    server taking 2 IP's from router

    Hi All

    I ntoiced that our server it taking 2 IP's from the router. It never used to do this. The IP of our server is 192.168.1.200. Why has it now started using 192.168.1.220 as well?

    I know this is not the answer your looking for but shouldn't a server should really have a static ip set.

    Yh a server should only have one static IP address..

    Looks like you have another adapter been used bar the Network Interface card.. Do you have any more cards been used (network wise)

    Have been looking at this part, is this not some kind of VPN connection that is set up so cl.ients can connect to the server. I dont know much about VPN or how to set them up tho. I just googled "RAS Server (Dial In) Interface".

    That subnet mask is not a valid one are you sure you have copies all the details correctly?

    That appears to be a connection as a result of plugging into a modem.

    I copied & pasted from the ipconfig/all screen and that is what was displayed there

    No new modems have been plugged in but I know that a networkable external hard drive was plugged in sometime last week and the software for it was installed on the server. Could this have caused it as this taking 2 IPs thing only seems to have started since the hard drive was used?

    Thanks for all the replies

    Why?

    DNS and WINS servers must have fixed IPs but while it might be "tidier" to use fixed IPs on other servers I can't think of any reason why it should be so.

    Mystery solved. It looks like someone was attempting to setup a VPN connection.

    Sorry for wasting your time!

    I *so* want to say "told you so" .. but that would be childish and silly.

    Instead I will be childish and silly by going off to read some of Spike Milligan's poetry in peace and quiet now that *STAFF HAVE GONE HOME*!!!!!
