for a free tool. Once I modified permissions in the disk image to allow users to modify (ha!) this folder I was back in business.

Thanks,
