Although I haven't posted in a while, it hasn't been due to this particular blog's subject. In fact, our first major corporate deployment over 10 computers is now officially a success.
The new Windows 7 client machines are running fine; with users only having a minimal 1/2 hour tutorial on the new features to get them going. We had an old printer that had to be retired, but other than that - everything that was originally running in XP without rubber bands and twist ties is 100% functional, and dare I say 10% more functional than it was before we wiped and upgraded to Windows 7.
Some frustrations we have are with the Client side extensions. First, if you plan to push out printers - be aware that if you choose to reapply the map instead of "apply only once", every background refresh will un-map and re-map your printers. Some applications that cache the printer list fail miserably when this happens. Drive mappings are the same. The drives are less of a concern, unless you use databases like Access over the network. (These database applications report that the data connection has been lost as group policy processing occurs) We wish Microsoft would have checked the mapping and skipped it if it was as the settings in Group Policy indicated.
What are we missing? We sure wish other applications like AutoDesk's AutoCAD supported jump lists. We wish our PDF viewer (we don't use acrobat) integrated into the shell and allowed us to preview PDFs instead of having to open them. We also wish all our printer manufacturers had updated drivers. The staff wonder why the large format HP plotter appears like a multi-function fax machine. I wish we could group the printers by location.
