The problem is I have no clue what computer it is. When I put the IP address in a browser I am required to log in to a Linksys BEFSX41, and I do not own any Linksys equipment.
Main Topics
Browse All TopicsMy domain controller seems to have failed or something. It is a w2k3 server and it just won't browse anymore. It was my dhcp server, but it is not giving out IP addresses and when I take off the hard coded address it gets a completely different number (I have a 192.168.100 network but it is giving itself an IP address from a 192.168.1 network). In addition to this all computers are getting this same IP range (.1 instead of .100). Does anyone have any suggestions?

Linksys BEFSX41 is Etherfast Cable / DSL Firewall Router with 4-Port Switch which I presume is acting as a DHCP server. Enter 'admin' into the password field, leave username blank, this is default password and try to disable DHCP server or try to locate this device and remove it from network. Somebody has connected this device to your network, if you didn't try asking co-workers.

Hi!
I'm not sure I understand you completeley but when you mention, that client computers are getting addresses even when your DHCP is not workingyou should look for rouge DHCP server on your network. Go to command prompt on one of the clients with IP from 192.168.1.0/24 range and run the following command: "ipconfig /all". Examine the output, look for IP address next to DHCP Server. This is the IP number of your rouge DHCP server. Locate this computer on your network, and shut down DHCP service.
