First time posting here. Heard good things about Geeks To Go so I thought I'd give it a shot since I'm stumped.

I have a machine that is unaccessible from any other machine on the same internal network where this machine resides. Just last week I was able to remotely access it using Remote Administrator, but come Monday morning I've been unable to access this machine using Remote Administrator or simply going through My Network Places. I am able to remotely connect to any machine on the network FROM this troublesome machine, but it will not allow any incoming traffic it seems. This machine can access the internet without problem. I thought maybe something was being blocked to the specific IP Address this machine was using, so I gave this machine the IP Address from another "working" machine on the network, but it still has the same issue, which tells me it's something on the machine itself blocking incoming connections? Just not sure anymore.

If anyone could shed some light, or point me in the right direction, that would be helpful. If you need any other information regarding this issue, please let me know.

Note: I'm no network administrator. I have limited networking knowledge, but am able to find my way around.

have you checked any firewalls on the computer that can't connect?

Our gateway is firewalled, but each machine internally does not have a firewall on it specifically. Machines run XP SP2, but I've turned off windows firewall upon installing. I was thinking it wasnt the firewall because connecting to the machines internally, there is no need to leave the network, but like i said before, I'm no network administrator so I'm not sure exactly how it all runs together (failed cisco networking).

Thanks for the response.

aww...cisco is easy hehe...if you had firewalls internally (I.E. the windows firewall) they could be blocking this kind of thing....what AV software are you running? is this a domain or workgroup setup?

lol... not even our instructor who was cisco certified could pass the new tests they came out with. But onward...

We run Norton Corporate Edition and all internal machines are part of a domain. We also run Active Directory. Thinking that could have been the problem, I had uninstalled Norton before, but still no luck. Other than windows firewall and Norton, there isn't anything else on each individual machine (program wise) that would block this. What is just so weird is that it worked last week.

We have a server that is responsible for doing LiveUpdates and scanning individual machines. After uninstalling and reinstalling Norton, the server picks up her machine name and IP Address, but when it trys to schedule a scan or scan at all? It says the machine is inaccessible. I'm guessing her machine sent this information to the Norton host machine, but is just not allowing any incoming traffic what so ever.

I've also used Radmin's Advanced IP Scanner to scan our IP range. It says her IP Address is "dead". Not sure if that program just uses a simple ping to indentify each IP Address? Unsure.

it probably uses PING ..most ip scanners do...this sounds like a firewall issue...norton doesn't install or disable the firewall very well...there's a chance that the windows firwall is in fact still on as well....sometimes when you uninstall something like norton...it will turn the windows firwall back on

Alright, I'll look into it a little further. Thanks for your help.
