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.
