I've been working with and setting up windows network's for several years and I just recently encountered a rather unusual problem.

A network which was working fine (seen with my own eyes) just yesterday is now causing many problems. The network just cannot see eaach other so here is the steps I went through:

- reset all network settings on each comp
- shutdown comps
- restarted router
- boot comps
- set up network again on each comp
- restart comps

Now the network worked, for about 2minutes... Then it bugged out again. So I repeated the above steps and again after about 2minutes the network bugs out...

Any advice?
