I tried the utility from OldNESJunkie. I liked the interface, but the TightVNC viewer failed to load properly. But the search and sorting features are good additions to Muad'Dib's creation.
Muad'Dib has created a solid utility. The only complaint we have is nit-picky about searching.
We are mostly using the description we have on each entry for identification, but if an auto-complete feature were to work on either field, then it would probably make a world of difference.
My contractor and I use this over in favor of the Microsoft SCCM remote assistant client. The only feature we have missed is the ability to search through the client list. We support around 300 PCs with this.
