RE: Server 2003 Network problems since IP address change

Tech-Archive recommends: Speed Up your PC by fixing your registry

Hi,

it is a AD run domain with a single DC. Previousley the old router provided
the DHCP addressing. When we moved offices we had BT come and install our
phone systems with a new router and hence the new addresses. This router has
proved very troublesome so I have disabled the dhcp server on it and setup
the same scope it was using on the DC.

ipconfig results :

Connection-specific DNS Suffix . :

The DC = 192.168.1.2
The router = 192.168.1.1

As per Meinolf Weber [MVP-DS] suggestion, I have just looked on the DC
under DNS and under 'Reverse Lookup Zones' there is an entry for 192.168.0.x
Subnet' with a list of pointers to computers and the old addresses they used
to hold. Could this be something to do with it?

Thanks for your help guys.

Hi, hopefully someone will be able to shed some light on this problem.

We have just moved offices and broadband providers. With the move came a
change of Ip addresses. we used to run on 192.168.0.1/254 and now we use
192.168.1.1/254.

Since the move I am getting loads of problems with GPO's not applying to
clients anymore and the biggest problem which is the server refusing access
to network drives. I have to manually un-map the drives and add them
again...most the times using a different username and password as I get the
error 'Multiple connections to a server or shared resource by the same user,
using more than one username, are not allowed' or a similar one which I
cannot now replicate.

Is this related to the IP address change? if so I musy have missed something
somewhere when I was updating the server.

Thanks for you help.

More information is needed before anyone can help you.

Is your network a domain or a workgroup?
If a domain, is it AD-integrated zone? More than one DC?

Does 2003 server provide DHCP for your network? Did you destroy old scope
and create a new one?

Please post ipconfig/all result for server and typical workstation.
