Here's the deal...I get error 801811A3. I do what the Microsoft site says to do...download FixIt. Well, great! Our virus software sees that as a threat. I then have to reboot everything to even get MS's other stellar piece of software (Zune) to find the update. Does it work? Of course not. I try this twice. What next? I use the MS phone support tool. It downloads software, says connect to Zune and update the phone. Surprise, surprise! I get error 801811A3 again. Guess who's going to give me new phones with the NoCanDo and updates preinstalled? Microsoft's software acumen does me proud.
