I have 3 computers in my home environment, 2 laptops and 1 desktop. The 2 laptops are running Windows 7 and the desktop is running Windows Vista Home Premium. On my Vista PC, the NIS anti-spam function was not working in Outlook 2010. The fix for that was upgrading to NIS 2011. I upgraded from NIS 2009 to 2011 and it fixed the problem with NIS anti-spam not working in Outlook 2010, but I can no longer map network drives from my Windows 7 laptops to the Windows Vista PC (just upgraded to NIS 2010). After researching on the forums, there is a clear indication of a problem with NIS 2011 on Vista machines, but the only fix that I've seen indicated was to remove NIS and reinstall. The people that have done that have indicated that it did not fix the problem.
This is a big problem because I can't connect to this PC after upgrading to NIS 2011. It worked fine before the upgrade and I'm stuck now. Any help resolving this would be greatly appreciated.
