Event log píše toto:
"Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address ........ The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server."

"There was an error while attempting to read the local hosts file."

"The IP address lease for ..... the Network Card with network address ....... has been denied by the DHCP server ..... (The DHCP Server sent a DHCPNACK message)."

"There was an error with the Windows Location Provider database"
