I'm getting an interesting error after leaving an XP PC attached to the network unattended for an extended time. When coming back and trying to access a network drive, I get: "The system detected a possible attempt to compromise security."
Logging off and logging back on cures this but I don't know how to make it not happen.
If this is a school domain they may have a policy enforced where if a pc is inactive for a predetermined amount of time, you get dropped. So when you try to use your pc again, it doesn't see you as being logged on anymore. Does this happen to anyone else?
This is in my own home. I have Windows 2003 Server as the server and a few PCs and a Mac on the network. I have administrative rights.
The PC is left on. It was able to access network drives when initially logged on. After a number of hours one can't access the shared network drives and the above error is returned. Internet is uneffected.
The problem could be due to your network having a DHCP server configured to use DNS servers outside of your network. If you have a broadband router acting as the DHCP server then make sure the DNS server(s) in the DHCP scope only contain internal ip address of your router (assuming it has the DNS proxy facility).
If not just set up the server to do DNS and DHCP and that should fix it.
Good Luck
