One computer on my network keeps falling off
There are usually 3 computers on my network at any given time with a 4th occasionally. My wife's computer seems to fall off somehow at irregular intervals. Actually it is still on the network as it can still see the shared drive where I keep a lot of files and she can still print over the network, she just cannot use explorer without a reboot. The only way to get back on is to reboot - closing and opening explorer will not work. I cannot predict frequency or timing of this behavior, but it is every time she used the computer.
I will detail the environment and then the steps I have taken (unsuccessfully). One important thing is that my computer NEVER has this problem and I have never seen it on my laptop although that one is for work and I don't surf the internet much on it. It is unaffected by whether other computers are on or not - it can happen on it's own or when I am online.
Cable Modem - Motorola Surfboarrd
Lynksys Router - BEFSR41 4 port wired
Windows XP OS
P4 2.53
640M RAM
Norton AntiVirus 2003 Updated regularly
Formatted Hard Drive / Reinstalled Windows
Ran all spyware checkers (Adaware, CS Shredder, Spybot Search and Destroy, Hijack this!) I doubt it is a virus or a spyware thing - it had the problem on a fresh install.
Changed out NIC
Changed to fixed IP
Added additional DNS Servers from different sources (shuffled order).
If you are going to tell me not to run IE or that I should be running LINIX or something, please use the back button. This is not realistic for my wife and her computing needs. This has been going on for quite some time and I cannot fix it. Please help any way you can. This problem has been very frustrating for at least a year and a half.
