I too now have issues with this new client 2 sp3. I had a client 2 sp2 ir5 and it worked flawlessly. I updated the win7 pc to client 2 sp3 and now it won't map the drives. Won't map my home folders or anything else. Yeah, it lets me get into the pc at least but you have to go to the BIG RED N and login that way to get your mapped drives.

I should NOT have to do anything special, no reg hacks, no searching for fixes or anything like that. The client version just before this new one worked great. Update and now it's broke.
