1 commercial rr connection on a home network - I'm experimenting.
This network was up and running for over 1 year - all computers had full communication with each other.
I changed out two computers for new dual core Intel machines with HPs XP media center edition, which my research indicates is XP Pro.
That's when computers started to be not available. I've seen others with this same complaint, so I want to start a thread which can explore why this is happening and how we can fix the issue - the whole permissions topic is very difficult to track down.
I've got a BEFSR81 Linksys router connected to the cable router (not a cable modem - static IP) and 7 computers and 6 cameras connected to a Linksys WRT54G with a workgroup switch hanging off it. The wireless router is connected to the wired router and I have only my work computer (which runs a VPN) hooked to that. All wired and wireless computers and cameras are connected to the 54G or the workgroup switch.
It WAS working very well. All equipment can still access the internet. The main issue is the shared printer which nobody can use but the computer it's directly connected to. I've gotten over the shared files thing by just using email to send files machine to machine - stupid but effective. @#$%^&
I've gone through everything many times - my opinion is that a security program changed something but I can't fathom why it would do it to every machine on the net - the cameras were not affected but they aren't on the dhcp server. But I cannot find what has changed - everything appears correct.
I started taking the net apart but haven't had a lot of time to work with it since there are so many components to check out. The one thing that worked was when I took sharing, etc. off of every computer and then started it up again.
Now, I can actually print from ONE of the machines to the printer on the printer computer. But still, no other computer can do this. There's some strange stuff going on. Why this one machine can connect is a mystery - all I did was turn sharing off and then on. btw, the computer I'm on is one of the new HPs and the one with the printer is a 2Kpro job.
For example, I just pinged these two machines from the other one and both are conversant. The printer machine is 192.168.1.100. It can ping 192.168.1.101 not a problem and can see it's files. 101 can ping 100 with no problem but when I try to run 192.168.1.100 I get that nasty message:
\\192.168.1.100 is not accessible. You might not have permission to use this network resource. Contact the administrator of this server to find out if you have access. Access is denied.
Unfortunately, I'm the administrator. Why it runs one way and not the other has to be part of the mystery.
As I said, a lot of people are having this problem and I agree it's probably a security issue - but I've tried to turn any firewalls off. There might be some residual software still running but I've turned it off.
I'll take any and all suggestions, guys!!
And I believe it's something very simple. But I cannot find it.
Thanks to all,
