Vista - a fix to connected with limited access

If any one is interessted if have fixed my network problem "connected with
limited access". I took the quick fix and decided that i would back up my
personal data and set windows to it factory settings. however if this isnt a
option for some of you i found that there was a diffrence in the networking
section of my device manager (control panel, device manager) previously there
were to item called isatap (with some numbers after that) they both had
yellow warning signs next to them and on there propeties they both sed not
working code 10. On the new version these to item were not there even after i
had got all windows updates. i beleive that windows had put out some bad
updates however becuase it was not possible to connect to the internet to
download any new ones you couldnt fix this problem and get out of the cicrle.
So to conclude I would suggest uninstalling these to items or doing a system
restore to factory settings
