Hey uli_glueck, you may need this file- vbrun60sp5.exe - it's a free download . I didn't do anything special to get the vbs mentioned by Sidewinder to work.
Bil, actually, there is code or something (there are programs that close the cd tray), to close the cd tray, I've tried various vbs's listed by different people, but haven't found one that works yet. Yes, I could use one of the programs, but I am interested in learning the code, vbs or whatever. BTW, I haven't seen anything to open all cd trays on a network.
