workstations not connecting to server2003smb after router install

By crwjoe ·
Help! I have recently installed a 3com dsl secure gateway router in an office. There os is Win2k3SMB server and it is the domain controller.

The ip address are manually set.
The server ip is
and primary dns is

The rest of the workstations had the same subnet, gateway, and dns. After I installed the router I turned the routers dhcp on and change the workstations gateway to
and set primary dns to
and secondary dns to

Every thing seems to be ok, but know the office manager says that they have to reboot the workstations a couple of times a day to get them to connect and be able to to use there software. They have trouble in accessing the shares on the server. I did not change anything on the server. If set every thing back to normal on the workstations no issue. I don't have much experience with DC's. Please help!

The problem is that you have 2 DHCP servers (router and server), which is not allowed. Run "Configure E-mail and Internet Connection Wizard". Click start>server managment>internet and email>connect to internet. It should find the router and ask to configure it. let it. Check out these 2 links:

Buy this book it got me into SBS Servers. You won't regret it:

here's a thought

you really want to create the computer and user accounts FIRST before joining computer to the domain. also you really want to use the System Management Console to create the computer and user accounts. If you don't, you won't put the computer and user accounts in the right OU.

in addition to Ken's book suggestion, get the Microsoft Press Small Business Server Administrators Companion. Has everything you need for installing and maintaining a SBS server and network. you can find it also at
