Can someone PLEASE help me? I am desperate... Be gentle I am new to using a MAC

Ok I am running 3 computers on my newtork

1. Desktop running windows vista which has the linksys router and comcast cable modem hard wired to it... this computer is mainly for printer sharing as I do not have a wireless printer at this time

2. IMac running Lion OSX 10

3. Dell Vostro 1510 laptop running windows 7 home premium

My issue is this. Up until last week I was not having any issues, this is important! I have always been able to access my mac via the network under windows explorer to watch moveis, transfer files etc. Last Thursday I installed Lion on the Mac and everything was working fine. On Sunday I turned off the Mac to move it to a different room and when I turned it back on I was not able to see it from any of the other computers on the network... I can see both of the PC's under finder on the mac but I cannot see the mac from the PC's... I did not change any settings on any of the computers it just decided to stop working. I called apple support about this thinking it must be a Lion issue but they went through every setting with me and found that it was set up correctly. I then called Microsoft and they did the same thing although I will admit that they were pretty clueless compared to the people at Apple. I am at my wits end here can anyone help me?
