Sometimes you end up installing, uninstalling the Dynamic connector lots of times, especially in the bad old days where the connector would often forget your maps when you updated them.
Sometimes this can lead to the icon missing, I will also add they should create their own logo (BRAND IT)
I know it’s not a big deal and it’s really worthy of a blog post but it was really annoying me and it looked awful on a customer site.
if you click the change icon button it will pop up this path
to find the icon you need to replace %SystemRoot% which is refers to the directory where you installed Windows. Mine is C:\Windows but I guess you could be radical and named the drive something else (is that even possible!). You should end up with something like this
A word of warning you might not be able to just copy and paste the line above because your Dynamic Connector installation could have a different guid. Although oddly I have two installations with the same guid (but on different machines).
