IP address keeps bouncing
Posted on 2006-06-02
I’m hoping someone can point me in the right direction. The problem we are having is for some reason, the company’s IP is bouncing between out internal and external web addresses, and when that happens, the user at the workstation has to perform repair on the network connection to re-establish connectivity on the network.
For example, the internal address 10.6.2.9 to the webserver will shift to 67.X.X.X (which grants access into the company) at the workstation. After repair, it goes back to normal. This doesn’t happen to everyone at the same time, but will happen 5 or 6 times a day. On our internal network, you can’t come in from an external address, so the shift to 67 networks will stop Internet access.
A little background info: Outside world comes in via Cisco 3600 to PIX firewall; Windows 2003 server environment; three DNS servers; two WINS; seven sub-nets.
Extra info: recently moved FSMO roles Schema, Domain naming, PDC Emulator from one domain controller to another and ran DCPROMO to downgrade former boss server.
