Server mysteriasly picks up a new IP

Posted on 2006-05-11

Our Server seems to have picked up a new IP Address on the 'PPP' adapter which wasnt there before. It is causing problems were some clients when you ping the host name 'server1' you get a reply from the PPP adapaters IP, not the servers NIC. This in turn is causing problems for these users connecting to some shares, or applications using specific directorys on the server arent resolving to the correct place.

I have up'd an image to an ftp, appologies if im not supposed to link here.....

The adapter listed first was not there previously, it seems to have just appeared and with that caused no end of problems. The only reference to it I could find was in the DNS managements Forward Lookup Zones which had an A Record which I removed. I then stopped/started the DNS services but this made no difference.

I am under quite a bit of pressure to get an answer to this, any help would be very much appreciated.

    do you have VPN enabled for users on your SBS?  it's suppose to have a seperate IP.  It seems though that you have it incorrectly routed in your Forward Lookup Zones.  You want to create an A record in the forward zone area with server1 pointing to the correct IP address

    then on the computers that are having problems you'll need to have them flush the dns by going to the command prompt and typing:

    ipconfig /flushdns
    ipconfig /registerdns

    that should resolve the issue.

    let me know.

    oh you should also run an ipconfig /flushdns and ipconfig /registerdns on server1
