Well, I should have followed up before now. We got it working. As far as the VMs, they are nothing special at all. Very generic virtual hardware config (vmware esxi template defaults for 32-bit Windows XP). But where the problem seems to be is that the .zip download that has server and viewer combined, the server installable hangs (either when run from within the .zip or with the .zip extracted). But, just for grins, I downloaded the standalone server installable .msi, and it installed and ran without a hitch! We tried this same scenario on two other guest VMs and the same result. For some reason, the server installable that is packaged with the .zip would not fly for us. So, our problem is solved, but the .zip is still a mystery as surely if the server installable in the .zip were corrupted, you would have had people screaming about it long before now. We even re-downloaded the .zip. Not saying it might not still be something on our end, but whatever, an FYI for you. Thanks.
